Buccal Fat Removal at 40? (photo)

I am 40 years old but even now, my cheeks look fuller than in past years. I thought on a buccal fat removal but wonder if such work would make my cheeks look saggy. I am not fat and even in a normal weight, my face looks round. Is there another alternative to this procedure? I would not like to employ fillers as I had a very bad experience with them in the past. The great advantage of my face shape is a young look. Would I look my age if I got a bichectomy? Thanks in advance
