How to lose face fat?

I’m 19 going on 20 and I still have chubby cheeks like a child! People always think I’m 13/14 and when I tell them I’m junior in college they laugh like it’s a joke. I believe my round face makes me a lot younger than I want it to. The thing is that I’m a little less than 100 pounds (5’3) so I don’t want to really lose any body weight. Is there anyway to lose only face fat and if so, how?
