28 - How can I get rid of my round cheeks? (Photos)

I am 28 years old and for as long as I can remember, I have always had a wide smile that cause my cheeks to go beyond my jawline and even make my eyes appear half open when I smile. I work out 3-4 days a week and have a healthy diet (I even have a slightly visible 6 pack) but for some reason and I can’t seem to lose weight in my face or have it have a slimmer appearance. When I am not smiling or talking, my appearance is fine but when i avoid smiling due to it feeling unflattering. What procedure can assist me with trimming down my face and achieving a more chiseled appearance?
