This specific kit offers advanced acne care so you can take back control of your skin. The kit’s cleanser and treatment contain benzoyl peroxide (BPO), an ingredient known to kill problem-causing bacteria that can lead to worse acne. If you're breaking out more often, have more than the occasional pimple, and your pimples are typically more red and inflamed, BPO may help clear your skin. Keep in mind that BPO is tough on acne but can also sometimes be a little tough on skin. Using the Clean and Clear brand's oil-free hydrating moisturizer can help reduce dryness. It's also a good idea to use BPO products with a white towel, because BPO is known to bleach some fabrics.
