Procedure recommendations for jaw slimming? Considering v line surgery but concerned about limited, experienced surgeons (Photo)

I'm interested in vline surgery, but it's difficult to find experienced surgeons in the US (socal). While less risky procedures are ideal (less risk of botching, side effects), I'd like to get the dramatic results that are typical of Korea. I don't speak Korean, so traveling is not an option. Anyone have recommendations for the correct procedure or potential surgeons in LA/California? Thanks
