Getting rid of mouth acne???


So I used to have a lot of acne all over my face, that was a couple years ago and I cleared it up with Accutane, but ever since then I still gets pretty bad acne around my mouth and chin. I wash my face every morning, I used to do it twice a day, but it started clearing up a little after I started only doing it every morning. It also will sometimes look like it's clearing up really well, but then later that day it'll go back to looking like a breakout. I use moisturizer as well, but not around that area of my face. I've tried 3 different kinds of face wash and it still won't go away. They all work great for every other part of my face except that area around my mouth and chin. I'm really confused. Any advice would be greatly appreciated and sorry this was long!
