Drospirenone / ethinyl estradiol
"I am 35 and I have suffered from acne and other hormonal problems for the last 9 years.  I was on allese before that and had minimal break outs.  When I was pregnant, both times my skin was flawless which indicated that it was definitely hormones.  I have not had any success clearing acne using topical, washes or any other specialized skin treatments.  I have been on yaz for nearly a week and am already seeing great improvements in my skin.  I wonder if it works for acne when the cause is truely hormonal.  I don’t think this is all in my head because others have noticed my clearing skin too.  I do work out regularly and eat pretty well so don’t know if that helps.I will update as time progresses."
