Age 43, looking for suggestions to correct facial structure deficiencies? (Photo)

Based on the side profile, I do think that you could benefit from cheek and chin implants. If you are hesitant to jump into that, you could consider fillers to the region to give you an idea of the change and see if this change is the long-term solution you seek.

A full set of facial photographs from all angles are going to be required to make a determination about how best to proceed. From this one limited photograph, it appears that you have a mild recessive chin, so consider placement of a small chin implant to augment your chin forward for better facial balance and proportions. This procedure can be performed under local anesthesia as an outpatient procedure.
