Just to be safe you might just want to go to the dermatologist if you can, just to maybe stop the problem before you get too much scarring damage. Last spring, for some weird reason, I started getting terrible breakouts . I was almost 22 and had never had bad skin, even during my teens, so it was totally weird and frustrating to start breaking out like I did . I finally went to the dermatologist, and it turned out that I had acne, so I had to go on a couple different kinds of prescriptions and eventually it cleared up completely . But I really wish that I had gone sooner, just so that it could've been taken care of sooner. I don't care if you are fat or skinny, nobody wants bad skin, so get it checked out, it might not have anything to do with your diet.
