I had sporadic bouts of acne for a while when I was a teenager. Not ridiculously bad but bad enough to make me self-conscious about it. Everything I got from my dermatologist either dried my skin out to the point where it would literally crack or it did nothing at all. Then I went vegan and my acne literally went away immediately. I'm not vegan any more (although I was for just over 8 years) and I'm not suggesting you take on a change of diet as serious as veganism - but changing up your diet a little bit will very likely help.

If you eat a lot of fatty, salty or fried food, cut back. Eat some fruit and raw vegetables, for ****'s sake! Stay hydrated. Too much caffeine will dehydrate your skin and cause your body to overcompensate by releasing oils, which it turn make you break out. Drink organic milk, as the overload of hormone additives found in typical milk will wreak havoc on your skin (and the rest of your body). Also - sugar substitutes are a common cause of nasty skin reactions and zits, especially in young people. And lastly, lay off the crystal meth. That **** might be fun for a while but it will make you ugly.
