Ethinyl estradiol / norethindrone
"I started taking Loestrin 24 to prevent pregnancy, not really knowing that birth control was supposed to clear your acne. I was considerably surprised when my skin cleared up [even on my back, which has always been a trouble area]. The first week or so was kind of rough but once I got past that, I felt incredible. I didn't experience any real weight gain or loss but I think I might have gone up half a cup or a whole cup size. I definitely love Loestrin."
