What is Copper-GHK?

Copper-GHK, also referred to as GHK-Cu, is a complex formed by the tripeptide glycyl-L-histidyl-L-lysine (GHK) and copper ions. This structure is essential for its function, as it allows the peptide to deliver copper in a bioavailable and non-toxic form to cells. First isolated in 1973, the GHK tripeptide is renowned for its strong affinity for copper ions, especially Cu(II), forming a stable chelate complex (PMC). Detailed studies using X-ray crystallography and NMR spectroscopy have shown that the copper ion is coordinated by the nitrogen atoms from the imidazole side chain of histidine, the alpha-amino group of glycine, and the deprotonated amide nitrogen of the glycine-histidine peptide bond (PMC). This configuration not only stabilises the copper ion but also neutralises its redox activity, preventing oxidative damage while facilitating essential cellular processes. GHK’s ability to bind copper is crucial, as copper acts as a cofactor for numerous enzymes involved in collagen synthesis, antioxidant defence, and cellular respiration, making GHK-Cu a potent agent in skin health and regeneration (SpringerLink). Additionally, GHK-Cu can form binary and ternary complexes, potentially involving albumin, which enhances its stability and functionality in physiological conditions (PMC).

Copper-GHK plays a critical role in skin health by modulating cellular pathways essential for regeneration and repair. It enhances collagen production, vital for maintaining skin elasticity and firmness, with studies showing increased collagen synthesis in 70% of women treated with GHK-Cu compared to 50% with vitamin C cream (PMC). Furthermore, GHK-Cu stimulates dermal keratinocyte proliferation, crucial for skin density and thickness, reducing fine lines and wrinkles (PMC). Its ability to penetrate the skin’s stratum corneum allows it to activate regenerative processes effectively, making it a potent agent in anti-ageing skincare (PMC). Additionally, GHK-Cu exhibits anti-inflammatory properties by reducing pro-inflammatory cytokines like IL-6, which can impede skin healing and lead to scarring (PMC). This anti-inflammatory action positions copper-GHK as a potential alternative to corticosteroids in treating inflammatory skin conditions. Moreover, its role in DNA repair, particularly in restoring irradiated fibroblast function, underscores its importance in skin health, promoting growth factor production necessary for wound healing and tissue renewal (PMC). Overall, copper-GHK’s biological functions in skin health are multifaceted, encompassing collagen stimulation, keratinocyte proliferation, anti-inflammatory effects, and DNA repair, making it a promising candidate in anti-ageing treatments.
