I don't know about that particular birth control pill, but for me birth control pills make the biggest difference in my acne.
Are you seeing a dermatologist?
For cystic acne, it's good to use a vitamin E lotion to prevent scarring, but only put it on the places you need to because supposedly it can clog pores. I've never found it to clog my pores, but people say it does, and with cystic acne you should always be careful.
