After Accutane - Did it come back ?? in Prescription acne medications Posted July 27, 2010 Im 18 and have just finished my THIRD round of roaccutane with very long periods. First round - 9 monthsSecond round - 11 monthsThird round - 12 monthsThe doses were around average for my weight (73kg, was on 40-60mg/day). My dad is on a low dosage for life because of his cystic acne and it keeps it his under control. My acne was not terrible, just very persistent and each one lasted for weeks at a time. Everytime my skin has been perfect at the end of the cycle and was usually fine for a few months but then sloooowlly creeped back.I hope the last round lasted long enough to ride out most of my hormonal fluxes haha =)Good luck to everyone, but this has just been my experience.
