GHK-Cu

GHK-Cu (glycyl-L-histidyl-L-lysine–copper complex) is a naturally occurring peptide that promotes tissue regeneration, skin rejuvenation, and wound healing by stimulating collagen and elastin production.

Its benefits are supported by scientific research showing it modulates gene expression to reduce inflammation, protect against oxidative stress, and accelerate cellular repair processes.

Key Benefits

• Skin Rejuvenation: It improves skin firmness, elasticity, and texture by boosting collagen synthesis (up to 70% in some studies) and reducing wrinkle depth. It also helps even out skin tone and repair the skin barrier.
• Wound Healing: GHK-Cu accelerates wound closure (by 30–50% in some studies), enhances vascularization, and reduces scar formation by modulating inflammatory responses and promoting tissue remodeling.
• Hair Growth: It supports hair follicle health by stimulating blood vessel growth, reducing scalp inflammation, and prolonging the anagen (growth) phase, which may increase hair density and thickness.
• Anti-Aging & Cellular Protection: As a powerful antioxidant, it reduces reactive oxygen species and suppresses pro-inflammatory cytokines. It also helps reset gene expression in aged cells to more youthful patterns.

Usage and Considerations

GHK-Cu is available in topical serums/creams (0.1%–2% concentration) and injectable forms (mesotherapy or IV), though human clinical data for systemic use is still emerging. While generally well-tolerated, potential side effects include mild skin irritation, redness, or breakouts in acne-prone individuals. It is contraindicated for people with copper metabolism disorders like Wilson’s disease or hemochromatosis.
