Neutragena makes a body wash that has salycylic acid in it. It will break down the oils that are clogging your pores and remove the layer of dead skin on the top of your skin. You need to get a back scrubber with a pouf on the end. It will make the wash foam and you won't need as much. Plus you can scrub your whole back with it. Most chain drug stores carry the neutragena or a beauty store called Ulta. Bath and body Works carries the pouf on a stick. Salycylic acid will not bleach out your clothes or towels . Do it every day and if you can leave it on for a few minutes while you wash other areas.
Proactive Solution - Deep Cleansing Wash is Great on body acne! I love that stuff...you can use it on your face too...has a great pepperminty smell and it got rid of my mild back pimples fast. Acne products though are very person specific. Some products work better for others.
