"love this! i was a little discouraged at first because the magic number of 3 months didn&#039;t work for me. however when i hit 4 months all of my back acne was gone and my face had totally cleared up. i&#039;ve never seen anything like it. i still get the odd zit and for individuals who react well with yaz i find that acne can be caused by eating dairy products. i don&#039;t doubt if i cut milk and cheese out of my diet, as well as continued on the pill i would have 0 acne at all."
