Copper and collagen peptide: keep them apart

Keep them apart

Use them on alternate nights, applying copper peptides on one evening and vitamin C or niacinamide on the next. Mixing these ingredients can cause them to oxidize and cancel out their skin benefits. You can easily fix this by using them on different days or waiting a few minutes between layers.
