Hi Jewels, the person who will find the universal cure for acne will probably be a trillionaire. Why? Because it's so damn hard to find the cause for every person.
For some a simple cream will fix everything, for others it will mean diet changes, exercise changes etc.
I started getting acne around 12, and I managed to start outgrowing it now at 24. What does this mean for you?
Try everything, and don't give up. Analyze your regimen and your lifestyle. Also take into account the fact that you're exiting adolescence, which can help.
Your body is made of the things you eat. That is usually the starting point. Give it the things it may be lacking or the take away the things it doesn't want.
It's all big slush of hormones, bacteria, cells and things which interact together, then puberty unbalances all that. Sometimes it rebalances itself, sometimes you've got to do it yourself.
And don't listen to the negative guy, I think he's just having a bad day.
