I agree with Dr Winston Lee.
Oral Isotretinoin is one of the most effective treatments for cystic acne. Through my experience with oral isotretinoin, most patients do not have a recurrence after their first course of Isotretinoin. And even if they do have a recurrence, it is usually milder.
You should consider other adjunct treatments like chemical peels, lasers and hydrafacial to reduce comedonal acne and clogged pores.
