I had cystic acne all over my back and face that never went away. Ever since I was 13 I had it. I tried EVERYTHING, Tetracycline, Doxicyline, Benzacaine cream, and tons of other stuff. Nothing ever worked. So I did this as a last resort, my own dermatologist said he wouldn't prescribe it to because I wasn't a candidate. So I went to another one who said I was perfect for it since nothing else has worked.
It took 5 months and I've never had anymore breakouts like that. He said I may have a random one or two once in a blue moon and he was right! No scars. Only some dry skin, and no mood swings.
It was awesome and I'd highly recommend it to anyone who is ready to be done with nasty acne. I did it at 21 and now at 28 I look and feel great!
