How can I convince a lip plaster injector to use Juvederm, Voluma or Volux in my lips?

how can I convince a lip plaster injector to use juvaderm voluma or volux in my lips? I’m someone who has filler in the past and when I’ve healed I didn’t retain a good amount of volume it would look like I never even had filler. Should I just tell her I’m aware it’s not usually used in lips but I really want dramatic volume and I’m signing off on it and am aware of what I’m asking? I feel like for the price of fillers I need to be seeing a big change that fits the aesthetic I want.
