Benzoyl peroxide and mandelic acid: keep them apart

Keep them apart

Use them on alternate nights because combining them causes over-exfoliation and irritation. Benzoyl peroxide fights acne while mandelic acid exfoliates, but using them together damages your skin barrier. You can switch to a gentler strength or space out the applications to prevent redness.
