My face is really fat and chubby how can I stop being chubby?

My body and legs are REALLY skinny I have fast metabolism it's just that my fat goes to my face. Also I am still growing so I don't want to not eat or eat less because I eat in moderation and I don't eat fatty foods. Anything I can do to loose the fat of my face (it's more likely to be baby fat) but seriously it makes me look chubby. A lot of people has said I look chubby but I am under weight. Just my face is fat!!!!
