Acetyl hexapeptide-3 and mandelic acid: keep them apart

Keep them apart

Use them at different times of day by applying your acid first and your peptide later, because acids break down peptides. Acidic products clash with peptides and can make them less effective on your skin. You can switch to a milder acid or wait longer between steps.
