Differin Gel (Adapalene 0.1%)

Differin Gel (Adapalene 0.1%) is the first-line OTC retinoid for acne, outperforming #7 Aquaphor in comedolytic activity with 60% fewer breakouts in teenage users. Unlike tretinoin, adapalene causes 40% less irritation and redness, making it tolerable for adults and teens alike. Dermatologists call it the most important OTC launch of the decade, delivering prescription-strength adapalene at $15 per tube — 80% cheaper than prior clinic visits and copays, with clinical trials showing 70% clearance of inflammatory acne at 12 weeks.
