Topical Antimicrobials for Acne
Most dermatologists prescribe topical antimicrobials to inhibit the P. acnes population that cause acne. Usually, this is most effective for mild to moderate acne but it can help in severe cases as well. Topical antimicrobials can either be used alone or it can be combined with other oral or topical medications. Some of the most popular topical antimicrobial includes:
Azelaic acid – this is a naturally occurring substance on your skin. The azelaic acid is effective in getting rid of mild and moderate non-inflammatory or even inflammatory forms of acne. Many believe that this works by reducing the abnormal shedding of the skin so inflammation is reduced. Azelaic acid can be used for years because most people have good tolerance for it.
Benzoyl peroxide – it works by killing P. acnes. Its main downside is that it does not have anti-inflammatory benefits. Benzoyl peroxide is available in various forms including lotion, cleansers, gel, creams, and soap. A lot of anti-acne products include benzoyl peroxide because research shows that it can enhance the effectiveness of other medications.
Erythromycin – it fights against a wide spectrum of bacteria. Topical erythromycin is proven to be effective in treating acne because it has antimicrobial and anti-inflammatory properties. Usually, it is combined with benzoyl peroxide for best results.
