Keep them apart

Use them at different times of day, applying the cleanser first and the [benzoyl peroxide](https://lovi.care/skincare/ie/ingredients/benzoyl-peroxide) later, because combining them causes severe skin dryness. [Sodium lauryl sulfate](https://lovi.care/skincare/ie/ingredients/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.
