Benzoyl peroxide and copper peptide: keep them apart

Keep them apart

Use them at different times of day, applying benzoyl peroxide in the morning and copper peptides at night, because they cancel each other out. Benzoyl peroxide oxidizes copper peptides and makes them useless on your skin. You can easily fix this by separating them into different routines or using them on alternate days.
