GHK-Cu is a copper-binding peptide researched for skin remodeling and repair. Cell studies examine connective-tissue production, a small human facial-serum study measured wrinkles, and clinics such as Perfect B discuss skin and hair goals with injectable use.

Evidence in this guide: Human topical research, laboratory findings and clinic-reported injectable practices are different evidence streams.
