My skin is a lot dryer. I no longer have a layer of oil and shiny forehead by the afternoon after washing my face in the morning. My skin actually feels like it gets dryer throughout the day as the moisturiser wears off. So far the only side effect is minor peeling of the lips and a dry mouth. This is easily corrected with lip balm and drinking water. My skin does look thinner, and I can see the lines in my forehead slightly more now. I still get breakouts of small spots, particularly on the back of my head, but only one to two cysts. My skin does look better than it has done for a long time. So far so good, hoping to up the dosage to 40mg in the next. Praying that one day I'll wake up without a single pimple.
