Buccal Fat Removal a Good Option for Slimmer Face?

Buccal Fat removal is a good, actually an excellent plastic surgery procedure to slim the face. Chubby cheeks or fullness of the lower anterior cheeks is commonly caused by enlarged buccal fat pads. Buccal fat removal by removing the buccal fat pads permanently, makes the face less full, more thin and/or chiseled in patient candidates. The video below helps to understand who could be a candidate for buccal fat removal. 

From your picture, it appears buccal fat pad reduction could be an option for you. However, you should keep in mind that you are young and these fat pads, along with all of the other fat pads in the face, will atrophy and become smaller over time without intervention. For this reason I would recommend only conservative reduction in the size of the fat pads, and not complete removal. Other options, such as Botox to the masseter muscle, can provide slimming of the lower portion of the face without the need for permanent tissue removal. I would advise you to consult with a facial plastic surgeon for an in-person evaluation to assess your concerns and make recommendations on which procedure or procedures are likely to give you the best result.
Best wishes,

As with any surgical procedure a patient has to be a good candidate.  Buccal fat extraction should be avoided in cases where a patient does not have excess fullness in the cheek region as it will create and aged and gaunt appearance.   In patients that have excess fullness in the buccal region buccal fat surgery can create beautiful results.  I prefer to be conservative in the majority of cases.
