How do I fix my skin?? Acne help please..?

OMG dude I totally know how it feels like! I'm 16 and now just suddenly getting acneout of no where! I suffered for about a year... My acne was severe, now it's clearing up. I've used pretty much anything and nothing ACTUALLY works but what you should do is eat less oily, sweet, and fat foods(snacks, chips, cookies, pizza, and what not). drink ALOT of water!( 3 to 4 times more than you usually do). I no longer use any products(they're just scams) except for just the daily facewash(2-3x a day). try not to use benzoyl peroxide because it makes your acne worse! Don't take any vitamins or those spot treatment, they make it worse and worse and you keep buying them! If none of my steps work after 2-3 weeks, go to the local dermatologist.
