GHK-Cu is a naturally occurring copper-bound tripeptide (glycyl-L-histidyl-L-lysine) that promotes skin repair, wound healing, and tissue regeneration.

What GHK-Cu Is
GHK-Cu is a small peptide-metal complex consisting of the tripeptide glycine-histidine-lysine (GHK) bound to a copper ion (Cu²⁺) and is also known as Copper Tripeptide-1 in cosmetic ingredient lists. It occurs naturally in human plasma, saliva, urine, and wound fluid, with levels peaking in young adulthood (~200 ng/mL) and declining with age (~80 ng/mL by age 60),. The copper component is essential for its biological activity, as it supports collagen crosslinking, antioxidant enzyme function, and connective tissue formation.

Biological Functions
GHK-Cu acts as a signaling molecule that regulates tissue remodeling and repair. Its key functions include:
Stimulating collagen and elastin production, improving skin firmness and reducing fine lines.

Promoting wound healing and tissue regeneration by attracting immune cells and enhancing angiogenesis.

Exhibiting anti-inflammatory and antioxidant effects, reducing cytokines like IL-6 and modulating oxidative stress.

Supporting hair growth by enlarging hair follicles and extending the growth phase.

At the molecular level, GHK-Cu can modulate the expression of thousands of human genes, including those involved in DNA repair, mitochondrial function, and suppression of pathways associated with aging and cancer.

Applications
GHK-Cu is widely used in cosmetic and therapeutic contexts:
Topical formulations (serums, creams) target skin repair, anti-aging, and hair growth.

Injectable forms are used experimentally for systemic anti-aging, wound healing, and tissue regeneration, though long-term safety data for systemic use is limited.

Cosmetic concentrations are typically very low (up to 0.002%) and have decades of safety data.
