Copper gluconate, the copper salt of gluconic acid, is an ingredient that delivers the important trace element copper to the skin. Copper is vital for the appropriate functioning of almost all tissues in the human body.1 In the skin, copper is involved in collagen synthesis, wound healing, and skin regeneration.1 A cofactor of superoxide dismutase, copper functions as a powerful antioxidant that can help inhibit damage from pollution and other environmental stressors.1
