Water is great for u but it has no connection with acne :) acne causes scarring so it's best to have it treated from within rathar then trying out 101 topical formula's.. always go to a reputed derm or sumone u trust.For the time being use an antibacterial/medicated facewash.. and a tea-tree astringent/toner as well. Even oily/acne prone skin needs a moisturiser (a water-based one)
