Interesting example to bring up. At first blush, to my eyes, it's as if she lost fat between her eyes and upper cheeks. Am I being tricked by the wider malar cheek area post op?
I'd personally be more curious about how implants look as you actually age.
EDIT - looking at this harder, it kind of looks like she also had buccal fat pad removal? The area under her malars appear less full vs pre op.
