Does Prostrolane Inner B really work IN the face (instead of just under the chin like Kybella)?

I have a small dat pad in the jowl area. I have already had 2 mini liposuction treatments in that area, which caused me a lot of scars (luckily I don't see them but I can deel them with my tongue in my mouth). I don't want to put my face through another lipo. My cosmetic doctor told me that a relative new injectable called 'Prostrolane Inner B' would help. But I can't find a lot of info on it ter, not even here on Realself. Can anyone tell me about their experience with this? Thank you!
