Skin aging is partly structural (collagen loss) and partly damage (oxidative stress). The GHK-Cu + glutathione blend addresses both — GHK-Cu stimulates remodeling while glutathione neutralizes oxidative damage.

It's a logical topical combination, though members note that copper and antioxidants can sometimes interact chemically, which complicates formulation. Discussed as a conceptually sound but formulation-sensitive pairing.
