Moderation and regularity are good things, but not everyone can sleep eight hours, eat three good meals, and drink plenty of water a day. One can, however, still control acne despite one's frantic and unpredictable routine. Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
