[acne] BBL treatment?

I've always had some acne, but it seems like the past 6 months or so have been significantly worse. It's red, cystic, painful, and nothing is working for me anymore. I've come across a professional in my area who does BBL treatments and the before/after photos of her clients are amazing. Has anyone tried this? It says sessions range from $400-500, but what I want to know is how many sessions does it take to see results? Does it really work? If so, how long do the results last for? I just don't really know what else to do at this point. I don't even want to leave my house.
