What Is Benzoyl Peroxide?

Benzoyl peroxide is an organic compound that is well known for its acne-fighting properties. Used in acne treatment formulas for over 80 years, benzoyl peroxide can be formulated at concentration levels that vary between the ranges of 2.5% and 10%, though most often at the lower end of the strength range. Both prescription and over the counter acne treatments can contain benzoyl peroxide, which is applied to problem skin areas in a cream or gel solution that clears harmful bacteria from the pores.
