acne
"I've been taking Yaz for almost a year.  I had constant acne breakouts and very bad mood swings before taking Yaz.  Since then, my acne has cleared up and my moods are more balanced.  My periods are lighter and my breasts are fuller for a couple weeks during the month.  It took about 3 to 6 months for my acne to get better.  I am very happy with the product.  I have not noticed any side effects."
