Abstract

Collagen is the most abundant animal protein in mammals, accounting for about 30 % of all proteins. It is present in connective tissue and contributes to the structural framework of most organs. The tripeptide (glycineproline-hydroxyproline) with the INCI name Tripeptide-29 is main component of collagen type I. The palmitoyl tripeptide (palmitoyl-glycine-proline-hydroxyproline) with the INCI name Paimitoyi Tripeptide-29 is a synthetic material that was designed as a topical agent to stimulate collagen production. We synthesized the palmitoyl tripeptide as a potential anti-wrinkle compound. This compound has been characterized using HPLC. This compound proved, through in vitro tests, to stimulate collagen production and fibroblast proliferation. These results were very promising, so human studies were subsequently performed. We investigated the skin improvement effect of the palrnitoyl tripeptide on human skin by using non-invasive instruments. We measured physiological effects such as skin wrinkles and elasticity after volunteers applied the cosmetic products for 8 weeks. We observed significant improvement in skin wrinkles and elasticity after use of the cosmetic products for 8 weeks. We concluded that the palmitoyl tripeptide had an anti-aging effect on human facial skin.
