acne
"I have been taking Yaz for about two months now.  I stopped taking birth control about two years ago and started to break out with acne horribly.  I was on the patch and gained about fifteen pounds.  I lost all of that weight and now am 117lbs again.  I was worried that I would gain weight after losing it so my dermatologist told me to use Yaz. Yaz has been wonderful.  I have not broken out severely, maybe one or two on my chin.  It is completely fabulous for acne and for birth control."
