Hmmm....
I get them all over.
Bathe properly (some don't get this).
I also tan regularly (helps kill off body acne).
Most pimples I break and let the junk out. They say that's bad to do, but I find it lets the junk out and the blemish heals faster. Otherwise it turns into this monsterous zit that looks horrible, makes more of a mess when it breaks, and takes longer to heal.
