Anti wrinkle Palmitoyl Pentapeptide-4 / Matrixyl Acetate CAS 214047-00-4

Palmitoyl pentapeptide-4 (Pal-Lys-Thr-Thr-Lys-Ser = Pal-KTTKS) contains 5 amino acids linked to a 16-carbon aliphatic chain for improving the penetration of the molecule through the lipid structures of the skin. It is a matricide.[citation needed] Matrikines are messenger peptides capable of regulating cell activities by interacting with their specific receptors. They activate certain genes involved in the process of extracellular matrix renewal and cell proliferation.By activating the neosynthesis of extracellular matrix macromolecules, palmitoyl pentapeptide-4 provides an anti-wrinkle effect.[medical citation needed] Studies (in vitro and in vivo) demonstrating the anti-wrinkle efficacy of this peptide have been conducted and published by Sederma and by independent organisations.
