"i have been on yaz for hormonal acne for about 3 years now. let me just say the first two years were awesome. no chin breakouts, less oily. now for some reason it is no longer working. i am getting painful cysts again around my period. i thought it was temporary but i started noticing it in december and it is now september. i&#039;m nervous to get off of it for fear it will be worse. it worked for me for some time but now i have to find something else."
