What Is Copper Peptide?
Copper peptides are small protein fragments bound to copper ions. The most well-known form, GHK-Cu (Copper Tripeptide-1), naturally occurs in human plasma and decreases with age. This peptide plays a crucial role in wound healing and tissue regeneration.
Research has shown that copper peptides stimulate collagen and elastin production, support the skins natural healing processes, and provide antioxidant protection. They also help regulate copper-dependent enzymes essential for skin health.
In skincare, copper peptides are prized for their ability to support skin remodelling and improve the appearance of ageing skin. They work well alongside other anti-ageing ingredients to promote firmer, more resilient skin.
