im 21. i took 2 accutane courses each 4 months long and at the lowest dose - 20 mg in the morning 20 mg at night- ive been off my 2nd course for almost 4 months now and not really getting any pimples/acne ..yet ...but i have some scarring which i think is from my initial course of accutane. prior to accutane, i dont think i was scarring at all. NOW, with that being said, im not sure, i was young and i didnt really even know what scarring looked like. i didnt really pay much attention or care as i picked all my pimples...accutane may have caused my scarring, but really if i didnt take accutane my acne could have gotten much worse and spread and gave me worse scarring in the end. so idont know, for everyone its different dude...dont look into peoples opinions and answers on here too much because everyone is different.
