Will birth control help lower testosterone levels?

I have a lot of facial hair: on chin, side burns, and even coming out my nose. I have to "cream" off this hair every week. I'm a bit tired of it. I'm pretty sure the cause of this is high testosterone levels. Is there something I can take to balance my hormones... maybe take an estrogen supplement or something? I'm only 20, so it won't be for menopause or something like that.
