Pentapeptide-3

Synonyms: Lysyl-threonyl-threonyl-lysyl-serine, KTTKS, Pentapeptide-3 (INCI)

Pentapeptide-3 is a synthetic pentapeptide with the sequence lysyl-threonyl-threonyl-lysyl-serine (KTTKS), corresponding to the carboxyl-terminal fragment of type I collagen. It is manufactured via solid-phase peptide synthesis and supplied as a high-purity powder (≥98% by HPLC).

As a cosmetic ingredient, Pentapeptide-3 is valued for its ability to stimulate collagen production and improve skin firmness. It is incorporated into anti-aging formulations, often in conjunction with other actives to enhance efficacy. The peptide is also used as a research tool in collagen-related studies.
