The formula incorporates five well-studied peptide technologies, skin-friendly amino acids, and multiple hyaluronic acids. For those looking for a multi-functional solution for skin care, Multi-Peptide + Copper Peptides 1% helps to improve the appearance of fine lines and supports your skin’s overall elasticity, smoothness and firmness.
