Drospirenone / ethinyl estradiol
acne
"I started on Brenda and it made my mild acne worse. I switched to Yasmin and it cleared it right up, however, 5 months on and my face has started feeling greasy and I'm developing small pimples. I don't know if it's just this hot dry weather. 
Ps: I stopped doing a 4 step cleansing and treating routine as I thought I had no need. So perhaps it's a combination of those two factors."
