Usage, safety and formulation details
Mechanism of action
Copper binding and cell-signaling effects have been investigated; laboratory wound-related findings do not establish a clinical wound treatment.
Sources: 1, 2Potential adverse effects
Irritation or contact allergy may occur; stop a product that causes a persistent or marked reaction.
Sources: 1, 2Formulation considerations
Peptide stability, copper speciation, pH and delivery matter. Do not infer blanket incompatibility with every acid or antioxidant.
