Ethinyl estradiol / norethindrone
"I started taking this because my previous birth control was on backorder at every pharmacy. I've had acne for about 5 yrs & I've tried everything but accutane, but to no avail. I accepted that I was going to have to deal with acne. 
I'm entering my third month on Junel now and have noticed a drastic difference in my skin. I was a little bummed by Junel at first because I was having regular spotting (I'm a period skipper), but now that I've seen this change in my skin I think I'll deal with the spotting. It was an accidental benefit, but I'm very happy with it. Can't attest to the effectiveness of pregnancy prevention bc I always use condoms."
