Does proactive work??

I suffer from a lot of breakouts and no matter what I do they don't stop. I use steam rooms/sauna's and even sunbeds... yet I've stopped using sun beds because of the side effects. However in all fairness the sun beds did clear up my breakouts. I've heard about this proactive brand and I'm wondering whether it's any good? Can you buy this over the counter or is it only available via delivery? Also please if any one could give me advise on lifestyle solutions to naturally ease off these breakouts I'd be very grateful :D
