Hi, I am a 34 year old male who never had bad acne or oily skin. About six months ago, I started having very oily hair and face, mild to moderate scalp acne, and seborrhea (scaliness in my eyebrows and t-zone). I weigh 75kg and was prescribed 40mg of Accutane for 30 days. My question is, is this amount sufficient for a long term cure? Thank you
