Benzoyl Peroxide 5% and 10% strength is the medication of choice for treating acne. Benzoyl peroxide is currently recognized by the American Academy of Dermatology as being one of the most effective antibacterial agents proven to significantly reduce the presence of P acne bacteria (the bacteria believed to play a primary role in the inflammatory aspect of the acne process). Many physicians and researchers believe the benzoyl peroxide, use in conjunction with glycolic acid, is a potent toot to achieve dramatic clearing of acne lesions and prevent changes within the follicle associated with the acne process.
