Polyvinyl alcohol and collagen peptide: keep them apart

Keep them apart

Use them at different times of day, with the peptide product first, because the alcohol in the other item can break down the peptide. The strong alcohol ruins the firming protein, making the skincare product less effective. The shopper can switch to a gentler product or wait longer between applications.
