I am unsatisfied with the shape of my face. I feel it is too thin. I was wondering if...
Yes, fat injections can be used to plump up a thin face. There are also facial implants available for augmenting the cheeks, the chin, the area below the cheeks, the temple area, and the side of the jaw bone or mandible. A qualified plastic surgeon can examine your face and determine which would be best for you. Your under-bite may be corrected at the same time but the type of correction also depends on the extent of your "under-bite." Again I suggest that you consult with a board-certified plastic surgeon.
