I'm 24 years old, slim, and I cannot get rid of my chubby cheeks with diet and exercise. My mother still has chubby cheeks in her 50s so I do not expect they will fine down with age. At rest I feel they have a somewhat saggy appearance. This does bother me somewhat, but not so much as the projection (to the front and sides) when I smile. I've attached photos of my smile and my face at rest.
