acne
"I took the max strength two times a day for 5 months when I was 17 and it was well worth it.  Around the 2 month mark my acne got worse but then around month 3 and 4 it was completely gone and has never returned, the only time I get a pimple now is when I have an ingrown hair.  My suggestions are to keep a tube of Vaseline with you for your lips, stay out of the sun, and make sure that you don't give up early on the treatment because you think your acne is getting worse."
