Polyvinyl alcohol and palmitoyl pentapeptide-4: keep them apart

Keep them apart

Apply them at different times of day, using the peptide first and the alcohol product later, because they clash and cancel each other out. The strong alcohol breaks down the delicate peptide structure, so your skin misses out on the firming benefits. You can safely use them by separating your routine or switching to a gentler alcohol-free formula.
