A drugstore retinoid that does the job without the drama: the experts who reviewed it say it clears breakouts, blackheads and post-acne marks, and many find it gentler than other retinoids. It's still a retinoid, so a pea-size amount at night, eased in slowly, suits sensitive skin best. One camp finds it too mild for stubborn hormonal acne.
