acne
"Like a couple other users have mentioned, I started out on a small dose and this drug cleared my acne within two weeks.  I am 43 and have been on this medication for 4 months, after 20+ years of failure to control my acne.  I have tried everything.  I had moderate acne with constant blemishes and cyclical nodular breakouts.  I was also always red and so oily that my face would look wet.  Now my skin looks like I've never had a pimple.  I take 50 mg a day and recommend talking to your doctor about starting on a low dose like this.  I have had zero side effects and am nothing short of thrilled with the results."
