water, fruits and veggies and good hygeine are the main things to stop acne. Oh yeah i think waking up early with enough sleep at night helps too.
Ive heard that the water u use to wash your face can cause acne and even flaking on ur scalp.. because of the metal particles in it.. try checking out nsa certified water filters if u want to buy a filter.
hahahah! i don't think there'd be metal flakes unless ur pipes are like corroding and u live in a slum.. wouldn't the flakes just work as a scrub?...lol
surgery.. haha jay kay, water sleep, and keeping ur face clear of oily stuff and avoid touching ur face w/ your palm very often, cuz yeah palm is oily sometimes n dirty, this is my remdy, but i get acnes every so often still and im 18
