"i was on accutane when i was 16 for about 8 months. i first took 40 mg a day then he moved it to 80. the only negative side effect i had was dry lips. my doctor kept me on it longer because i have extremely sensitive skin and can&#039;t use topical things like benzoyl peroxide because it makes my break out in skin rashes.  i have had clear skin up until about six months ago. i am 24 so that&#039;s 7 yrs of clear skin. i am going back to my dermatologist this week so hopefully he will put me back on it because it is amazing. i would seriously stay on it forever if i could."
