Description

[0001] COSMETIC COMPOSITION

[0002] Technical Field of the Invention

[0003] The present invention relates to a cosmetic composition and the use of the cosmetic composition for improving aging attributes.

[0004] Background to the Invention

[0005] Skin forms the barrier between the outside world and the human body and as a person ages, the skin ages. Skin can age through a number of mechanisms including oxidative stress, cellular senescence, and DNA damage for example by ultraviolet radiation or pollution.

[0006] The physical attributes of aging skin may be defined as skin firmness, skin surface consistency, skin glow and skin tone consistency. Skin surface consistency includes the appearance of pores, wrinkles, fine lines and deep wrinkles. Skin glow refers to the overall appearance of the skin including descriptors such as radiance, brightness, vibrancy, and complexion. Deterioration of these attributes may lead to visibly aged skin. It would therefore be advantageous to provide a cosmetic composition which may slow, prevent or reverse negative aging skin attributes with improved efficacy. It would be advantageous to provide a cosmetic composition which may slow, prevent or reverse negative aging skin attributes with improved efficacy.

[0007] Cosmetics such as face creams, gels or lotions may be used to reduce or prevent the physical attributes of aging skin. Known cosmetics typically comprise a large number of active ingredients which can lead to expensive products with complex manufacturing methods. It would therefore be advantageous to provide a cosmetic composition which comprises fewer ingredients such that it is easier to manufacture and is cheaper to produce. It would be advantageous to provide a cosmetic composition which is easier to manufacture and results in no loss of anti-aging performance efficacy or preferably improved efficacy.

[0008] It would furthermore be advantageous to mitigate or overcome at least one problem of the prior art, whether disclosed herein or not.

[0009] Summary of the Invention

[0010] According to a first aspect of the invention there is provided a cosmetic composition comprising between 0.5 wt.% and 5 wt.% curcumin and between 0.5 wt.% and 5 wt.% quercetin.

[0011] The cosmetic composition of the first aspect of the invention may be advantageous because it may reverse or slow the physical signs of skin aging of the user. The cosmetic composition may be advantageous because it may reverse or reduce the appearance of wrinkles, fine lines, deep wrinkles, pigmentation and / or scarring thereby creating to the appearance of more youthful skin. The cosmetic composition may be advantageous because it may improve the firmness, radiance and / or complexion of the skin thereby creating the appearance of more youthful skin.

[0012] It has surprisingly been found that combining curcumin and quercetin in the claimed amounts, in a cosmetic composition, provides significant anti-aging efficacy, compared to compositions which do not include the two ingredients in the claimed ranges. In particular, it has been surprisingly found that a combination of the two ingredients in the claimed ranges provides more than an additive effect compared to the individual ingredients and provides a superior effect compared to lower quantities of either ingredient, or lower quantities of the combined ingredients. The cosmetic composition may be a senolytic cosmetic composition. Senolytic cosmetic compositions may be advantageous because senescent cells (cells that are damaged or “aged” but do not undergo cell death) have especially deleterious effects on the tissues in which they reside; therefore, efforts to promote autophagy and the apoptotic clearance of these senescent cells through senolytic compositions have the potential to drastically improve skin quality and skin health and therefore slow, prevent or reverse negative aging skin attributes. The senolytic cosmetic composition comprising between 0.5 wt.% and 5 wt.% curcumin may be advantageous because curcumin has been shown to have senolytic properties at these concentrations which lead to an improved aging skin appearance. The senolytic cosmetic composition comprising between 0.5 wt.% and 5 wt.% quercetin may be advantageous because quercetin has been shown to have senolytic properties at these concentrations which lead to an improved aging skin appearance.

[0114] Figure 3 shows 3 graphs indicating the mean change of the appearance of wrinkles after the 2 weeks of application of a cosmetic composition (composition A) comprising 1 wt.% quercetin and 1 wt.% curcumin (A) and two weeks of applying the composition followed by a 1 week posttrial washout period (day 21) (B) and a graph comparing the appearance of wrinkles at day 15 and day 21 of the trial (C) (error bars indicate mean ± SEM).

[0115] Figure 4 shows 3 graphs indicating the mean change of the appearance of wrinkles after the 2 weeks of application of a cosmetic composition (composition B) comprising 1 wt.% quercetin, 1 wt.% curcumin and 10 wt.% rose water (A) and two weeks of applying the composition followed by a 1 week post- trial washout period (day 21) (B) and a graph comparing the appearance of wrinkles at day 15 and day 21 of the trial (C) (error bars indicate mean ± SEM).

[0116] Figure 5 shows 6 graphs indicating the change of 6 skin attributes after 1 week of topical application of a comparison cosmetic composition wherein the cosmetic composition comprises 0.0013 wt.% quercetin and 0.0013 wt.% curcumin and the skin attributes are (A) wrinkles, (B) deep wrinkles, (C) fine lines, (D) radiance, (E) pore quality and (F) pigmentation.

[0117] Figure 6 shows 6 graphs indicating the change of 6 skin attributes after 2 weeks of topical application of a comparison cosmetic composition wherein the cosmetic composition comprises 0.0013 wt.% quercetin and 0.0013 wt.% curcumin and the skin attributes are (A) wrinkles, (B) deep wrinkles, (C) fine lines, (D) radiance, (E) pore quality and (F) pigmentation.

[0118] Figure 7 shows 6 graphs indicating the change of 6 skin attributes after 2 weeks of topical application of a comparison cosmetic composition wherein the cosmetic composition comprises 0.15 wt.% quercetin and 0.15 wt.% curcumin and the skin attributes are (A) wrinkles, (B) deep wrinkles, (C) fine lines, (D) radiance, (E) pore quality and (F) pigmentation. Example 1

[0119] A first embodiment of a cosmetic composition of the first aspect of the invention is provided wherein the cosmetic composition comprises 1 wt.% quercetin, 1 wt.% curcumin, 50 wt.% aloe vera gel, 30 wt.% honey, 10 wt.% rose water, 3 wt.% grapeseed oil and 5 wt.% rice flower.

[0120] The cosmetic composition was applied to 7 participants and a number of skin attributes were measured using L’Oreal Skin Genius® analyses (https: / / www.loreal- paris.co . uk / skin- genius) . The attributes were wrinkles, radiance, firmness, pore quality, pigmentation, fine lines and deep wrinkles. The higher the rating, the more improved the attribute for example a higher rated wrinkles attribute means fewer wrinkles were observed.

[0121] The participants applied the cosmetic composition to the face twice a day (in the morning and the evening) and a photograph was taken each morning. The results of the rating of the skin attributes are displayed in the graphs of figure 1 for day 0 and day 8 and figure 2 for day 0 and day 15. The average percentage change in L’Oreal Skin

[0122] Genius® scores across the attributes of skin aging measured between day 0 and day 15 as it pertains to a first embodiment of a cosmetic composition of the first aspect are shown in table 1.

[0123] Table 1

[0124] *p<0.05, ns = not significant

[0125] These results indicated a significant improvement in radiance, pore quality, pigmentation, and fine lines after 1 week of cosmetic composition administration, with a non-significant improvement in wrinkles and deep wrinkles. After 2 weeks of administration, there was a significant improvement in wrinkles and deep wrinkles as well as radiance, pore quality, pigmentation, and fine lines.

[0126] Example 2

[0127] A second embodiment of a cosmetic composition of the first aspect of the invention (composition A) is provided wherein the cosmetic composition comprises 1 wt.% quercetin, 1 wt.% curcumin, 93 wt.% aloe gel and 5 wt.% rice flower. The cosmetic composition does not comprise 10 wt.% rose water.

[0128] A third embodiment of a cosmetic composition of the first aspect of the invention (composition B) is provided wherein the cosmetic composition comprises 1 wt.% quercetin, 1 wt.% curcumin, 10 wt.% rose water, 83 wt.% aloe gel and 5 wt.% rice flower.

[0129] Composition A and composition B were tested on participants who applied the cosmetic composition to the face twice a day (in the morning and the evening) for 2 weeks. The appearance of wrinkles was measured after two weeks of application of the compositions (day 15). Following the 2 week trial, participants undertook a 1 week post-trial washout period wherein the participants did not apply either formulation to determine the lasting effects of each of the cosmetic compositions. The appearance of wrinkles was measured after the 1 week post-trial washout period (day 21).

[0130] The average percentage change in L’ Oreal Skin Genius® scores after two weeks of applying composition A (day 15) and after two weeks of applying composition A and a 1 week post- trial washout period (day 21) and are displayed in the graphs of figure 3A and 3B respectively. Figure 3C displays a graph showing the comparison between the day 15 and the day 21 data for composition A.

[0131] The average percentage change in L’ Oreal Skin Genius® scores after two weeks of applying composition B (day 15) and after two weeks of applying composition B and a 1 week post- trial washout period (day 21) and are displayed in the graphs of figure 4A and 4B respectively. Figure 4C displays a graph showing the comparison between the day 15 and the day 21 data for composition B.

[0132] The data in figure 3A and 4A show that the appearance of wrinkles is significantly improved by each formulation after 2 weeks of twice daily administration.

[0133] The data in figure 3B and 4B also show that the appearance of wrinkles is significantly improved by each formulation after 2 weeks of twice daily administration and 1 week of post-trial washout when the data is compared to the day 0 data.

[0134] The data in figure 3C and 4C shows that formulation B, which comprises 10 wt.% rose water in addition to the 1 wt.% curcumin and 1 wt.% quercetin, provides a lasting effect, preventing a decline in the appearance of wrinkles even after the twice daily application has been stopped. It is therefore believed that rose water provides an additive effect when used in conjunction with curcumin and quercetin. The reduction in the decline in the appearance of wrinkles is advantageous because should the consumer not apply the cosmetic composition for a period of time, they would maintain the improved of skin aging attributes without significant decline.

[0135] A first embodiment of a topical cosmetic composition of the second aspect of the invention is provided wherein the topical cosmetic composition comprises 1 wt.% quercetin phytosome, 1 wt.% of a mixture of curcuminoids, 50 wt.% aloe vera gel, 30 wt.% honey, 10 wt.% rose water, 3 wt.% grapeseed oil and 5 wt.% rice flower, herein the mixture of curcuminoids comprises 75-80 wt.% of tetrahydrocurdrocurcuminoids (THC), 15-20 wt.% of hexahydrocurcuminoids (HHC) and 3-5 wt.% of octahydrocurcuminoids (OHC).

[0136] The topical cosmetic composition demonstrated the same performance as the first embodiment of the first aspect of the invention. The first embodiment of the topical cosmetic composition is advantageous because it improves the appearance of skin aging attributes and because it has a high absorption rate. comparison, two control cosmetic compositions comprising a reduced amount of curcumin and quercetin were prepared. A first control cosmetic composition sample was prepared wherein the control cosmetic composition comprises 0.0013 wt.% quercetin, 0.0013 wt.% curcumin, 51.9974 wt.% aloe veragel, 30 wt.% honey, 10 wt.% rose water, 3 wt.% grapeseed oil and 5 wt.% rice flower. A second control cosmetic composition sample was prepared wherein the control cosmetic composition comprises 0.15 wt.% quercetin, 0.15 wt.% curcumin, 51.7 wt.% aloe vera gel, 30 wt.% honey, 10 wt.% rose water, 3 wt.% grapeseed oil and 5 wt.% rice flower. The amount of quercetin and curcumin is outside of the range of the invention in both the first control cosmetic composition and the second cosmetic control composition. The control cosmetic composition samples were tested according to the same test method as the inventive cosmetic composition for 2 weeks. The results for the first control sample after 1- and 2-weeks of administration are shown in figure 5 and figure 6 respectively. The results for the second control sample 2-weeks of administration are shown in figure 7.

[0137] The average percentage change in L’Oreal Skin Genius® scores across the attributes of skin aging measured between day 0 and day 15 as it pertains to the first control cosmetic composition comprising 0.0013 wt.% quercetin and 0.0013 wt.% curcumin are shown in table 2.

[0138] Table 2 *p<0.05, ns = not significant

[0139] The average percentage change in L’Oreal Skin Genius® scores across the attributes of skin aging measured between day 0 and day 15 as it pertains to the second control cosmetic composition comprising 0.15 wt.% quercetin and 0.15 wt.% curcumin are shown in table 3.

[0140] Table 3

[0141] *p<0.05, **p<0.01, ns = not significant

[0142] ^reported as median percentage change owing to outliers The results indicated no demonstrable significant effect of the cosmetic composition comprising 0.0013 wt.% quercetin and 0.0013 wt.% curcumin on any skin attribute measured after both 1 week and 2 weeks of administration. In particular, the results show that the appearance of wrinkles, deep wrinkles, radiance and firmness of the skin were worse after 2 weeks of administration. This confirms that the cosmetic composition comprising 0.0013 wt.% quercetin and 0.0013 wt.% curcumin is not effective in improving skin aging attributes after 2 weeks of administration. The results also indicated that the cosmetic composition comprising 0.15 wt.% quercetin and 0.15 wt.% curcumin was not effective in improving any skin aging metrics after 2 weeks of administration. In particular, the results show that the appearance of wrinkles, deep wrinkles, fine lines, radiance, pigmentation and firmness were worse after 2 weeks of administration. This confirms that the cosmetic composition comprising 0.15 wt.% quercetin and 0.15 wt.% curcumin is not effective in improving skin aging attributes after 2 weeks of administration.

[0143] The above embodiment is described by way of example only. Many variations are possible without departing from the scope of the invention as defined in the appended claims.
