Instead, Robinson and Chan advocate relegating benzoyl peroxide to your morning routine and retinol to your nighttime one. Neutrogena’s Stubborn Acne + Marks line makes this straightforward to recollect. 

Benzoyl peroxide (or BPO, as Robinson calls it) pairs effectively with a prescription-grade ingredient referred to as topical clindamycin, which “works synergistically with BPO to combat acne-causing bacteria,” Robinson says. Retinol, then again, is healthier suited with hydrating glycerin, hyaluronic acid, and niacinamide-based formulation, she provides. 

5. Retinol & AHAs

Another recipe for main irritation is retinol blended with alpha hydroxy acids, like glycolic, lactic, and citric. “Both of these ingredients disrupt the skin barrier,” Chan explains. If you double crew your complexion with them, extreme dryness, redness, sensitivity, or a rash are very doable outcomes. 

Instead, alternate the times you throw them on. One or two occasions every week, Chan reaches for an AHA with a ten to twenty % focus. On the opposite days — and if her pores and skin is not performing up —  retinol is put into motion.
