Roaccutane was the only thing that cleared my acne up. Normal side effects - dry skin, chapped lips, easily sunburnt etc. but other then that, 2 weeks after I stopped was back to normal, but with a hell of a lot loss acne.
Wish I did it years earlier instead of wasting 3-4 years trying other useless stuff.
Go and see a good dermatologist, if you're in brisbane I'd recommend Westside Dermatology - won't have to wait long and they're all awesome. I had Dr. Manoharan, good bloke.
