Run a 4-step routine for 12 weeks. Gentle cleanser twice a day. Spot-treat active whiteheads with a hydrocolloid patch — a Rael Miracle Patch, Hero Mighty Patch, or COSRX. Apply 2% salicylic acid leave-on at night (Paula's Choice BHA or COSRX BHA). Oil-free moisturizer (CeraVe, La Roche-Posay Toleriane). SPF 30+ every morning. Add adapalene 0.1% gel (Differin, OTC since 2016) at night for stubborn comedonal acne. Skip the squeeze. It scars and prolongs the cycle. Wash pillowcases weekly. If skin is still inflamed after 12 weeks, book a dermatologist for prescription tretinoin or spironolactone.
