Benzoyl Peroxide 5% or 10% strength is the medication of choice for treating acne. Benzoyl peroxide is one of the most effective antibacterial agents that significantly reduces the presence of P. acnes bacteria.

Used in conjunction with a Skin Care Management System, Benzoyl Peroxide 5% or 10% can dramatically clear the appearance of acne lesions, and also prevents the P. acnes bacteria from feeding on buildups of dead cells within the follicle at the beginning of the acne process. This preparation of highly micronized benzoyl peroxide and specialized non-comedogenic emollients minimizes dryness and irritation, while providing maximum measurable effectiveness.

    Comments about Jan Marini Skin Research Benzoyl Peroxide 10% Acne Treatment Lotion, 4 oz:

    I have struggled with problem skin for many years and this is the best system I"ve ever tried. Other products helped somewhat or not at all; this is the only system I've tried that completely eliminates the problem.
    I use the peroxide wash in the morning and the bioglycolic cleanser at night. After massaging around, JM has you use a damp washcloth to remove most of the cleanser, then rinse. I think that may be an important step. Overnight I use the BP 10% lotion (start with the 5% if your case is not too bad). During the day in summer I use the Bioclear face lotion; if I'm still feeling dry I use LaRoche-Posay Effaclar M over it. In drier winter air I use the Bioclear face cream.
    My face simply never breaks out anymore. The BP products are no doubt the most helpful with acne, but the Bioclear products really do seem to help unclog pores and lighten discolorations. (I had a biopsy on my face last year which left a pretty noticeable dark area --- it is almost completely gone!)
    I have been fighting this problem for many years and I've tried just about everything else --- this is by far the most effective system. Highly recommended.
