Would I benefit from V-line surgery or should I consider a different procedure? (photos)

I’m 22 and I hate how wide/large and rounded/fat my jaw looks. I want a sharper definition and slimmer, V-shaped jaw. I was considering getting a V-line surgery, but I’m not sure it’s the right procedure. I’ve heard that getting it at a young age can cause eventual sagging and you can end up needing a face lift because of jowls and I don’t want that. Some people have suggested masseter botox or buccal fat removal, but I think the problem is my bone since my mom has the exact same face shape.
