GHK-Cu (Glycyl-L-Histidyl-L-Lysine-Copper) is a naturally occurring copper-binding peptide found in human plasma, saliva, and tissues. Composed of a tripeptide bound to a copper ion, GHK-Cu has been widely studied for its involvement in tissue repair, cellular signaling, and protective biological responses. Research indicates that GHK-Cu plays a role in wound-healing pathways, modulating inflammation, and supporting structural components of the skin.
Scientific interest in GHK-Cu has grown due to its potential influence on gene expression related to regeneration, antioxidant activity, and extracellular matrix organization. These properties have made it a prominent subject in dermatologic, cosmetic, and regenerative research.
Investigational studies have examined GHK-Cu’s potential roles in collagen production, skin renewal, hair-follicle activity, and barrier support, as well as its ability to bind and transport copper—an essential trace mineral involved in enzymatic and cellular processes.
GHK-Cu remains a highly researched peptide for its multifunctional activity and its relevance across skin health, tissue-repair mechanisms, and molecular signaling pathways.
