Greetings Lexie,
Unfortunately you have a very difficult problem for which there is not one answer. Your best course of action would be consultation with a dermatologist to help you get the acne under control. For the pigment irregularities, your dermatologist can help but if they do not treat cosmetic issues, consultation with a facial plastic or plastic surgeon can be helpful. To control your acne consider either oral or topical medications. If you are looking for the high end medication for severe acne, consider Accutane. There are side effects and blood tests are necessary but it has a very good success rate. For the pigement irregularities, you can try topical hydroquinone bleaching agents or possibly IPL or TCA peel treatments. Again, consultation with an experienced physician would be necessary to determine what is best and help explain all of the risks of the procedures. Good luck.
