acne
"I have been on Yaz for a year. I was prescribed Yaz by my dermatologist. I have lots of clogged pores, very oily skin, and would get big zits on my chin that were not only ugly but painful. Yaz helped with the painful chin acne but not completely. It also helped my oiliness go down but not enough. I am on Accutane now and cannot wait to stop taking Yaz. 
My period is still heavy, I think it helped with PMS. I spot on this a lot. I also skipped the white pills this month in order to not have my period and have had my period for an entire MONTH. Obviously my body didn't respond to that well! I had an increase in appetite, gained twelve pounds. Also I am tired ALL THE TIME and feel moody."
