Benzoyl peroxide for acne treatment

Benzoyl peroxide is an effective and inexpensive form of acne treatment. It is usually applied over the affected areas in gel or cream form, in concentrations of 2.5% increasing through the usually effective 5% to up to 10%. Research suggests that 5 and 10% concentrations are not significantly more effective than 2.5% and 2.5% is usually better tolerated. It's important to take note that Benzoyl Peroxide kills bacteria, but does not increase the body's resistance to it, nor does it affect sebum production. Therefore, it is important to continue treatment even after the desired results have been achieved.
