Palmitoyl Tetrapeptide-20

Palmitoyl Tetrapeptide-20

Overview
Palmitoyl Tetrapeptide-20 is a synthetic signal peptide widely used in high-end skincare products. It is composed of a sequence of four amino acids (Lysine-Threonine-Threonine-Lysine) linked to a palmitoyl group (a fatty acid). This structure allows it to mimic key signals in the skin's natural repair processes. Its primary function is to stimulate the synthesis of glycosaminoglycans (such as hyaluronic acid), leading to deep hydration, improved skin elasticity, and reduction in the appearance of wrinkles.
