I certainly wouldn't recommend birth control pills for acne given the mounting body of research suggesting a link between popular oral contraceptives and breast cancer. However, that's just one man's opinion.

That decision should be made factoring in the input of only you, your daughter, her father and most importantly her doctor.

You may want to have a look at this article about probiotics and acne: http://blog.pamelaegan.com/blog/post/2010/12/27/Vitamin-D3-and-Probiotics-Can-Help-Fight-Acne.aspx

For the sake of full disclosure, my mother, a highly acclaimed medical professional (nurse practitioner, to be specific) who has more letters appearing after her name in the form of credentials than her name consists of, is the author of the article referenced above. That said, I don't know of any other articles on the topic, and am only sharing this one because I genuinely believe it may help.

There is credible scientific data underlying the association of probiotics and acne prevention (as is also the case with probiotics and yeast infections). Basically, much acne is bacterial in nature, and the extent to which one's skin (and other parts of the body) are susceptible to bacterial infections, topical and otherwise, is in some way associated with floral balance inside the digestive tract.

I'm not claiming to understand how it all works well enough to explain it in detail. But from all I've read, I do understand the functionality, even if I cannot explain it myself coherently, hence why I referred you to my mother's article above.
