Does GHK-Cu actually work for skin?

There is a real research basis for its role in collagen synthesis and skin remodeling, which is why it is a long established cosmetic ingredient rather than a fringe one. This site's citation review found no injectable human clinical trial for GHK-Cu specifically; its evidence base leans on topical and cell level research. It is approved for cosmetic use, not as a medical drug, in every country this site tracks.
