Description

Pal-KTTKS is a lipidated pentapeptide consisting of a fragment of the type I collagen C-terminal propeptide conjugated to palmitic acid .1 It increases collagen production in human corneal and dermal fibroblasts when used at concentrations of 0.002, 0.004, and 0.008 wt%.2 Following topical administration, pal-KTTKS (50 μg/cm2) is found in the stratum corneum, epidermis, and dermis of isolated hairless mouse skin.1 It can self-assemble into flat tapes and extended fibrillar structures.3 Pal-KTTKS has been detected in anti-wrinkle creams.4
