How to lose weight in your face???

I am so jealous of girls with really defined jawbones and thin faces!

I'm not fat by any means. I'm like 115lbs, and about 5'4" in height. But I feel like my face is fatter than it should be. I also have a really short neck which I feel like draws more attention to it.

Are there like specific face exercises or something? I'm tired of being so baby faced. And please don't tell me I'll be thankful for it when I'm older...I want to find a way to make my face and neck look more toned.
