i was on accutane back when i was 18 or 19 and that shit absolutely works. however, it's brutal. it dries you the fuck up. i remember getting nose bleeds on occasion, my lips looked like hell as i was always peeling and chapped, i had to moisturize and wash my face like 3 times a day cause my skin was honestly starting to wrinkle and shrivel up like a prune. you gotta do that shit for like 6 months too.
but i guess in the long haul it's worth it. never had acne problems since. granted, growing out of that teenage oily hormone phase probably helped with that too. even when i exercise now, i dont stink like a mofo. teens are just greasy and smelly in general. your body is all fucked up and doesnt know what to do. growth spurt lankiness, hormone surplus, random boners, voice cracking, patchy facial hair.. man. glad that shit's in the past, hahahaa.
GOOD LUCK WITH THAT!!
