Benzyl peroxide
Benzyl peroxide is available over the counter and has been used to treat acne for at least 50 years. This agent can kill the bacteria and also acts as an abrasive agent. It is the only topical agent that is most effective against the bacteria which is commonly found in acne pustules.
Benzyl peroxide is available in various concentrations (2.5 to 10 percent), although there is no evidence that using higher concentrations result in better treatment. The water-based formulations cause less drying of the skin than the alcohol-based preparations. Benzyl peroxide gels are applied once or twice daily.
The most common side effect of the agent is skin irritation. This effect occurs more often at higher concentrations and tends to decrease with continued use. Some individuals develop contact allergy. All patients using benzyl peroxide formulations should test the skin to make sure they do not have contact allergy. The drug is a strong oxidizing agent and can irreversibly stain clothing and linen. The drug is best applied in the morning so it will be dry by night time and so the risk of staining is avoided.
The big question is does this chemical work? and the answer is a NO, it is close to crap. The majority of individuals who have acne remain dis-satisfied with benzyl peroxide.
