The only thing that helped me was diet. When I cut excess sugar out of my diet I saw significant improvement. Now I don't eat dairy and am on a low carb diet. It's really helped and if I stray from my diet I do notice more acne popping up - even at 24 years old :/ . That's what worked for me though, which isn't to say it will work for everyone. I think getting to the root of the problem is the best way but obviously, natural oils and the like will help while you're trying to find that root cause. And the stuff that most people put on their face is absolute garbage! Good on you for spreading the word! Acne really effected me and my self-esteem through high school.
