What should I use for my skin?

I breakout often..nothing too serious but when I do it's big red pimples, I guess because of stress. Anyhow I also have brown spots from previous acne left. I've tried everything from clearasil, oxy, neutrogena, and spectro jel worked for a while but not anymore..also stuff like st-ives apricot scrub used to dry my skin alot. How can I get clear skin?
