GHK-Cu is a naturally occurring copper-peptide complex that declines with age. Applied topically, it is believed to stimulate collagen and elastin production, improve tissue repair, and exert anti-inflammatory and antioxidant effects. These actions can improve skin elasticity and firmness and reduce the appearance of fine lines, contributing to the healthspan of the skin as an organ.
