"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."
