We've already covered salicylic acid—a great tool for clearing skin—so now we're diving into an equally powerful and important pimple-fighting ingredient: benzoyl peroxide. While salicylic acid exfoliates, benzoyl peroxide actually dries out the skin, potentially eliminating blemishes overnight. But what strength do you need? Which formula is the best? How do you apply it? Read on for answers to all of the above.

This potion is as no-frills as it gets. It packs 2.5 percent benzoyl peroxide, but is very effective on pimples. Ideally, apply it to clean, dry skin before bed. If necessary, however, you can use it up to three times a day.

Clinique's medium-strength formula, with 5 percent benzoyl peroxide, kills bacteria and controls oil with less drying than a maximum-strength product. The unique solution soaks right into skin, making it perfect for zits that have risen to the surface.

No, it's not a teenage flashback, Clean & Clear is still relevant post-graduation for one good reason: this tube packs the maximum strength allowed for benzoyl peroxide. We recommend using a 10 percent formula on your worst pimples and anything you want to disappear overnight.
