Benzoyl Peroxide

Benzoyl peroxide is an antiseptic that reduces the acne-causing bacteria and has been noted to be the most effective acne fighting ingredient without the need for a medical prescription, generally available at strengths of between 2.5-10%. Inflammatory acne is best suited to benzoyl peroxide to stop the breakout at its source. It works by penetrating the skin’s pores and releases oxygen, which helps to kill the bacteria that cause acne. It also helps to dry out oil, further improving acne. However, it also has some drawbacks, it can be quite harsh on the skin, causing dryness, redness and irritation and can lead to bleaching of clothing and hair, so it is important to be allow it to fully absorb before coming into contact with fabrics. Rarely, benzoyl peroxide can cause an allergic reaction.
