Jan Marini's Benzoyl Peroxide 10% is the medication of choice for treating acne. The benzoyl peroxide dramatically clears up the appearance of acne lesions and also prevents P. acne growth at the beginning of the acne process. This preparation minimizes dryness as well as irritations while providing maximum measurable effectiveness. It is very effective in minimizing blackheads and in the prevention of the formation of new lesions. It is especially suited for the acne-prone individual.
