Drospirenone / ethinyl estradiol
"I've taken Yaz for 3 months now and it has cleared up 90% of my acne. All I have left are some tiny clogged pores which are clearing. I have adult acne and tried every OTC, prescription, and expensive creams, microdermabrasion etc and nothing worked. Previously intolerant to the pill, but on Yaz I'm calm, happy, no problems. Be warned, the first 6 weeks your face will look horrendous, worse than ever,  but it gets so much better."
