Polyvinyl alcohol and peptide-rich plasma
Keep them apart
Use them at different times of day, applying the peptide product first and the alcohol product later, because they clash in the same routine. The strong alcohol can break down the delicate peptide structure, stopping it from working properly on your skin. To fix this, you can space them out into separate morning and night routines.
