copperpeptide

Copper peptides are a group of three amino acids linked to copper ions. They occur naturally in human plasma, saliva, and urine. In skincare, copper peptides are often synthesized and incorporated into topical products. Their primary proposed functions include stimulating collagen and elastin production, which are vital proteins for skin structure and elasticity. They are also thought to possess antioxidant and anti-inflammatory properties, potentially aiding in wound healing and reducing the appearance of wrinkles and fine lines.

The most commonly studied and utilized copper peptide in cosmetics is GHK-Cu, which stands for Glycyl-L-Histidyl-L-Lysine coupled with a copper (II) ion. Research suggests that GHK-Cu can promote the synthesis of glycosaminoglycans, such as hyaluronic acid, further contributing to skin hydration and firmness. Additionally, it is believed to help remove damaged collagen and elastin from the skin, making way for new tissue.

Copper peptides are generally considered safe for most skin types when used in appropriate concentrations within cosmetic formulations. They are often found in serums, moisturizers, and anti-aging treatments. However, as with any skincare ingredient, individual sensitivities can occur. It is advisable to patch-test new products and consult with a dermatologist if you have specific concerns or pre-existing skin conditions. Their use is also being explored in other areas beyond skincare, including wound healing and hair growth.
