Copper peptide also known as GHK-Cu is a well-studied peptide, due to its ability to reduce visible signs of aging. Copper peptides are found naturally within the body where they play a role in many important processes within the skin. Copper Peptides have been researched for their role in reducing the appearance of fine lines and wrinkles, whilst improving skin elasticity and firmness due to their role in helping support collagen production. As one ages, the natural levels of this peptide diminish, potentially contributing to visible signs of aging.
