Palmitoyl Tripeptide-8 is a signal peptide that can promote the synthesis of collagen (types I, II, and IV) and extracellular matrix proteins by increasing fibroblast activity, making the skin appear younger and more elastic. When added to cosmetics, it helps replenish collagen in the skin, enhances facial elasticity, and significantly reduces facial wrinkles. Additionally, it has properties that enhance cellular activity, increase skin hydration, boost skin radiance, and improve skin tone.
