GHK-Cu is a naturally occurring copper-binding peptide made up of three amino acids—glycine, histidine, and lysine—combined with a copper ion. It was first identified in human plasma, with levels that tend to decline as people age. GHK-Cu plays an important role in the body’s natural repair processes, particularly in wound healing and tissue regeneration. It helps activate genes involved in cell growth, collagen production, and the formation of new blood vessels, all of which contribute to healthier, more resilient skin.
Because of these properties, GHK-Cu has become widely used in skincare and cosmetic formulations. It is known to improve skin firmness and elasticity, reduce the appearance of fine lines and wrinkles, and enhance overall skin texture. Its anti-inflammatory and antioxidant effects also help calm irritated skin and protect against environmental damage. In addition to skin benefits, some studies suggest that GHK-Cu may promote hair growth by stimulating hair follicles and improving scalp health.
Beyond cosmetic uses, researchers are exploring its potential in broader medical applications, including nerve regeneration, tissue repair, and anti-cancer activity.
