I know you've tried many products but this one is definitely worth a shot, I use it, it's called BioClear, it's by Jan Marini Skin Research, it may be hard to find but check their website. The product has Glycolic Acid, Azaelic Acid and Salyicilic Acid. Also I would suggest getting facial peels at a derm's office. I have been using oral contraceptives (Estrostep FE), it's supposed to help with acne. It was helping me for quite some time but now the acne is once again appearing all over my back. It's quite frustrating! Hang in there. I'm a medical aesthetician(skin care professional) so if you have any other questions, I would be more than happy to help. Goodluck.
