"i&#039;d been on some bipolar medication for a few years that for the last 10 months or so was increasingly causing mild acne. i tapered off those meds but the acne persisted and even got a little worse. my doctor prescribed adapa/benz two weeks ago and i&#039;ve already seen a massive improvement - it&#039;s almost completely gone. i did go out in the sun and wind one day and even though i had a hood up most of the day, i still got a burn that flaked off in a couple of days. i see from reading the reviews that the people with negative reviews mostly aren&#039;t following the instructions with respect to sun exposure or lesions. make sure you follow the directions! if you do, you will probably have good results."
