Arginine and copper peptide: work well together

Work well together

Use them together in the same routine, applying the amino acid first and the peptide second for better moisture and firmness. Arginine helps feed the skin so the copper peptide can better support firm, healthy-looking skin. You can continue using both together, but if your skin feels sensitive, try using a gentler formula or waiting a few minutes between steps.
