"i&#039;m a 20 year old with severe acne on my face. i took 40 mg for the first two months and am currently on 60 mg. i am on my third month and am starting to see great results. 
some of the side effects that i&#039;ve had are very dry skin near my mouth and nose, chapped lips (especially on the corners), and sore shoulders.
(all of which i&#039;ve found relief for, thankfully. clinique dramatically different lotion for my skin, vaseline for my lips, and the occasional advil for when i am sore).
i still have a few cysts on my jaw and lower cheek but they are slowly disappearing. 
i have a lot of hyperpigmentation and scarring from years of severe acne but i am hopeful.
this medication is very expensive but i really feel like it has been worth it."
