What to do if i have mild acne how clear will my skin get of i do this?

Scientific Rx: Try a salicylic acid rinse as tolerated. If this does not clear you, a retinoic acid derivative and/or topical benzoyl peroxide. Your personal physician is a good source of advice as well. Nobody has perfect skin, and truth be told, nobody else really cares 'how clear' you are. You do need to keep acne under control as it's a sign of poor self-care in this day and age. Best wishes.
