Back acne has, in so many ways, been a plague on the human acne condition.  After all, it’s a lot harder to reach back acne, let alone actually put treatments on it or otherwise, because you can’t directly see it, and frankly oftentimes you can’t exactly reach it as well as you would be able to reach other types of acne.  In short, it happens because the pores get clogged with oils and bacteria, just like any other.  Why it gets clogged nobody actually knows.  But anyway, you can avoid acne in some ways by when you work out, remembering to wash the sweat off and really scrub it to exfoliate relatively immediately.  You can use some scrubbers on a stick for this purpose.  But you also should remember not to wear too tight of clothing that would cling to the skin when you happen to be working out.  This only aggravates the problem and effectively makes it far worse than it actually has to be.  In addition, you have to be sure that you are using a good body wash.  Frankly, most aren’t likely to use a good moisturizer on the back, let alone a lighter one that won’t actually clog the pores.  So your body wash should be meant to do that job while also cleansing your skin quite effectively.  These simple steps will often help you to treat your back acne and prevent more from occurring effectively speaking.
