Considered the most effective over-the-counter choice for a topical antibacterial agent in the treatment of acne.
The amount of research demonstrating the effectiveness of benzoyl peroxide is exhaustive and conclusive. Among benzoyl peroxide’s attributes is its ability to penetrate into the hair follicle to reach the bacteria that cause the problem, and then kill them—with a low risk of sensitivity. It also doesn’t pose the problem of bacterial resistance that some prescription topical antibacterials (antibiotics) do.
Benzoyl peroxide solutions range in strength from 2.5% to 10%. It is best to start with lower concentrations because a 2.5% benzoyl peroxide product is much less irritating than a 5% or 10% concentration, and it can be just as effective.
