Acne.org's Real World Take

May provide partial relief at higher prescription dosages. Comes with less side effects than the other two topical retinoids, tretinoin and tazarotene, but may also work ever-so-slightly less well. No retinoid is likely to be a game changer, but studies do show a partial reduction in acne.
