GHK-Cu (Copper Peptide) is a naturally occurring tripeptide (Gly-His-Lys) that binds to copper ions, forming a complex involved in wound healing, skin regeneration, and tissue repair. Discovered in human plasma, it plays a key role in activating genes related to collagen production, anti-inflammation, and antioxidant defense.
GHK-Cu is widely used in cosmetic and anti-aging products for improving skin elasticity, reducing wrinkles, and promoting hair growth. It is also being studied for broader therapeutic applications, though it is not FDA-approved for medical treatment.
