Will GHK-Cu help with loose skin?

It is researched for collagen synthesis and skin remodeling, which is mechanistically related to skin firmness, and it is a long established, approved cosmetic ingredient on that basis. This site's review found no injectable or topical human clinical trial specifically measuring loose skin or skin laxity as an outcome, so this is a plausible extension of its established research rather than a directly measured result.
