Botox and Kybella

I have heard quite a bit recently about dentists offering Botox services and now even Kybella. I realize whether or not a dentist can offer this in their practice will depend on their state but I'm curious how does one go about ordering these materials? I doubt companies like Henry Schein are providing it so how exactly do we order it once we are certified to provide it?
