Cosmetic compositions and methods for using same to improve the aesthetic appearance of skin
View Patent ↗The present invention relates to compositions useful in treating the various signs of dermatological aging in human skin. The present invention also relates to cosmetic compositions and methods of using such compositions that improve the aesthetic appearance of skin. Further, the present invention relates to methods of applying the compositions to the skin to effect treatment and to improve the aesthetic appearance of skin, particularly, by providing anti-aging benefits to the skin. Suitable anti-aging agents include 3,3′-thiodipropionic acid and/or its derivatives.
1. A method for improving the aesthetic appearance of skin comprising topically applying to wrinkled skin a cosmetic composition comprising (i) from about 0.0001 to about 30% by weight of the total composition of a compound according to Formula (I):
and (ii) a cosmetically acceptable vehicle in the form of an emulsion comprising water and an emulsifier,
wherein R 1 and R 2 are independently selected from the group of substituents consisting of hydrogen; alkyls, substituted or unsubstituted, branched or linear; alkenyls, substituted or unsubstituted, branched or linear, and having up to 5 double bonds; alkynyls, substituted or unsubstituted, branched or linear and having up to 5 triple bonds; aryls, substituted or unsubstituted; cycloalkyls, substituted and unsubstituted; and cycloalkenyls, substituted and unsubstituted, and
wherein the compound according to Formula I is present in said cosmetic composition in an amount effective to reverse the loss of collagen and/or elastin and to reduce the appearance and/or depth of wrinkles on the wrinkled skin; and with the proviso that said composition does not comprise methylthioadenosine.
2. The method of claim 1 , wherein the compound of Formula (I) is 3,3′-thiodipropionic acid.
3. The method of claim 1 , wherein the compound of Formula (I) is present in an amount of from about 0.001 to about 10% by weight of the composition.
4. The method of claim 3 , further comprising an ingredient selected from the group consisting of retinoid, salicylic acid, an oxa acid, oxa diacid, an alpha hydroxy acid, a beta hydroxy acid, and any combination thereof.
5. The method of claim 2 , wherein 3,3′-thiodipropionic acid is present in the composition in an amount of from about 0.001 to about 10% by weight of the composition.
6. The method of claim 4 , further comprising an ingredient selected from the group consisting of lactic acid, glycolic acid, 3,6,9-trioxaundecanoic acid, and any combination thereof.
