GHK‑Cu
(Glycyl‑L‑Histidyl‑L‑Lysine + Copper) is a natural tripeptide–copper complex found in human plasma, with levels that decline with age.
It has demonstrated powerful regenerative effects in both dermal and systemic tissues: stimulating the production of collagen, elastin, and proteoglycans; promoting keratinocyte and fibroblast migration; and modulating genes related to inflammation, oxidation, and wound healing.
It is regarded as a potent anti-aging agent for both skin and systemic health.
