Thank you for your question. Accutane (isotretinoin) dosing is based on an individual's weight, which is 1 mg per kilogram for a minimum of 4 months. Therefore, if you weigh 60 kg, then your minimum recommend total dose will be isotretinoin 60 mg per day for four months. But if you can only tolerate 30 mg daily due to side effects or lab abnormalities, then your therapy will be 8 months. Also, a side effect of Accutane is skin sensitivity and an increase risk in scarring; therefore, since your procedure coincides with Accutane therapy if you start now, then it would not be recommended to have your procedure, or you can postpone Accutane until after your procedure. I do not recommend starting Accutane and ending treatment early because the chances of acne recurrence is higher if you do not complete therapy. Either way, I highly recommend you consult with a board certified dermatologist regarding Accutane treatment and if you are a candidate. Take care and good luck.
