Wash your face with sugar to get rid of acne marks. Wash your face with white sugar and a little water three times a day. Specifically, after washing your face with facial cleanser, put a little sugar on your palm (medically speaking, sugar is good for wound healing), add a little water to rub it (to prevent it from being too irritating and allergic), and then rub it on your face. After about one minute, wash it with clear water.
