Elastin protective polyphenolics and methods of using the same
View Patent ↗Dermal fibroblasts permanently loose their ability to synthesize elastin, the major component of elastic fibers, shortly after puberty. This progressive loss of elastic fibers cannot be replaced, resulting in the physical signs of aging. The present invention provides methods and compositions containing the polyphenols ellagic acid and/or tannic acid for protection against degradation of cutaneous elastic fibers by the elastolytic enzymes. The use of ellagic acid and/or tannic acid increased the overall deposition of elastic fibers in healthy and damaged skin cells. The protection of both intra-tropoelastin and extra-cellular mature elastic fibers from proteolytic enzymes by ellagic acid and tannic acid caused an increase in the net deposition of elastic fibers. Therefore, embodiments of the present invention provide methods and composition for the treatment of skin and prevention and treatment of degradation of dermal elastic fibers.
1. A method for reducing photo-induced damage to the skin comprising administering to the skin in need thereof a composition comprising about 1 microgram to about 10 micrograms of a polyphenolic compound and a peptide having a sequence Val-Gly-Val-Ala-Pro-Gly (SEQ ID NO: 19), wherein the photo-induced damage to the skin is reduced.
2. The method of claim 1 , wherein said polyphenolic compound is selected from tannic acid, ellagic acid and combinations thereof.
3. The method of claim 1 , wherein the amount of said polyphenolic compound in the composition is about 1 μg.
4. A method of treating damage to the skin of a subject comprising topically administering to the skin in need thereof a composition comprising about 1 microgram to about 10 micrograms of a polyphenolic compound and a peptide having a sequence Val-Gly-Val-Ala-Pro-Gly (SEQ ID NO: 19), wherein the deposition of insoluble elastin fibers is increased.
5. The method of claim 4 , wherein said polyphenolic compound is selected from tannic acid, ellagic acid and combinations thereof.
6. The method of claim 4 , wherein the amount of said polyphenolic compound in the composition is about 1 μg.
