After all these years, this substance is still found to be the most common compound in acne skin care products, because of its efficiency. Most doctors and dermatologists will recommend some OTC (over the counter) medications or prescribe some benzoyl peroxide creams, if you have mild to moderate acne. More severe cases will usually be treated with some other substances and products.

Consult your dermatologist about the possible treatments and then decide the best therapy for your acne. Ask your doctor about potential problems when using products with benzoyl peroxide and follow the recommendation or prescription.

Benzoyl peroxide, as the chemical anti-acne ingredient, will introduce oxygen to the pores, decreasing the number of present bacteria and reducing the acne. Only problem might be the duration of the treatment, because, once the treatment with benzoyl peroxide is stopped, harmful bacteria might grow again and cause acne. Consult your dermatologist about the period of use if these benzoyl peroxide products, for the prolonged use may be the cause of some side effects.
