Hexapeptide-9 and isopropyl alcohol: keep them apart

Keep them apart

Use them at different times of day, applying the peptide first and the alcohol later, because the alcohol ruins the peptide. The strong alcohol breaks down the firming peptide before it can smooth wrinkles on your skin. You can switch to a gentler product or wait longer between applying them.
