CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. provisional patent application 62/693,545 filed Jul. 3, 2018, the disclosure of which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to a composition that can be used to relax facial muscles and/or reduce the appearance of fine lines or wrinkles. The composition can include a combination of plant-based extracts such as Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and Acmella oleracea extract.

B. Background

Certain types of wrinkles develop over time on facial skin due to repetitive muscle contraction. These types of wrinkles are typically referred to as rhytides, examples of which can include frown or glabellar lines, forehead lines, crow's feet, bunny or nasalis lines, dimpled chin, smile lift lines, lip lines, etc. Currently, a wide variety of commercially available treatment materials are available and are purportedly effective as facial muscle relaxants/muscle contraction suppressants. These materials are said to be capable of reducing the appearance of such wrinkles. Non-limiting examples of such treatment materials include injectable neuromodulators such as Botox (onabotulinumtoxinA), Dysport (abobotulinumtoxinA), or Xeomin (incobotulinumtoxinA). Other examples include topically administered treatment materials such as chemical compounds (e.g., gamma-aminobutyric-acid) and peptides (e.g., acetyl hexapeptide-3).

Various problems are associated with injectable neuromodulators, such as allergic reactions, rash, itching, injection site reactions (bruising, bleeding, pain, redness, swelling, or tenderness), muscle stiffness, fever, cough, sore throat, flu-like symptoms, neck or back pain, and the potential to spread from the injection site to other parts of the body, resulting in serious risks including difficulty talking, swallowing or breathing, muscle weakness, drooping eyelids, and blurred or double vision. Similarly, chemical compounds have their own drawbacks such as skin irritation and potential allergic reactions. Aside from the physiological problems associated with injectable neuromodulators and chemical compounds, these elective cosmetic procedures can be cost-prohibitive for a large segment of the population who may benefit.

There have been a few attempts to produce natural-based ingredients that have the ability to relax facial muscles. One such attempt is the development of Acmella oleracea extracts. While these extracts may offer some muscle relaxation effect, the effect may not be sufficient to effectively relax facial muscles and reduce the appearance of fine lines or wrinkles.

Thus, previous attempts to improve the visual appearance of skin have been shown to have various drawbacks such as high costs, medical risks, skin irritation, prolonged recovery periods, or inefficient delivery of the promised skin benefits.

SUMMARY OF THE INVENTION

The inventors have identified a solution to at least some of the problems associated with treating fine lines or wrinkles. The solution resides in a combination of plant-based ingredients that is effective at reducing muscle contraction of facial muscles. In one particular aspect, the facial muscle contraction can be reduced by reducing contraction of myotubes via reducing an influx of calcium levels in the myotubes. Reducing the influx of calcium levels in the myotubes can reduce or inhibit an action potential in the myotubes, thus reducing or preventing muscle contraction. This combination of ingredients also has the ability to modulate biochemical pathways that can further help reduce the appearance of fine lines or wrinkles such as by stimulating collagen production in skin (e.g., keratinocytes or human dermal fibroblasts) and/or reducing enzymatic activity or production of enzymes associated with the degradation of extracellular matrix proteins (e.g., matrix metalloproteinase (MMP) enzymes such as MMP-1, MMP3, and/or MMP-9). Still further, the combination of ingredients also has the ability to increase collagen expression and laminin production in skin cells (e.g., keratinocytes or human dermal fibroblasts). The combination of the plant-based ingredients include at least two of or all three of Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and/or Acmella oleracea extract. This combination of plant-based ingredients can be used to create topical skin compositions that reduce the appearance of and/or prevent the formation of fine lines or wrinkles, including deep facial line wrinkles or rhytides that can be linked to repetitive facial muscle contraction over prolonged periods of time (e.g., 1, 2, 4, 6, 8, 12, or more months or several years). Notably, the combination of ingredients can be used to reduce the appearance of and/or prevent the formation of both static and dynamic fine lines or wrinkles.

In one aspect of the present invention, there is disclosed a method for reducing muscle contraction of a facial muscle in a person. In another aspect, there is disclosed a method for reducing the appearance of a fine line or wrinkle on a person's skin. The method can include topically applying to skin a composition comprising: (a) an effective amount of Rosmarinus officinalis leaf extract; (b)an effective amount of Lavendula stoechas extract; and/or (c) an effective amount of Acmella oleracea extract, wherein topical application of the composition to facial skin reduces muscle contraction of the facial muscle or wherein topical application of the composition to skin reduces the appearance of fine lines or wrinkles on a person's skin. Additionally, or alternatively, topical application can include rolling a micro-roller across the person's skin to increase penetration of the composition into the skin. In certain aspects, the composition includes Rosmarinus officinalis leaf extract and Lavendula stoechas extract, Rosmarinus officinalis leaf extract and Acmella oleracea extract, Lavendula stoechas extract and Acmella oleracea extract, or all of Rosmarinus officinalis leaf extract, Lavendula stoechas extract and Acmella oleracea extract. In certain aspects, facial muscle(s) that is/are contracted can be positioned directly under the skin where the composition is applied. In other aspects, facial muscle(s) that is/are contracted can be in close proximity to the skin but not directly underneath the skin where the composition is applied (e.g., within 3 centimeters, preferably with 2.5 cm, or more preferably within 2 cm, or even more preferably within 1.5 or 1 cm of the area of the skin that the composition has been applied to). The facial muscle can be a glabellar complex muscle, an orbicularis oculi muscle, a depressor muscle, or a frontalis muscle, or any combination thereof. Alternatively, the composition can be applied to non-facial skin (e.g., hands, thighs, neck, buttocks, dcollet region, feet, etc.) and can lead to reduced muscle contraction of muscles directly under the skin where the composition has been applied or in close proximity to the skin but not directly underneath the skin. In instances where the composition is applied to a fine line or wrinkle, the fine line or wrinkle can be a rhytide, and reduction in muscle contraction of the facial muscle reduces the appearance of the rhytide. In other instances, the fine line or wrinkle is not a rhytide.

The extracts used in the compositions of the present invention can each individually be obtained from water as an extracting solvent (e.g., aqueous extract), alcohol as an extracting solvent (e.g., alcohol extract), or a polyol as the extracting solvent (e.g., polyol extract), or any combinations of such extracting solvents (e.g., aqueous-alcoholic extract, aqueous-polyol extract, alcohol-polyol extract or aqueous-alcoholic-polyol extract). Non-limiting examples of alcohols can be methanol, ethanol, propanol, butanol, petnanol, hexanol, heptanol, octanol, etc. Non-limiting examples of polyols can be ethylene glycol, propylene glycol, glycerol, erythritol, xylitol, mannitol, volemitol, etc. Additionally, other extracting solvents can be used such as additional hydrophilic solvents or lipophilic solvents (e.g., methane, ethane, butane, propane, hexane, heptane, octane, dimethyl sulfoxide (DMSO), N-methyl-2-pyrrolidone (NMP), carbon dioxide such as use of carbon dioxide (CO 2 ) in supercritical extraction techniques). CO 2 supercritical extraction can include filling a column with ground dried plant material and pumping supercritical liquid carbon dioxide though the column at very high pressure (200-400 Bar), and then collecting the resulting extract.

In a preferred instance, the Rosmarinus officinalis leaf extract can be obtained from the leaf of Rosmarinus officinalis . The leaf can be subjected to a eutectigenesis extraction process using a fluid extraction mixture comprising betaine or hydrated betaine, a hydrogen bond donor compound (e.g., polyols, organic acids, etc.), and water. The eutectic extract can then be used in the compositions of the present invention. In some preferred instances, the hydrogen bond donor is an organic acid, preferably lactic acid. Eutectigenesis utilizes eutectic solvents which are mixtures of compounds having melting points lower than those of their constituents taken in isolation. In another preferred instance, the Lavendula stoechas extract is from a combination of the flower, leaf, and stem portions of Lavendula stoechas , and the extract can be prepared by subjecting these portions to a supercritical extraction process using carbon dioxide (CO 2 ) as the solvent. The supercritical CO 2 extract of Lavendula stoechas flower, leaf, and stem (flower/leaf/stem) can then be used in the compositions of the present invention. The CO 2 supercritical extract of the Lavendula stoechas flower/leaf/stem can also be mixed with caprylic/capric triglycerides and then used in the compositions of the present invention. In still another preferred instance, the Acmella oleracea extract is from the combination of the flower, leaf, and stem portions of Acmella oleracea , and the extract can be prepared by subjecting these portions (flower/leaf/stem) to a hydro-alcoholic (preferably hydro-ethanolic) extraction process or a hydro-alcoholic-polyol extraction process. The polyol in preferred instances can be 1,3-propanediol. The alcohol can be removed from the resulting extract. The Acmella oleracea extract can be then be used in the compositions of the present invention. Thus, in a preferred instance, the Rosmarinus officinalis leaf eutectic extract, the Lavendula stoechas flower/leaf/stem supercritical CO 2 extract, and the Acmella oleracea flower/leaf/stem hydro-alcohol-polyol extract can be used in the compositions and methods of the present invention.

An effective amount of Rosmarinus officinalis leaf extract in the composition can be 0.00001 to 25% w/w or any range therein (e.g., 0.00001 to 10% w/w, 0.00001 to 5% w/w, 0.00001 to 2% w/w, 0.00001 to 1% w/w, 0.00001 to 0.5% w/w, or 0.001 to 1% w/w, 0.01 to 1% w/w, 0.1 to 1% w/w. or 0.001 to 2% w/w, 0.01 to 2% w/w, or 0.1 to 2% w/w). An effective amount of Lavendula stoechas extract in the composition can be 0.00001 to 25% w/w or any range therein (e.g., 0.00001 to 10% w/w, 0.00001 to 5% w/w, 0.00001 to 2% w/w, 0.00001 to 1% w/w, 0.00001 to 0.5% w/w, or 0.001 to 1% w/w, 0.01 to 1% w/w, 0.1 to 1% w/w. or 0.001 to 2% w/w, 0.01 to 2% w/w, or 0.1 to 2% w/w). An effective amount of Acmella oleracea extract in the composition can be 0.00001 to 25% w/w or any range therein (e.g., 0.00001 to 10% w/w, 0.00001 to 5% w/w, 0.00001 to 2% w/w, 0.00001 to 1% w/w, 0.00001 to 0.5% w/w, or 0.001 tot % w/w, 0.01 to 1% w/w, 0.1 to 1% w/w. or 0.001 to 2% w/w, 0.01 to 2% w/w, or 0.1 to 2% w/w).

The compositions of the present invention can reduce contraction of myotubes. This can be done by reducing the influx of calcium into the myotubes, which can reduce or prevent an action potential from occurring in the myotubes. By reducing or preventing action potential development, contraction of the myotubes can be reduced or prevented. Notably, each of Rosmarinus officinalis leaf or an extract thereof, Lavendula stoechas or an extract thereof, and/or Acmella oleracea or an extract thereof has been shown by the inventors to reduce or prevent an influx of calcium into myotubes and to reduce or prevent muscle contraction. The compositions of the present invention can also stimulate collagen production in skin cells (e.g., keratinocytes and/or human dermal fibroblasts). In particular, it was discovered in the context of the present invention that Acmella oleracea or an extract thereof can increase collagen production in skin cells. The compositions of the present invention can also stimulate laminin production in skin cells (e.g., keratinocytes and/or human dermal fibroblasts). In particular, it was discovered in the context of the present invention that Acmella oleracea or an extract thereof can increase laminin production in skin cells. The compositions of the present invention can also reduce or inhibit matrix metalloproteinases (MMP) 1, 3, and 9 activity or production in skin cells (e.g., keratinocytes and/or human dermal fibroblasts). In particular, it was discovered in the context of the present invention that the Rosmarinus officinalis leaf or an extract thereof can reduce or inhibit each of MMP-1, MMP-3, and MMP-9 activity or production in skin cells. The skin can be facial skin such as skin located on a person's forehead, cheeks, chin, orbital area region (e.g., under the eyes, adjacent to the eyes such as where crow's feet form, eyelid, etc.). In certain preferred aspects, the facial skin is forehead skin or orbital area region skin, especially where crow's feet develop. Still further, the compositions of the present invention can be used to increase skin firmness, which can aid in reducing the appearance of loos, sagging, and/or flaccid skin.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

A discovery has been made that provides a solution to at least some of the problems associated with current methods that are used to treat fine lines or wrinkles in skin, including both static and dynamic fine lines or wrinkles. Fine lines are typically characterized as smaller and shallower (e.g., generally less than two millimeters in depth) when compared to wrinkles, which have deeper lines (e.g., generally two or more millimeters in depth). Static fine lines or wrinkles are typically associated with fine lines or wrinkles that are present on skin that is relaxed/not-moving. By comparison, dynamic fine lines or wrinkles appear on skin with skin movement associated with muscle contraction. The solution is premised on using a combination of at least two of, and preferably, all three of, Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and Acmella oleracea extract in topical skin compositions to reduce muscle contraction, preferably reduce muscle contraction in facial muscles. It is believed that the combination of these ingredients can help reduce the appearance of static and/or dynamic fine lines or wrinkles on at least three levels: (1) reducing muscle contraction in instances where muscle contraction can form the presence of fine lines or wrinkles (e.g., dynamic fine lines or wrinkles); (2) increasing collagen production in skin (e.g., in skin cells such as keratinocytes and/or fibroblasts), which can allow for more full and firm skin, which can lead to reduced appearance of static and/or dynamic fine lines or wrinkles; (3) decreasing matrix metalloproteinase (MMP) production or activity (the terms production and activity can be used interchangeably throughout this specification) in skin such as MMP-1, MMP-3, and/or MMP-9 production or activity to further help reduce the appearance of static and/or dynamic fine lines or wrinklesMMP enzymes can breakdown or degrade extracellular matrix components such as collagen, fibronectin, laminin; proteoglycans, and vitronectin, which can lead to the formation of fine lines or wrinkles; and (4) increase laminin production in skin (e.g., skin cells such as keratinocytes and/or fibroblasts)laminin is a structural glycoproteins located in the DEJ. Considered a glue that holds the cells together, laminin is secreted by dermal fibroblasts to help facilitate intra- and inter-cellular adhesion of the epidermal cells to the DEJ.

These and other non-limiting aspects of the present invention are described in the following sections.

A. Active Ingredients

The present invention is premised on a determination that a combination of active ingredients Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and/or Acmella oleracea extractcan be used to reduce muscle contraction of a facial muscle, reduce and/or prevent facial fine lines or wrinkles, reduce dynamic facial wrinkles and forehead wrinkles that are caused due to repetitive facial muscle contraction (e.g., rhytides), increase collagen production, reduce a matrix metalloproteinase, including one or more of matrix metalloproteinase 1, matrix metalloproteinase 3, and matrix metalloproteinase 9, firm skin, and/or reduce the appearance of loose, sagging, and flaccid skin.

Rosmarinus officinalis leaf extract is an extract from the leaf of Rosmarinus officinalis. Rosmarinus officinalis is native to the Mediterranean region, and is a woody, perennial herb with fragrant, evergreen, needle-like leaves and white, pink, purple, or blue flowers. It is a shrub that can reach up to 1.5 meters in height with leaves that are about 2 to 4 cm long with green (top surface) and white (bottom surface) coloring. In a preferred instance, the Rosmarinus officinalis leaf extract can be obtained from the leaf of Rosmarinus officinalis . The leaf can be subjected to a eutectigenesis extraction process using a fluid extraction mixture comprising betaine or hydrated betaine, a hydrogen bond donor compound (e.g., polyols, organic acids, etc.), and water. In particular, the leaf portion can be crushed or macerated and then subjected to the aforementioned eutectic fluid extraction mixture to obtain a eutectic extract. The eutectic extract can then be used in the compositions of the present invention. In some preferred instances, the hydrogen bond donor is an organic acid, preferably lactic acid. Eutectigenesis utilizes eutectic solvents which are mixtures of compounds having melting points lower than those of their constituents taken in isolation. In some instances, Rosmarinus officinalis is commercially available. In some instances, Rosmarinus officinalis can be supplied by Naturex (France) under the trade name ROSEMARY EUTECTYS BLA. It was discovered in the context of the present invention that Rosmarinus officinalis leaf extract can reduce or inhibit contraction of myotubes by reducing or inhibiting an influx of calcium in the myotubes and reducing or preventing the occurrence of an action potential. It was also discovered that Rosmarinus officinalis leaf extract can inhibit or reduce MMP-1, MMP-3, and MMP-3 production or activity in skin cells (e.g., keratinocytes or human dermal fibroblasts).

Lavendula stoechas extract is an extract from the plant Lavendula stoechas. Lavendula stoechas is native to the Mediterranean region, and is an evergreen shrub that is about 30 to 100 cm tall with greyish and tomentose leaves that are about 1 to 4 cm long. In a preferred instance, the Lavendula stoechas extract is from a combination of the flower, leaf, and stem portions of Lavendula stoechas . These portions can be combined and then crushed or macerated or crushed or macerated and then combined. The resulting crushed or macerated flower/leaf/stem material can then subjected to a supercritical extraction process using carbon dioxide (CO 2 ) as the solvent. The supercritical CO 2 extract of Lavendula stoechas flower/leaf/stem can then be used in the compositions of the present invention. The CO 2 supercritical extract of the Lavendula stoechas flower/leaf/stem can also be mixed with caprylic/capric triglycerides and then used in the compositions of the present invention. In some instances, Lavendula stoechas extract is commercially available. In some instances, Lavendula stoechas can be supplied by Barnet Products LLC (Englewood Cliffs, N.J. (USA)) under the trade name STOCHEY'S. It was discovered in the context of the present invention that Lavendula stoechas extract can reduce or inhibit contraction of myotubes by reducing or inhibiting an influx of calcium in the myotubes and reducing or preventing the occurrence of an action potential.

Acmella oleracea extract is an extract from the Acmella oleracea plant. Acmella oleracea can be found in South America, Madagascar, and the Mascarene Islands. In a preferred instance, the Acmella oleracea extract is from the combination of the flower, leaf, and stem portions of Acmella oleracea . These portions can be combined and then crushed or macerated or crushed or macerated and then combined. The resulting crushed or macerated flower/leaf/stem material can then be subjected to a hydro-alcoholic (preferably hydro-ethanolic) extraction process or a hydro-alcoholic-polyol extraction process. The polyol in preferred instances can be 1,3-propanediol. The alcohol can be removed from the resulting extract. The Acmella oleracea extract can be then be used in the compositions of the present invention. In a preferred instance, the Acmella oleracea flower/leaf/stem extract can be obtained from a hydro-ethanol-1,3-propanediol solvent mixture. The resulting extract can then be used in the compositions of the present invention or can be further processed to remove the ethanol and can then be used in the compositions of the present invention. Alternatively, the extracting solvent can be a combination of water and polyol, preferably 1,3-propanediol, without an alcohol. The amounts of water, alcohol, and/or polyol present in the reaction mixture can be modified as desired. In some instances, Acmella oleracea extract is commercially available. In some instances, Acmella oleracea extract can be supplied by Gattefoss (France) under the trade name GATULINE EXPRESSION AF. It was discovered in the context of the present invention that Acmella oleracea extract can reduce or inhibit contraction of myotubes by reducing or inhibiting an influx of calcium in the myotubes and reducing or preventing the occurrence of an action potential. It was also discovered that Acmella oleracea extract can increase both collagen production and laminin production in skin cells (e.g., keratinocytes or human dermal fibroblasts).

The extracts described herein can be extracts made through extraction methods known in the art and combinations thereof. Non-limiting examples of extraction methods include the use of liquid-liquid extraction, solid phase extraction, aqueous extraction, ethyl acetate, alcohol, acetone, oil, supercritical carbon dioxide, heat, pressure, pressure drop extraction, ultrasonic extraction, etc. Extracts can be a liquid, solid, dried liquid, re-suspended solid, etc. In certain instances, each of the extracts can be prepared by: (i) obtaining the desired plant part (e.g., leaf, stem, bark, flower, seed, etc.) or whole plant; (ii) crushing or macerating the plant part or whole plant; (iii) optionally drying the crushed or macerated plant part or whole plant; (iv) subjecting the crushed or macerated plant or plant part to an extraction solvent to a sufficient period of time (e.g., 1, 5, 10, 30, or 45 minutes or more, or 1, 6, 12, or 18 hours or more, or 2, 3, 4, 5, 6 days, or more) under room temperature (e.g., 20 to 30 C.) or heated (e.g., greater than 30 C. or more, preferably 30 C. to less than the boiling point of the solvent); (v) collecting the solution comprising the extracting solvent and the extracted plant material (e.g., liquid extract); and (vi) optionally removing the extracting solvent to obtain a dried plant extract; and (vii) optionally reconstituting the dried plant extract in a liquid carrier (e.g., water, alcohol, diol, etc.). It is also contemplated in the context of the present invention that plant material from Rosmarinus officinalis leaf, Lavendula stoechas , and/or the Acmella oleracea can be directly used without subjecting the plant material to an extraction technique.

Non-limiting examples of facial muscles in which the compositions of the present invention can attenuate contraction of include facial muscles of the glabellar complex, orbicularis muscles, frontalis muscles, or depressor anguli oris muscles, or combinations thereof. The muscles of the glabellar complex can be responsible for formation of frown lines that include the corrugator supercilii, depressor supercilii, procerus, and orbicularis oculi para frontalis muscles. The corrugator supercilii lies below the frontalis muscle and functions to draw the brow medially and downward, whereas the smaller depressor supercilii can be located lower than the corrugator muscle and functions to draw the medial brow downward. The procerus can be located between the eyebrows and also works to depress the glabellar medial brow region. The depressor function of the glabellar complex is opposed by the frontalis muscle. This muscle is merged with the superior portions of the glabellar complex, from which it extends upwards underneath the forehead. The frontalis muscle is a muscle of the forehead and is associated with raising of the brow. The orbicularis muscle is a muscle that closes the eyelids. The depressor anguli oris muscle is a facial muscle associated with frowning. In a preferred aspect, contractile activity is measured.

In Vitro Myotube Contraction Data

Each of Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and Acmella oleracea extract were found to reduce contraction of myotubes, which can result in reduced muscle contraction of a facial muscle and reduced appearance of facial deep lines or wrinkles and dynamic facial wrinkles and forehead wrinkles that are caused due to repetitive facial muscle contraction. The methodology used to obtain the data included: (1) Primary Human Skeletal muscle myoblasts (HSMM) were made to differentiate into Myotubes; (2) Myotubes were then treated with inducers (Acetcholine), which in turn causes an influx of calcium and creating an action potential; and (3) This action potential causes the muscle cells to contract. The concentration amounts of each extract used and the resulting effect on inhibition of calcium levels are provided in Table 1.

Collagen is an extracellular matrix protein critical for skin structure. Increased synthesis of collagen helps improve skin firmness and elasticity. This bioassay was used to examine the effect of Acmella oleracea extract on the production of procollagen peptide (a precursor to collagen) by human dermal fibroblasts. The endpoint of this assay was a spectrophotometric measurement that reflected the presence of procollagen peptide and cellular viability. The assay employed the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for procollagen peptide was pre-coated onto a microplate. Standards and samples were pipetted into the wells and any procollagen peptide present was bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for procollagen peptide was added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution was added to the wells and color developed in proportion to the amount of procollagen peptide bound in the initial step. Color development was stopped and the intensity of the color at 450 nm was measured using a microplate reader.

For generation of samples and controls, subconfluent normal human adult dermal fibroblasts (Cascade Biologics) were cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37 C. in 10% CO 2 . The cells were treated with each of the tested ingredients and controls for 3 days. Following incubation, cell culture medium was collected and the amount of procollagen peptide secretion was quantified using the sandwich enzyme linked immuno-sorbant assay (ELISA) from Takara (# MK101) as explained above.

In Vitro Laminin Expression Data

Acmella oleracea extract was found to increase laminin production in human dermal fibroblasts. The data and amount of extract used is provided in Table 3.

TABLE 3IngredientIncreased Laminin Production Acmella Oleracea Extract*1.0 wt. % conc. = 53% increased lamininproduction* Acmella oleracea extract used was a hydro-ethanolic extract in which the solvent included a fluid mixture of water, ethanol, and 1,3 propanediol. The ethanol was removed from the resulting extraction fluid. The extract was supplied by Gattefoss (France) under the trade name GATULINE EXPRESSION AF.

Laminin is a major protein in the dermal-epidermal junction (DEJ) (also referred to as the basement membrane). The DEJ is located between the dermis and the epidermis and interlocks forming fingerlike projections called rete ridges. The cells of the epidermis receive their nutrients from the blood vessels in the dermis. The rete ridges increase the surface area of the epidermis that is exposed to these blood vessels and the needed nutrients. The DEJ provides adhesion of the two tissue compartments and governs the structural integrity of the skin. Laminin is a structural glycoproteins located in the DEJ. Considered a glue that holds the cells together, laminin is secreted by dermal fibroblasts to help facilitate intra- and inter-cellular adhesion of the epidermal cells to the DEJ. Laminin secretion was monitored by quantifying laminin in cell supernatants of cultured human fibroblasts treated for 3 days with culture medium with the test ingredient ( Acmella oleracea extract). Following incubation, laminin was measured using immunofluorescent antibodies directed against each protein in an enzyme linked immuno-sorbant assay (ELISA). Measurements were normalized for cellular metabolic activity, as determined by bioconversion of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS).

Matrix Metalloproteinase 1 Enzyme Activity (MMP-1) Assay: MMPs are extracellular proteases that play a role in many normal and disease states by virtue of their broad substrate specificity. MMP-1 substrates include collagen IV. The Molecular Probes Enz/Chek Gelatinase/ Collagenase Assay kit (# E12055) utilizes a fluorogenic gelatin substrate to detect MMP1 protease activity. Upon proteolytic cleavage, bright green fluorescence is revealed and may be monitored using a fluorescent microplate reader to measure enzymatic activity. The Enz/Chek Gelatinase/Collagenase Assay kit (# E12055) from Invitrogen is designed as an in vitro assay to measure MMP-1 enzymatic activity. The Rosmarinus officinalis leaf extract was assayed. The assay relies upon the ability of purified MMP-1 enzyme to degrade a fluorogenic gelatin substrate. Once the substrate is specifically cleaved by MMP-1 bright green fluorescence is revealed and was monitored using a fluorescent microplate reader. Rosmarinus officinalis leaf extract was incubated in the presence or absence of the purified enzyme and substrate to determine their protease inhibitor capacity.

Matrix Metalloproteinase 3 and 9 Enzyme Activity (MMP-3 and MMP-9) Assay: MMP-3 substrates include collagens, fibronectins, and laminin; while MMP-9 substrates include collagen VII, fibronectins and laminin. Using Colorimetric Drug Discovery kits from BioMol International for MMP3 (AK-400) and MMP-9 (AK-410), this assay was designed to measure protease activity of MMPs using a thiopeptide as a chromogenic substrate (Ac-PLG-[2-mercapto-4-methyl-pentanoyl]-LG-OC2H5)5,6. The MMP cleavage site peptide bond is replaced by a thioester bond in the thiopeptide. Hydrolysis of this bond by an MMP produces a sulfhydryl group, which reacts with DTNB [5,5-dithiobis(2- nitrobenzoic acid), Ellman's reagent] to form 2-nitro-5-thiobenzoic acid, which can be detected by its absorbance at 412 nm (=13,600 M-1 cm-1 at pH 6.0 and above 7). The Rosmarinus officinalis leaf extract was assayed.

The purpose of the comparative in vivo clinical study was to evaluate the efficacy of a combination of the three extracts for muscle relaxation and wrinkle reduction over four weeks of twice-daily application on Experimental Group 1 participants using a micro-roller (n=33) versus application on Experimental Group 2 participants without using a micro-roller (n=30). The combination of the three extracts was placed in a dermatologically acceptable vehicle as the test product. The dermatologically acceptable vehicle was designed to test the efficacy of the combination of the three extracts when applied with a micro-roller versus application without a micro-roller. Study participants in Experimental Group 1 used a 1.0 mm microroller. Study participants applied the composition containing the three extracts between their eyebrows in the morning and the evening after cleansing their face with a personal cleanser. For Experimental Group 1, study participants used the micro-roller 3 times per week in the evenings by rolling the micro-roller back and forth 4 to 5 times between eyebrows changing directions with each pass. For both Experimental Group 1 and Experimental Group 2, an occlusive patch (e.g., SCARAWAY) was placed between eyebrows overnight. The other ingredients in the dermatologically acceptable vehicle were not believed to contribute to the clinical data results in either a positive or negative manner. The amounts of each extract used in the dermatologically acceptable vehicle was Rosmarinus officinalis leaf extract at 1 wt. %, Lavendula stoechas extract at 2 wt. %, and Acmella oleracea extract at 2 wt. %.

The comparative in vivo clinical study design was a randomized controlled, investigator-blinded clinical study. The following parameters were used: (1) subjectsfemales between the ages of 35 and 70 in good general health (no physical required) and were clinically determined to have scored 3-7 (inclusively) on a 10-point scale for moderate frown/glabellar lines; (2) test siteglabella area; (3) test productFrontalis; supplemental productsSCARAWAY occlusive patch, and microroller; (4) evaluation time pointsbaseline (week 0), week 2, week 4, and week 8; (5) testing methodelectromyography (EMG) for muscle response (mV/s):AUC (area under the curve); and (6) clinical endpoints measuredfine lines and wrinkles and skin texture on a 0 to 9 scale.

FIGS. 7-8 provide data illustrating reduction in the appearance of fine lines and wrinkles comparing percent improvement between application with a micro-roller and application without a micro-roller. As illustrated in FIGS. 5-8, the data suggests that application of the composition containing the combination of Rosmarinus officinalis leaf extract, Lavendula stoechas extract, and Acmella oleracea extract, combined with using a micro-roller to promote penetration of the composition into the skin, can reduce facial muscle contraction and can reduce the overall appearance of fine lines and wrinkles. It was determined that application of the composition with a micro-roller was effective at attaining a faster and stronger reduction in facial muscle contraction at 2, 4, and 8 weeks compared to baseline, and reduced fine lines and wrinkles and skin texture within 4 weeks, where 79% of subjects showed improvement in both fine lines and wrinkles and skin smoothness after 8 weeks. It was further determined that application of the composition without a micro-roller was still effective at attaining a reduction in facial muscle contraction after 8 weeks, and reduced fine lines and wrinkles and skin texture within 4 weeks, where 87% of subjects showed improvement in both fine lines and wrinkles and 90% in skin smoothness after 8 weeks.

FIGS. 9-10 provide data illustrating improvement in skin texture/roughness comparing percent improvement between application with a micro-roller and application without a micro-roller.

Additional Assays

Assays that can be used to determine the efficacy of any one of the ingredients or any combination of ingredients or compositions having said combination of ingredients disclosed throughout the specification and claims can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures.

Antioxidant (AO) Assay: An in vitro bioassay that measures the total anti-oxidant capacity of any one of the ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification. The assay relies on the ability of antioxidants in the sample to inhibit the oxidation of ABTS (2,2-azino-di-[3-ethylbenzthiazoline sulphonate]) to ABTS+ by metmyoglobin. The antioxidant system of living organisms includes enzymes such as superoxide dismutase, catalase, and glutathione peroxidase; macromolecules such as albumin, ceruloplasmin, and ferritin; and an array of small molecules, including ascorbic acid, -tocopherol, -carotene, reduced glutathione, uric acid, and bilirubin. The sum of endogenous and food-derived antioxidants represents the total antioxidant activity of the extracellular fluid. Cooperation of all the different antioxidants provides greater protection against attack by reactive oxygen or nitrogen radicals, than any single compound alone. Thus, the overall antioxidant capacity may give more relevant biological information compared to that obtained by the measurement of individual components, as it considers the cumulative effect of all antioxidants present in plasma and body fluids. The capacity of the antioxidants in the sample to prevent ABTS oxidation is compared with that of Trolox, a water-soluble tocopherol analogue, and is quantified as molar Trolox equivalents. Anti-Oxidant capacity kit #709001 from Cayman Chemical (Ann Arbor, Mich. USA) can be used as an in vitro bioassay to measure the total anti-oxidant capacity of each of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification. The protocol can be followed according to manufacturer recommendations.

ORAC Assay: Oxygen Radical Absorption (or Absorbance) Capacity (ORAC) of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification can also be assayed by measuring the antioxidant activity of such ingredients or compositions. Antioxidant activity indicates a capability to reduce oxidizing agents (oxidants). This assay quantifies the degree and length of time it takes to inhibit the action of an oxidizing agent, such as oxygen radicals, that are known to cause damage to cells (e.g., skin cells). The ORAC value of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification can be determined by methods known to those of ordinary skill in the art (see U.S. Publication Nos. 2004/0109905 and 2005/0163880; and commercially available kits such as Zen-Bio ORAC Anti-oxidant Assay kit (# AOX-2)). The Zen-Bio ORAC Anti-oxidant Assay kit measures the loss of fluorescein fluorescence over time due to the peroxyl-radical formation by the breakdown of AAPH (2,2-axobis-2-methyl propanimidamide, dihydrochloride). Trolox, a water soluble vitamin E analog, serves as positive control inhibition fluorescein decay in a dose dependent manner.

Cyclooxygenase (COX) Assay: An in vitro cyclooxygenase-1 and -2 (COX-1, -2) inhibition assay. COX is a bifunctional enzyme exhibiting both cyclooxygenase and peroxidase activities. The cyclooxygenase activity converts arachidonic acid to a hydroperoxy endoperoxide (Prostaglandin G2; PGG2) and the peroxidase component reduces the endoperoxide (Prostaglandin H2; PGH2) to the corresponding alcohol, the precursor of prostaglandins, thromboxanes, and prostacyclins. This COX Inhibitor screening assay measures the peroxidase component of cyclooxygenases. The peroxidase activity is assayed colorimetrically by monitoring the appearance of oxidized N,N,N,N-tetramethyl-p-phenylenediamine (TMPD). This inhibitor screening assay includes both COX-1 and COX-2 enzymes in order to screen isozyme-specific inhibitors. The Colormetric COX (ovine) Inhibitor screening assay (#760111, Cayman Chemical) can be used to analyze the effects of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification on the activity of purified cyclooxygenase enzyme (COX-1 or COX-2). According to manufacturer instructions, purified enzyme, heme and test extracts can be mixed in assay buffer and incubated with shaking for 15 min at room temperature. Following incubation, arachidonic acid and colorimetric substrate can be added to initiate the reaction. Color progression can be evaluated by colorimetric plate reading at 590 nm. The percent inhibition of COX-1 or COX-2 activity can be calculated compared to non-treated controls to determine the ability of test extracts to inhibit the activity of purified enzyme.

Lipoxygenase (LO) Assay: An in vitro lipoxygenase (LO) inhibition assay. LOs are non-heme iron-containing dioxygenases that catalyze the addition of molecular oxygen to fatty acids. Linoleate and arachidonate are the main substrates for LOs in plants and animals. Arachidonic acid may then be converted to hydroxyeicosotrienenoic (HETE) acid derivatives, that are subsequently converted to leukotrienes, potent inflammatory mediators. This assay provides an accurate and convenient method for screening lipoxygenase inhibitors by measuring the hydroperoxides generated from the incubation of a lipoxygenase (5-, 12-, or 15-LO) with arachidonic acid. The Colorimetric LO Inhibitor screening kit (#760700, Cayman Chemical) can be used to determine the ability of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification to inhibit enzyme activity. Purified 15-lipoxygenase and test ingredients can be mixed in assay buffer and incubated with shaking for 10 min at room temperature. Following incubation, arachidonic acid can be added to initiate the reaction and the mixtures can be incubated for an additional 10 min at room temperature. Colorimetric substrate can be added to terminate catalysis and color progression can be evaluated by fluorescence plate reading at 490 nm. The percent inhibition of lipoxyganse activity can be calculated compared to non-treated controls to determine the ability of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification to inhibit the activity of purified enzyme.

B16 Pigmentation Assay: Melanogenesis is the process by which melanocytes produce melanin, a naturally produced pigment that imparts color to skin, hair, and eyes. Inhibiting melanogenesis is beneficial to prevent skin darkening and lighten dark spots associated with aging. This bioassay utilizes B16-F1 melanocytes (ATCC), an immortalized mouse melanoma cell line, to analyze the effect of compounds on melanogenesis. The endpoint of this assay is a spectrophotometric measurement of melanin production and cellular viability. B16-F1 melanocytes can be cultivated in standard DMEM growth medium with 10% fetal bovine serum (Mediatech) at 37 C. in 10% CO 2 and then treated with any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification for 6 days. Following incubation, melanin secretion is measured by absorbance at 405 nm and cellular viability was quantified.

Elastin Stimulation Assay: Elastin is a connective tissue protein that helps skin resume shape after stretching or contracting. Elastin is also an important load-bearing protein used in places where mechanical energy is required to be stored. Elastin is made by linking many soluble tropoelastin protein molecules, in a reaction catalyzed by lysyl oxidase. Elastin secretion and elastin fibers can be monitored in cultured human fibroblasts by staining of cultured human fibroblasts using immunofluorescent antibodies directed against elastin.

Laminin and Fibronectin Stimulation Assay: Laminin and fibronectin are major proteins in the dermal-epidermal junction (DEJ) (also referred to as the basement membrane). The DEJ is located between the dermis and the epidermis and interlocks forming fingerlike projections called rete ridges. The cells of the epidermis receive their nutrients from the blood vessels in the dermis. The rete ridges increase the surface area of the epidermis that is exposed to these blood vessels and the needed nutrients. The DEJ provides adhesion of the two tissue compartments and governs the structural integrity of the skin. Laminin and fibronectin are two structural glycoproteins located in the DEJ. Considered the glue that holds the cells together, laminin and fibronectin are secreted by dermal fibroblasts to help facilitate intra- and inter-cellular adhesion of the epidermal cells to the DEJ. Laminin and fibronectin secretion can be monitored by quantifying laminin and fibronectin in cell supernatants of cultured human fibroblasts treated for 3 days with culture medium with or without the test ingredient(s). Following incubation, laminin and fibronectin content can be measured using immunofluorescent antibodies directed against each protein in an enzyme linked immuno-sorbant assay (ELISA). Measurements are normalized for cellular metabolic activity, as determined by bioconversion of 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS).

Tumor Necrosis Factor Alpha (TNF-) Assay: The prototype ligand of the TNF superfamily, TNF-, is a pleiotropic cytokine that plays a central role in inflammation. Increase in its expression is associated with an up regulation in pro-inflammatory activity. This bioassay can be used to analyze the effect of any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification on the production of TNF- by human epidermal keratinocytes. The endpoint of this assay can be a spectrophotometric measurement that reflects the presence of TNF- and cellular viability. The assay employs the quantitative sandwich enzyme immunoassay technique whereby a monoclonal antibody specific for TNF- has been pre-coated onto a microplate. Standards and samples can be pipetted into the wells and any TNF- present is bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked polyclonal antibody specific for TNF- can be added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution can be added to the wells and color developed in proportion to the amount of TNF- bound in the initial step using a microplate reader for detection at 450 nm. The color development can be stopped and the intensity of the color can be measured. Subconfluent normal human adult keratinocytes (Cascade Biologics) cultivated in EPILIFE standard growth medium (Cascade Biologics) at 37 C. in 5% CO 2 , can be treated with phorbol 12-myristate 13-acetate (PMA, 10 ng/ml, Sigma Chemical, # P1585-1MG) and any one of the active ingredients, combination of ingredients, or compositions having said combinations disclosed in the specification for 6 hours. PMA has been shown to cause a dramatic increase in TNF- secretion which peaks at 6 hours after treatment. Following incubation, cell culture medium can be collected and the amount of TNF- secretion quantified using a sandwich enzyme linked immuno-sorbant assay (ELISA) from RD Systems (# DTA00C).

Mushroom tyrosinase activity assay: In mammalian cells, tyrosinase catalyzes two steps in the multi-step biosynthesis of melanin pigments from tyrosine (and from the polymerization of dopachrome). Tyrosinase is localized in melanocytes and produces melanin (aromatic quinone compounds) that imparts color to skin, hair, and eyes. Purified mushroom tyrosinase (Sigma) can be incubated with its substrate L-Dopa (Fisher) in the presence or absence of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. Pigment formation can be evaluated by colorimetric plate reading at 490 nm. The percent inhibition of mushroom tyrosinase activity can be calculated compared to non-treated controls to determine the ability of test ingredients or combinations thereof to inhibit the activity of purified enzyme. Test extract inhibition can be compared with that of kojic acid (Sigma).

Elastase Assay: ENZCHEK Elastase Assay (Kit # E-12056) from Molecular Probes (Eugene, Oreg. USA) can be used as an in vitro enzyme inhibition assay for measuring inhibition of elastase activity for each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. The EnzChek kit contains soluble bovine neck ligament elastin that can be labeled with dye such that the conjugate's fluorescence can be quenched. The non-fluorescent substrate can be digested by elastase or other proteases to yield highly fluorescent fragments. The resulting increase in fluorescence can be monitored with a fluorescence microplate reader. Digestion products from the elastin substrate have absorption maxima at 505 nm and fluorescence emission maxima at 515 nm. The peptide, N-methoxysuccinyl-Ala-Ala-Pro-Val-chloromethyl ketone, can be used as a selective, collective inhibitor of elastase when utilizing the EnzChek Elastase Assay Kit for screening for elastase inhibitors.

Oil Control Assay: An assay to measure reduction of sebum secretion from sebaceous glands and/or reduction of sebum production from sebaceous glands can be assayed by using standard techniques known to those having ordinary skill in the art. In one instance, the forehead can be used. Each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be applied to one portion of the forehead once or twice daily for a set period of days (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or more days), while another portion of the forehead is not treated with the composition. After the set period of days expires, then sebum secretion can be assayed by application of fine blotting paper to the treated and untreated forehead skin. This is done by first removing any sebum from the treated and untreated areas with moist and dry cloths. Blotting paper can then be applied to the treated and untreated areas of the forehead, and an elastic band can be placed around the forehead to gently press the blotting paper onto the skin. After 2 hours the blotting papers can be removed, allowed to dry and then transilluminated. Darker blotting paper correlates with more sebum secretion (or lighter blotting paper correlates with reduced sebum secretion.

Erythema Assay: An assay to measure the reduction of skin redness can be evaluated using a Minolta Chromometer. Skin erythema may be induced by applying a 0.2% solution of sodium dodecyl sulfate on the forearm of a subject. The area is protected by an occlusive patch for 24 hrs. After 24 hrs, the patch is removed and the irritation-induced redness can be assessed using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. Immediately after reading, the area is treated with the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification. Repeat measurements can be taken at regular intervals to determine the formula's ability to reduce redness and irritation.

Skin Moisture/Hydration Assay: Skin moisture/hydration benefits can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72 C.). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance. Each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be assayed according to this process.

Skin Clarity and Reduction in Freckles and Age Spots Assay: Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a 2 +b 2 ) 1/2 .

Skin Dryness, Surface Fine Lines, Skin Smoothness, and Skin Tone Assay: Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.

Clinical Grading of Skin Tone Assay: Clinical grading of skin tone can be performed via a ten point analog numerical scale: (10) even skin of uniform, pinkish brown color. No dark, erythremic, or scaly patches upon examination with a hand held magnifying lens. Microtexture of the skin very uniform upon touch; (7) even skin tone observed without magnification. No scaly areas, but slight discolorations either due to pigmentation or erythema. No discolorations more than 1 cm in diameter; (4) both skin discoloration and uneven texture easily noticeable. Slight scaliness. Skin rough to the touch in some areas; and (1) uneven skin coloration and texture. Numerous areas of scaliness and discoloration, either hypopigmented, erythremic or dark spots. Large areas of uneven color more than 1 cm in diameter. Evaluations were made independently by two clinicians and averaged.

Clinical Grading of Skin Smoothness Assay: Clinical grading of skin smoothness can be analyzed via a ten point analog numerical scale: (10) smooth, skin is moist and glistening, no resistance upon dragging finger across surface; (7) somewhat smooth, slight resistance; (4) rough, visibly altered, friction upon rubbing; and (1) rough, flaky, uneven surface. Evaluations were made independently by two clinicians and averaged.

Skin Smoothness and Wrinkle Reduction Assay With Methods Disclosed in Packman et al. (1978): Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman et al. (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.

Skin Firmness Assay with a Hargens Ballistometer: Skin firmness can be measured using a Hargens ballistometer, a device that evaluates the elasticity and firmness of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.

Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer: Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).

Appearance of Lines and Wrinkles Assay with Replicas: The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and are of the replicas covered by wrinkles or fine lines was determined.

Surface Contour of the Skin Assay with a Profilometer/Stylus Method: The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: R a =Standardize roughness; l m =the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height (x-axis).

MELANODERM Assay: In other non-limiting aspects, the efficacy of each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be evaluated by using a skin analog, such as, for example, MELANODERM. Melanocytes, one of the cells in the skin analog, stain positively when exposed to L-dihydroxyphenyl alanine (L-DOPA), a precursor of melanin. The skin analog, MELANODERM, can be treated with a variety of bases containing each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification or with the base alone as a control. Alternatively, an untreated sample of the skin analog can be used as a control.

Production of Filaggrin: Changes in the production of filaggrin in keratinocytes due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Filaggrin is the precursor to Natural Moisturizing Factor (NMF) in the skin. Increased NMF increases the moisture content of the skin. Filaggrin production in treated and non-treated keratinocytes can be determined using a bioassay that analyzes filaggrin concentration in keratinocyte cell lysates. A non-limiting example of a bioassay that can be used to quantify filaggrin production is the PROTEINSIMPLE SIMON western blotting protocol. For each sample, normal human epidermal keratinocytes (NHEK) are grown in EPI-200-Mattek EPILIFE growth media with calcium from Life Technologies (M-EP-500-CA). NHEK are incubated in growth medium overnight at 37 C. in 5% CO 2 prior to treatment. NHEK are then incubated in growth medium with 1% test compound/extract or no compound/extract (negative control) for 24 to 36 hours. The NHEK can then be washed, collected, and stored on ice or colder until lysed on ice using a lysis buffer and sonication. The protein concentrations of the samples can be determined and used to normalize the samples. The lysates can be stored at 80 C. until use in the quantification assay.

The PROTEINSIMPLE SIMON western blotting bioassay assay employs a quantitative western blotting immunoassay technique using an antibody specific for filaggrin to quantitatively detect filaggrin in the test samples. Cell samples are lysed and normalized for protein concentration. Normalized samples and molecular weight standards can then be loaded and ran on a denatured protein separation gel using capillary electrophoresis. The proteins in the gel are immobilized and immunoprobed using a primary antibody specific for filaggrin. The immobilized proteins can then be immunoprobed with an enzyme-linked detection antibody that binds the primary antibody. A chemiluminescent substrate solution can then be added to the immobilized proteins to allow chemiluminescent development in proportion to the amount of filaggrin bound in the immobilization. The chemiluminescent development is stopped at a specific time and the intensity of the chemiluminescent signal can be measured and compared to positive and negative controls.

Production of Occludin: Changes in the production of occludin in keratinocytes due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Occludin is a protein critical to the formulation of tight junctions and the skin's moisture barrier function. A non-limiting example of how occludin production in treated and non-treated keratinocytes can be determined is by the use of a bioassay that analyzes occludin concentration in keratinocyte cell lysates. The bioassay can be performed using PROTEINSIMPLE SIMON western blotting protocol. For the samples, adult human epidermal keratinocytes (HEKa) from Life Technologies (C-005-5C) can be grown at 37 C. and 5% CO2 for 24 hours in EPILIFE growth media with calcium from Life Technologies (M-EP-500-CA) supplemented with Keratinocyte Growth Supplement (HKGS) from Life Technologies (S-101-5). HEKa are then incubated in growth medium with test compound/extract, no compound/extract for negative control, or with 1 mM CaCl 2 for positive control for 24 to 48 hours. The HEKa are then washed, collected, and stored on ice or colder until lysed on ice using a lysis buffer and sonication. The protein concentrations of the samples can be determined and used to normalize the samples. The lysates are stored at 80 C. until use in the bioassay.

The chemiluminescent development can be stopped at a specific time and the intensity of the chemiluminescent signal can be measured and compared to positive and negative controls.

Keratinocyte Monolayer Permeability: Changes in the permeability of a keratinocyte monolayer due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Keratinocyte monolayer permeability is a measure of skin barrier integrity. Keratinocyte monolayer permeability in treated and non-treated keratinocytes can be determined using, as a non-limiting example, the In Vitro Vascular Permeability assay by Millipore (ECM642). This assay analyzes endothelial cell adsorption, transport, and permeability. Briefly, adult human epidermal keratinocytes from Life Technologies (C-005-5C) can be seeded onto a porous collagen-coated membrane within a collection well. The keratinocytes are then incubated for 24 hours at 37 C. and 5% CO 2 in EPILIFE growth media with calcium from Life Technologies (M-EP-500-CA) supplemented with Keratinocyte Growth Supplement (HKGS) from Life Technologies (S-101-5). This incubation time allows the cells to form a monolayer and occlude the membrane pores. The media is then replaced with fresh media with (test sample) or without (non-treated control) test compounds/extracts and the keratinocytes are incubated for an additional 48 hours at 37 C. and 5% CO 2 . To determine permeability of the keratinocyte monolayer after incubation with/without the test compound/extract, the media is replaced with fresh media containing a high molecular weight Fluorescein isothiocyanate (FITC)-Dextran and the keratinocytes are incubated for 4 hours at 37 C. and 5% CO 2 . During the 4 hours incubation, FITC can pass through the keratinocytes monolayer and porous membrane into the collection well at a rate proportional to the monolayer's permeability. After the 4 hour incubation, cell viability and the content of FITC in the collection wells can be determined. For the FITC content, the media in the collection well is collected and fluorescence of the media determined at 480 nm (Em) when excited at 520 nm. Percent permeability and percent change in comparison to the non-treated controls can be determined by the following equations: Percent Permeability=((Mean Ex/Em of test sample)/Mean Ex/Em untreated control)*100; Percent Change=Percent Permeability of test samplePercent Permeability of untreated control.

Production of Hyaluronic Acid: Changes in the production of hyaluronic acid in human dermal fibroblasts due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. HA is a polysaccharide involved in stabilization of the structure of the matrix and is involved in providing turgor pressure to tissue and cells. As one non-limiting example, HA production in treated and non-treated adult human dermal fibroblasts (HDFa) cells can be determined using the Hyaluronan DuoSet ELISA kit from RD Systems (DY3614). In this assay, for production of samples, subconfluent HDFa cells from Cascade Biologics (C-13-5C) are incubated at 37 C. and 10% CO 2 in starvation medium (0.15% fetal bovine serum and 1% Penicillin Streptomycin solution in Dulbecco's Modified Eagle Medium) for 72 hours prior to treatment. The cells are then incubated with fresh starvation medium with either test compound, positive control (phorbol 12-myristate 13-acetate from Sigma-Aldrich (P1585) and platelet derived growth factor from Sigma-Aldrich (P3201)), or no additive for 24 hours. Media is then collected and frozen at 80 C. until use in the ELISA assay.

Briefly, the ELISA assay employs a quantitative sandwich enzyme immunoassay technique whereby a capture antibody specific for HA can be pre-coated onto a microplate. Standards and media from treated and untreated cells are pipetted into the microplate wells to enable any HA present to be bound by the immobilized antibody. After washing away any unbound substances, an enzyme-linked detection antibody specific for HA is added to the wells. Following a wash to remove any unbound antibody-enzyme reagent, a substrate solution is added to the wells to allow color development in proportion to the amount of HA bound in the initial step. The color development is stopped at a specific time and the intensity of the color at 450 nm can be measured using a microplate reader.

Inhibition of Hyaluronidase Activity: Changes in the activity of hyaluronidase due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. Hyaluronidase is an enzyme that degrades HA. HA is a polysaccharide involved in stabilization of the structure of the matrix and is involved in providing turgor pressure to tissue and cells. As one non-limiting example, hyaluronidase activity can be determined using an in vitro protocol modified from Sigma-Aldrich protocol # EC 3.2.1.35. Briefly, hyaluronidase type 1-S from Sigma-Aldrich (H3506) is added to microplate reaction wells containing test compound or controls. Tannic acid can be used as a positive control inhibitor, no test compound can be added for the control enzyme, and wells with test compound or positive control but without hyaluronidase can be used as a background negative control. The wells are incubated at 37 C. for 10 minutes before addition of substrate (HA). Substrate is added and the reactions incubated at 37 C. for 45 minutes. A portion of each reaction solution is then transferred to and gently mixed in a solution of sodium acetate and acetic acid pH 3.75 to stop that portion of the reaction (stopped wells). The stopped wells and the reaction wells should both contain the same volume of solution after addition of the portion of the reaction solution to the stopped wells. Both the reaction wells and the stopped wells are incubated for 10 minutes at room temperature. Absorbance at 600 nm is then measured for both the reaction wells and the stopped wells. Inhibition can be calculated using the following formulas: Inhibitor (or control) activity=(Inhibitor stopped wells absorbance at 600 nminhibitor reaction wells absorbance at 600 nm); Initial activity =control enzyme absorbance at 600 nm; Percent Inhibition=[(Initial activity/Inhibitor Activity)*100]-100.

Peroxisome Proliferator-Activated Receptor Gamma (PPAR-) Activity: Changes in the activity of PPAR- due to each of the active ingredients, any one of the combination of ingredients, or compositions having said combinations disclosed in the specification can be measured. PPAR- is a receptor critical for the production of sebum. As one non-limiting example, the activity of PPAR- can be determined using a bioassay that analyzes the ability of a test compound or composition to inhibit binding of a ligand. Briefly, fluorescent small-molecule pan-PPAR ligand, FLUORMONE Pan-PPAR Green, available from Life Technologies (PV4894), can be used to determine if test compounds or compositions are able to inhibit binding of the ligand to PPAR-. The samples wells include PPAR-y and fluorescent ligand and either: test compound or composition (test); a reference inhibitor, rosiglitazone (positive control); or no test compound (negative control). The wells are incubated for a set period of time to allow the ligand opportunity to bind the PPAR-. The fluorescence polarization of each sample well can then be measured and compared to the negative control well to determine the percentage of inhibition by the test compound or composition.

Cytokine array: Human epidermal keratinocytes are cultured to 70-80% confluency. The media in the plate is aspirated and 0.025% trypsin/EDTA is added. When the cells became rounded, the culture dish is gently tapped to release the cells. The trypsin/EDTA containing cells are removed from the culture dish and neutralized. Cells are centrifuged for 5 min. at 180 g to form a pellet of cells. The supernatant is aspirated. The resulting pellet is resuspended in EPILIFE media (Cascade Biologics). The cells are seeded in 6-well plates at approximately 10-20% confluency. After the cells became approximately 80% confluent, the media is aspirated and 1.0 ml of EPILIFE, along with phorbol 13-Myristate 12-acetate (PMA) (a known inducer of inflammation) and the test composition dilutions are added to two replicate wells (i.e., 1.0% (100 l of 100 stock) and 0.1% (10 l of 100 stock) test compositions are diluted into a final volume of 1 ml EPILIFE Growth Medium). The media is gently swirled to ensure adequate mixing. In addition, 1.0 ml of EPILIFE is added to the control wells, with and without additional PMA. The plates are then incubated at 371 C. and 5.01% CO 2 for approximately 5 hours after dosing. Following this 5-hour incubation, all media is collected in conical tubes and frozen at 70 C.

For analysis, a 16-pad hybridization chamber is attached to 16-pad FAST slides arrayed in triplicate with 16 anti-cytokine antibodies plus experimental controls (Whatman BioSciences), and the slides are placed into a FASTFrame (4 slides per frame) for processing. Arrays are blocked for 15 min. at room temp. using 70 ml SS Protein Array Blocking buffer (Whatman Schleicher and Scheull). Blocking buffer is removed and 70 ml of each supernatant sample is added to each array. Arrays are incubated for 3 hours at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T. Arrays are treated with 70 ml of an antibody cocktail, containing one biotinylated antibody corresponding to each of the arrayed capture antibodies. Arrays are incubated for 1 hour at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T. Arrays are incubated with 70 ml of a solution containing streptavidin-Cy5 conjugate for 1 hour at room temp. with gentle agitation. Arrays are washed 3 times with TBS-T, quickly rinsed in deionized water, and dried.

Slides can be imaged in a Perkin-Elmer ScanArray 4000 confocal fluorescent imaging system. Array images can be saved and analyzed using Imaging Research ArrayVision software. Briefly, spot intensities are determined by subtracting background signal. Spot replicates from each sample condition can be averaged and then compared to the appropriate controls.

Endothelial Tube Formation: Endothelial tube formation is involved in angiogenesis and micro-vessel capillary formation. Capillary formation and angiogenesis may contribute to redness and rosacea of the skin. The ability for endothelial cells to form tubes in the presence or absence of test extracts and compounds may be determined using a capillary tubule disruption assay with pre-formed primary human umbilical vein endothelial cells (HUVEC) in a cell culture system.

Briefly, HUVECs are cultured in vitro on Extracellular Matrix, which stimulates the attachment and tubular morphogenesis of endothelial cells to form capillary-like lumen structures. These in vitro formed capillary tubules are similar to human blood vessel capillaries in many aspects. The capillary tube assay is based on this phenomenon and is used for evaluation of potential vasculature targeting agents.

HUVEC cultures are grown in a 5% CO 2 37 C. cell incubator. The full growth medium for HUVECs is Endothelial Cell Basal Medium (EBM) supplemented with 2% fetal bovine serum (FBS), 12 g /ml bovine brain extract, 1 g/ml hydrocortisone, and 1 g/ml GA-1000 (gentamicin-amphothericin). HUVEC cultures between passage 3 and 8 may be used for all assay experiments.

HUVECs are pre-labeled with fluorescent agent Calcein AM and seeded in Extracellular Matrix coated 96-well culture plate with their full growth medium. After about four hours of the morphogenesis process, the endothelial capillary tubes should be formed. Then, test agent in designed doses in 50 l volume is applied into the formed capillary tubule cultures as treatment conditions. The no-treatment controls can be added with vehicle of test agents. Sutent, a FDA approved anti-angiogenic drug one concentration can be included as assay performance control. After about six hours of treatment, the endothelial tubule morphology in each well is examined by microscopy, imaged, and the capillary disrupting activities under treatment conditions can be quantitatively analyzed. Each test conditions can be conducted in duplicate wells, including controls.
