Body acne is just like facial acne. Many people also call it a genetic disorder. If your parents have suffered from body acne, chances are that you will also suffer from the same. It's also noted that people who have suffered from facial acne have also encountered body and back acne at some point in their lives. The only difference between body acne and facial acne is that the skin on the body have bigger pores than the skin on the face and thus body acne causes more damage than facial acne.
