i used to have really bad acne. My advice would be to forget about stuff that may or may not work for you, like proactive and go to a dermatologist. I went to one when i was 18, at the time my face was riddled with acne and i was so embarrased cus i had so many black spots i felt like a leopard, the dr prescribed Roaccutane, which is a 3 month series of pills(or six months maybe), it completly gets rid of the scarred layer of skin and changes your system so you dont produce as much oil anymore. After that treatment i had fantastic skin, so smooth and soft and to this day,(im now 31) i only ever get maybe one or two blemishes at the beginning of my period.
ive always had compliments about how nice my skin is and people refuse to believe i ever even had acne, till they see my old high school pics..
That treatment though does have some side effects, some people reported going into deep depressions, but it didnt have that effect on me and it was so worth it, a real God send!
so my advice, dont waste money on stuff that may or may not work, go see a good dermatologist.

Hope it works for you.
