PALMITOYL PENTAPEPTIDE-4
Palmitoyl-Pentapeptide-4 is a peptide obtained as a reaction product of palmitic acid and pentapeptide-4. It is also called Matrixyl and consists of a short peptide chain with five amino acids (lysine, threonine, threonine, lysine, serine) bound to palmitic acid.
Palmitoyl-pentapeptide-4 is a biologically active peptide that is reported to stimulate the production of elastin, fibronectin, glycosaminoglycan, and collagens (particularly types I, III, and IV) as well as aid in wound healing.1Studies have shown it to be effective in reducing periorbital wrinkles by decreasing wrinkle depth and increasing skin barrier function and skin elasticity.
