Zinc sulfate and copper peptide: keep them apart

Keep them apart

Apply them at different times of day, using copper peptide in the morning and zinc sulfate at night, because mixing them makes the peptide inactive. Unchelated metal ions like zinc can bind to peptides and stop them from working properly on your skin. To fix this, simply use them in separate routines or look for a product that already includes chelating agents for stabilization.
