Description:

Palmitoyl pentapeptide-4 is at least as effective against wrinkles as retinol but does not cause skin irritation, which is a common side-effect of retinoids.

Chemically speaking, palmitoyl pentapeptide-4 (Pal-KTTKS) is a relatively small molecule. It consists of five amino acids linked together and attached to a fatty acid to enhance oil solubility for the sake of better skin penetration. It is structurally related to the precursor of collagen type I (a.k.a. procollagen type I). When added to the culture of fibroblasts (the key skin cells), palmitoyl pentapeptide-4 stimulated the synthesis of the key constituents of the skin matrix: collagen, elastin and glucosamnoglycans.
