is back acne the same as facial acne?

Sometimes I have weird thoughts. This morning's thought was "Would a normal acne treatment work on back zits?" Yeah, I know, it's a gross thing to think about but I can't help it. My mind wanders into strange territory sometimes. And, really, the same thing that causes facial acne should be the same thing that causes back acne, right? So, in theory the treatment should work the same on either place on the body. Right?
