I had severe acne from high school until my junior year in college...but i discovered methods and ways to clear it with ease. I'll give some general things I did, but feel free to ask me questions if you want.

1) i avoid any types of dairy, soft drinks (only drink water, occasionally juice like carrot juice)

2) I avoid junk foods, anything that is deep fried or even pan fried with vegetable oils etc.

3) I eat a lot of grilled chicken that I make ahead of time, you don't necessarily have to eat veggies to get clear skin

4) Only cleanser I use is Cetaphil, and that's not because it clears acne, it's because I have oily skin and it cleans it without leaving my skin dry as sand.

5) Avoid eating white breads and other bad carbs, but white rice doesn't affect me. However, white breads do cause acne for me

6) I avoid any types of legumes, beans, but that's just how my body reacts.
