The $13 OTC Adapalene That Packs Prescription-Strength Retinoid Power
Dermatologists note that adapalene, a potent retinoid once available only by prescription, is now sold OTC in products like Differin, offering acne-fighting and texture-boosting benefits with potential for dryness. Several affordable options start around $13, though users should apply a pea-sized amount at night and moisturize to minimize drying.
