How do I achieve the "Hollow Cheek" look? (photos)

Buccal fat excision is an appropriate surgical procedure for patients that of overly full and wide cheek areas. In common terms, it is good for patients who have chipmunk cheeks. In reviewing your pictures, is difficult to tell if you're a good candidate because your cheek area is slightly full but not overly full. Liposuction can further slim the face. You are a patient that would need an in person consultation for a complete evaluation and explanation of the positives and negatives of these procedures in your situation. I hope this helps.

Dear Iso,
your weight loss surely is a great success and inspiration to others around you. Indeed your cheeks do already look rather slim, so further hollowing might result in unnatural looks. 
However: More Hollowness can be achieved through buccal fat exzision or improvement of the cheekbones with filler materials. The procedure that I right for you can be discussed in a personal consultation with a certifies plastic surgeon in your area.
