Copper is a trace element and it’s present in every cell in your body. Peptides are small protein fragments, and when combined with copper they form copper peptides which can be used in skin care products to help with wound healing. Because the peptide formulation enables the copper to penetrate the skin, copper peptides are used to treat wrinkles and fine lines, acne scars and stretch marks. Copper peptides also stimulate the production of collagen and appear to enhance antioxidant activity. Copper peptides are available in a range of skin care formulations such as lotions, body creams, face creams and serums.
