I have been getting acne right along the sides of my mouth down to my jaw for about 4 years now. I have tried literally everything topical you can image from over-the-counter prescriptions to natural solutions like apple cider vinegar. I have even tried multiple oral treatments as well, but neither of these have worked long term, only short term. It isn't small, manageable acne either, it usually hurts quite a bit, and every once in a while I will get a cystic pimple that will last a good long time. I drool a lot when I sleep, and I have always wondered if this could cause it. What do you think? and what would you recommend I do?
