"Benzoyl peroxide is a powerful medicine that can dry a large pus-containing pimple or a deep, red cyst in just a few days. If you need full-strength acne busting medication and don't want to have to visit your dermatologist, this medication will help you," says Dr. Davis. "The 10 percent is maximum strength and ideal for oily skin, but 5 percent or 2.5 percent strengths are also available and are less potent for more delicate skin." This product should not be combined with retinoids, vitamin C, or AHAs. If you want to use them, alternate every other day or morning/evening.
