Tetrapeptide-21 is a type of synthetic peptide compound which combines several chains of amino acids, which lead to an increased elasticity and a decreased volume of wrinkles and fine lines. Formulations containing 5% Tetrapeptide-21 have shown a 25% improvement in skin roughness and depth of fine and coarse wrinkles. Synthetic Tetrapeptide-21 have shown promise as a skin cream ingredient that can stimulate skin growth and repair. When collagen breaks down, it forms specific Tetrapeptides that signal to your skin that it was damaged and needs to make new collagen.
Tetrapeptide-21 is a cell communicating peptide that prevents damage caused by UV radiation. Moreover, it promotes DNA repair, to provide a complete protection system against intrinsic and extrinsic aging.
