Benzoyl peroxide and sodium lauryl sulfate: keep them apart

Keep them apart

Use them at different times of day, applying the cleanser first and the benzoyl peroxide later, because combining them causes severe skin dryness. Sodium lauryl sulfate strips the skin barrier while benzoyl peroxide dries it out, making the irritation much worse together. The shopper can switch to a gentler cleanser or use the products on alternate nights.
