I'm currently on my 8th week of roaccutane. The first 4 weeks were 30mg and seen my skin get worse. After week 4 I started on 70mg and now have seen my skin get much much worse. My acne was loacalised to my chin and chest but now I have it on my cheeks, neck, chin, forehead and jaw. Why is this happening and when should I get concerned. My lips are so dry they constantly crack and extremely painful. I can't eat in public as my skin around my mouth cracks and flakes with the movement of eating.
