"my dermatologist prescribed sumadan to me for my acne. for the past 3 weeks i have been using it every night and day and have seen great result. my skin only has a few minor pimples but for the most part it&#039;s smooth and clear. however, recently the wash a begun to dry my skin and sometimes even burn it. i&#039;ve decreased my usage to once a day which has helped but i would not recommend this product to anyone with overly sensitive skin."
