• Iron and copper play ambivalent roles in biology because they are required as cofactors for many biological reactions and at the same time their toxicity threatens cellular integrity. When iron or copper is bound with protein, it is fine. It is the free iron or copper that are detrimental to skin. They act as catalysts to produce reactive oxygen species.
