I had a client that suddenly developed cystic acne and she came to me, of course, because she wanted to know how to get rid of it. The first thing that we talked about was diet. What was she eating that was causing the problem to begin with? Many of you may not know, but diet directly affects your skin. If you're eating something that your body can't digest, the body, as an emergency solution, will try to push it out through your skin. After all, your skin is just a filter.
