Can I get a slimmer and more V-line-shaped face with buccal fat pad removal? (Photos)

My name is Giang, I'm 18 years old and weigh 61kg. My face has always been so round even though my facial bone structure doesn't say the same thing. I've done some gym and brought a Jawliner (which is something that you chew to get a better jawline and lose face fat) but it seems like there's nothing I can do about the roundness of my face. So buccal fat removal has always been my concern and I am wondering if it can get me a slimmer face or a more V-line-shaped face!!! Thank you!
