GHK-CU in this respect is a strong protector of tissue and an anti-inflammatory agent that prevent the oxidative tissue damage that is most commonly associated with improper healing after injuries. In addition, it results to cell signaling that is responsible for tissue remodeling which involves removal of damaged/scarred tissue and the creation of new, healthy tissue. Nevertheless, these positive effects vanish with time as body concentration of GHK-Cu which is associated with aging are diminished. With aging, the number decreases of stem cells that bring inflammation, cancers, and destruction of aged tissues growth. Because of its significance in the system of the skin, GHK-Cu is a commonly found ingredient in cosmetics products, as well as in-hair regrowth.
