Acne
"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."
