Copper Tripeptide-1
What is Copper Tripeptide-1?
Copper Tripeptide-1, chemically known as copper glycyl-L-histidyl-L-lysine, is a synthetic tripeptide bound to a copper(II) ion. It replicates a natural peptide found in human plasma, produced via solid-phase synthesis. Primarily categorized as a skin conditioning agent in cosmetics, it appears in anti-aging serums, creams, eye treatments, and hair care formulations. In products, it works by binding to copper ions, which facilitates cellular signaling pathways. This interaction influences fibroblast activity, encouraging production of extracellular matrix components like collagen and glycosaminoglycans. It also demonstrates copper-dependent antioxidant effects, scavenging reactive oxygen species, and modulates copper-zinc balance in skin tissues. The ingredient imparts a characteristic blue hue to formulations at effective levels, aiding product stability and penetration.
