My cheeks are droopy and my smile lines are very deep. What should I have done? (Photo)

Patients with chubby cheeks (fulness of the anterior lower cheeks) could benefit from buccal fat removal. 
Buccal fat removal is the plastic surgery procedure that removes the excess of fat of the lower cheeks to achieve non-chubby, think V shape face. The video bellow helps to understand who could be a candidate for buccal fat removal. 
Droopiness of the cheeks would be also secondary to weak cheek bones. Therefore Enhancing the cheek bones with fillers would help to achieve a non-droopy facial appearance. 

Based on your photographs, I think you would be an excellent candidate for buccal fat excision.  Buccal fat excision is a fairly quick procedure.  To allow time for preparation and anesthesia, the whole procedure takes approximately one hour.
The recovery time after buccal fat excision is rather quick. After the procedure, you will have a few stitches from the small incisions made on the inside of the mouth.  You will need to eat a soft diet for 3 to 4 days. There will be some swelling present in the face after the surgery. The swelling is typically moderate and will slowly resolve over a few weeks.
I hope this helps!
