Matrixyl 200mg (Palmitoyl Pentapeptide-4) is one of the best-known cosmetic peptides, supplied by Peptide Sciences as a topical-grade powder for formulation research.
Matrixyl Research Overview
Matrixyl is the palmitoylated form of KTTKS, a fragment of type I procollagen. Research suggests such matrix fragments signal fibroblasts to produce more collagen, fibronectin and glycosaminoglycans. It was one of the first “matrikine” peptides widely studied in skin-ageing formulations.
