Acne.org's Real World Take

A way of using benzoyl peroxide in combination with the topical retinoid, adapalene, that studies show works a bit better than benzoyl peroxide alone. Comes with side effects for the first weeks and can bleach fabric. Note: When used correctly, benzoyl peroxide on its own can completely clear the skin.
