the bottom line is that it worked for me. (i'm actually on estelle, which is a brand of diane, it's just cheaper!) i was skeptical, i'd tried everything, i had also tried loette, another form of pill for acne. i have been on it for just over two months now and my skin has drastically improved! i had terrible hormonal chin acne which was really, really red, and now i have no new noticeable pimples, only the bit of scarring that's going away now :) couldn't be happier! give it a go!
