Interesting to see this comment. She clearly had buccal fat removal. She probably did/might have done some jaw shaving too but it's hard to tell because her facial fat covered up her actual jaw line.
Btw she also did brow lifting, which changed the shape of her upper eye lid and gave her that winge
+ Nosejob.
Buccal fatpad reduction doesn't add much to looks, providing it's the right procedure to do and the surgeon does it well. Sometimes it makes you go back in looks.
That area isn't a very important facial area. If you do too much, you might get a Victoria Beckham face, which makes her look like a drug addict. Balance is key.
The shadows you see on some (model) faces, the 'sucked in cheeks' is usually caused by portruding cheekbones + jaw area and probably part of the chin too. You don't need to have it to be good looking. But some people have bloated cheeks, I guess buccal fatpad might work in those cases.
She went from a convex nose to a concave nose. Although it was overdone imo and it looks slightly fake (she probably had two or three nosejobs), it was probably a good decision and made her a career. It also doesn't look fake enough to be a distraction. I see women with overdone nosejobs, which look too fake, but she got somehow lucky it didn't ruin the natural beauty.
