Palmitoyl Tetrapeptide-3

Palmitoyl Tetrapeptide-3

Overview
Palmitoyl Tetrapeptide-3 is a synthetic signal peptide widely used in cosmetics and skincare products. It is composed of a sequence of four amino acids (Glycine-Glutamine-Proline-Arginine) linked to a palmitic acid group. This structure allows it to mimic fragments of proteins naturally found in the skin (such as fragments of collagen), thereby signaling skin cells to promote the synthesis of collagen and glycosaminoglycans (like hyaluronic acid).
