if your acne isnt serious, accutane is not the only prescribed medication available, there are others that are A LOT less strong like minomycin (which is an antibiotic) it doesnt so much as work to get rid of current pimples, but to prevent future ones. so for the best results you need to treat your acne both the inside and out so you may want to play around with spot treatments. find a routine that suits your skin type and whether you wanna go the whole nine yards, facewash, night and day moisturizer, scrub, toner, masks etc is up to you but i strongly recommend facewash, toner (no astringent) and even if your skins oily you must moisturize (if your skins dry it will overcompensate by producing more oil, same thing with overwashing) use something oil-free and waterbased. and water and exercise reeeaaally do help to flush out toxins. and i agree with changing your pillowcase every other night and taking supplements as well as using a separate towel for your face. oh and you dont have to blow big bucks on department store stuff, a lot of drugstore brands are good too.
i know a lot of people will disagree with me and say that you just need a healthy lifestyle but in some cases thats just not it, but im assuming the op doesnt eat junk food everyday and has a relatively healthy balance though.
