7 Dermatologist-Approved Products to Banish Blackheads

Dermatologist Dr. Hirshel Kahn recommended retinoids to unclog and prevent blackheads. "Some retinoids are over the counter, and some are prescription," he said. "Sometimes retinoids may be drying and need to be applied sparingly." For a prescription-strength retinoid that you can buy over the counter, try Differin Gel ($11), which contains a powerful type of retinoid called adapalene.
