hi all. I'm a 31year old woman. When i was 21 i went on isotane (accutane) and had fantastic results and mainly clear skin until a year ago. I went on duac and it worked for a couple of months then stopped. I am off to the dermatologist to hopefully go back on accutane on monday. ..would i be best to stay on duac as well to make it work faster ot is it a waste of time. .. thanks so much. Cant believe im still dealing with acne at my age
