One month isn't really enough to see any real difference. Even when I took yaz and yazmin which are androgenic (stronger at suppressing oil than ortho-cyclen) I didn't notice a reduction in my oil until about 3-4 months in, and it wasn't completely gone until 6 months in. Since ortho-cyclen is not an anti-androgen, I wouldn't expect to see a complete reduction in oil, though. I think only yaz, yasmin, or spiro could do that.

With Loette I noticed a difference in a week. But then when I had my sugar pill bleed my skin got really oily again. I agree with Paigems, give it several months.

I agree with everyone else here when they say to wait several months, but some birth controls definitely do help with lessening oil production. I am currently on Yasmin and it is doing wonders for my oily skin! It isn't quite "normal" yet, but I've been enjoying significant improvement. Keep at it and give it a few months to kick in, you'll get there.

My oily skin never stopped.. not even with diane 35. I don't really mind. Without pill it's SUPER oily, but on the pill it's ok. When I use primer and make up setting spray when I go out it stays pretty much matte.
