Copper peptide and isopropyl alcohol: keep them apart

Keep them apart

Use them at different times of day, applying the alcohol first and the peptide later, because the alcohol ruins the peptide. The strong alcohol breaks down the delicate copper peptide before it can help firm and smooth the skin. The shopper can switch to a gentler alcohol-free toner or wait an hour between products.
