acne
"My doctor suggested I go on Yaz after a good 8 years of being on a previous pill and basically experiencing acne the entire time.  Anyway, I've been on Yaz for a month. I'm glad I read reviews before because I probably would have given up and fully entered a hermit life if I didn't know that a major breakout the first month or two is normal. I have gotten acne in places I've never had before - along my jaw line, even on my neck. It's terrifying and I'm only hanging in there based on the people that swear by month 3 is gets better. However, I will say, I am happy with having experienced no other side effects. Weight has never been a problem for me, but I actually lost 5 pounds. Here's hoping that month 2 and 3 brings better luck!"
