I have taken a complete 2 courses of Accutane in the past 5 years , I still have some minor breakouts I'm thinking of taking it for the third time as it's the only thing that help my skin so far, will I take it for a 6-8 months (full dosage) like usually or just a couple of days a week ? Will it cure me completely this time? Please if you could explain the process in depth I'll really appreciate it
