Copper Tripeptide-1
The peptide science trusts for skin renewal.
Copper Tripeptide-1 (GHK-Cu) is a naturally occurring peptide found in human plasma that plays a crucial role in tissue repair and regeneration. As we age, our natural GHK-Cu levels decline, contributing to slower healing and visible signs of aging.
In skincare, topically applied copper peptides have been shown to stimulate collagen synthesis, promote wound healing, and reduce the appearance of fine lines — making them one of the most evidence-backed anti-aging ingredients available.
Key Benefits
Collagen Stimulation
Signals skin cells to produce more collagen and elastin, the structural proteins responsible for firm, youthful-looking skin.
Accelerated Repair
Speeds up the skin’s natural repair process, making it ideal for post-procedure recovery and treating minor damage.
Anti-Wrinkle
Reduces the depth and appearance of fine lines and wrinkles through enhanced collagen and glycosaminoglycan production.
Antioxidant Defense
Copper ions support the skin’s antioxidant enzyme systems, providing an additional layer of protection against environmental damage.
The Science
Research published in the Journal of Cosmetic Dermatology demonstrated that GHK-Cu increased collagen synthesis by up to 70% in treated skin samples compared to controls.
Clinical studies have shown that copper peptides can improve skin thickness, elasticity, and firmness within 12 weeks of consistent topical application, with results comparable to retinol but without the irritation.
