Copper Tripeptide-1 (also known as GHK-Cu) is a bioactive copper peptide complex composed of the tripeptide glycyl-L-histidyl-L-lysine (GHK) bound to a copper ion (Cu²⁺). It is widely used in cosmetic and dermatological formulations for its powerful skin-repairing, anti-aging, and wound-healing properties.
This peptide naturally occurs in the human body and plays an important role in tissue regeneration and skin remodeling. When used in skincare, Copper Tripeptide-1 helps stimulate collagen and elastin production, improve skin firmness, and promote faster repair of damaged skin.
Because of its regenerative and antioxidant properties, it is commonly included in premium anti-aging products, hair growth treatments, and skin repair formulations.
