Buccal fat pad reduction can be an option to consider in carefully selected patients with prominent lower cheek fullness, or what some refer to as "chipmunk cheeks." It is difficult to be certain from your photo, but it does not look like you would be the ideal candidate for this procedure. In a young patient such as yourself, removing buccal fat can cause you to look prematurely aged as you get older and the remaining facial fat that you have shrinks and descends, as it does for everyone as the natural aging process progresses. Liposuction can be a great procedure to remove fat from the jowls and under the chin, but again this is likely not the procedure that would give you the facial definition and inverted triangle appearance that many find desirable. Instead, I would consider augmentation of the upper cheeks with fillers or implants, and possibly Botox to the masseter muscles that overlie the jaw in order to slim the lower portion of the face without permanently removing fat from an area that is essentially impossible to replace. Best wishes,
