How to get rid of acne?

I've suffered from acne all throughout high school and have tried all sorts of things from diet changes, medications from dermatologists such as Retin A, oral antibiotics, birth control pills, I'm currently on Proactiv, and nothing is working. I'm in college now and am just sick of it. I'm looking for a more natural approach to getting rid of it for good because I'm a little uneasy about accutane. I've read about the B5 acne treatment, but I don't really have very oily skin, if anything it's dry, so I'm wondering if that method is likely to work for me? Anybody have experience with this? I've also thought about acupuncture but there isn't a lot of research about this either so I'd love to hear from people with opinions on that. Any other suggestions I can research?
