Run a three-step nightly routine: gentle fragrance-free cleanser (CeraVe Foaming or La Roche-Posay Effaclar), adapalene 0.1% (Differin Gel, $13 at CVS), and a non-comedogenic moisturizer. In the morning, swap adapalene for 2.5 to 5% benzoyl peroxide cleanser and SPF 30+. The AAD says full clearing takes 8 to 12 weeks of consistent use — stop swapping products. Change your pillowcase twice a week; sleep transfers sebum and bacteria back to your face. Keep hands off your face during the day. Stash Hero Mighty Patch or Starface for active whiteheads. If breakouts continue past 12 weeks, see a dermatologist — recurring acne past adolescence may be hormonal.
