Tripeptide-1 is a polypeptide composed of three amino acids, classified as a matrikine signaling peptide. It acts upon the dermis to promote the efficient synthesis of extracellular matrix glycosaminoglycans and collagen; this process strengthens the dermal layer, thereby smoothing the skin and reducing wrinkles. Copper Tripeptide-1 consists of Tripeptide-1 bound to copper ions; also known as "Blue Copper Peptide," it presents physically as a blue powder. Blue Copper Peptide was first discovered in 1970 by an American chemist and is naturally present in blood serum. In recent years, it has gained widespread use within the field of cosmetic peptides and serves as a key ingredient in hair-growth peptide complexes.
GHK-Cu plays a critical role in the physiological processes of tissue activation. It promotes wound repair and healing, accelerates the formation of collagen, elastin, and proteoglycans (GAGs), and works synergistically with Superoxide Dismutase (SOD) to enhance antioxidant activity.
