I had severe acne for many years. I tried a lot of different things, but I discovered that I had a personal trigger - if I ate a lot of carbs and fats together combined with irregularity of my bowel movements, I would break out. So I basically cut out sugar and took steps to make myself as regular as possible. Acne completely disappeared. I didn't really lose weight (I was never fat) and I didn't really get too much healthier since I still eat a lot of "non-sugary" junk food. But even now, around the holidays when there is lots of candy and unhealthy food, if I eat too much sugar and don't have regular bowel movements, the acne comes back like it was never gone. It's crazy, but I'm approaching middle age and this is still a thing. And this isn't something that applies to other acne sufferers I've met, either. This is my trigger, they have theirs.
