2.5% benzoyl peroxide formulation with minimal ingredients. Expensive. Has "scrub" particles that are potentially irritating. This is an excellent product; however, it must be used carefully because it is a scrub and potentially irritating to the skin. I (very gently) use it to wash my back and shoulders instead of applying 2.5% BP gel, and it seems to be as effective (and it is certainly more convenient) than applying the gel. Washing with BP may not have the same potency as using a gel, but it seems to work for me. (I actually leave it on my skin for a few minutes before rinsing it off). Because of the scrub, I think this product is inappropriate for the face. If you have moderate bacne, consider giving this a go if you can afford it. As a note, I use the DDF non drying gentle cleanser on my face (32$).
