Body Acne--What Can You Do About It?

I never knew you could have acne on places besides your face until I saw a man with acne on his back. I thought--how painful that must be! And embarrassing! And what do you do about it? And then recently I heard there is such a thing as body acne wash. I guess you use it like acne face wash. Acne is such a useless problem. Why do people have to get it? At least you grow out of it.But until then, you just gotta endure.
