Does Lipo of Chin/jowls Make the Face Look Thinner?

Facial sculpting and contouring can be created with well-placed fillers (Voluma, Countour, Radiesse, Bellafill) and Sculptra, which would give improvement in facial balance. Fat or implants are alternatives. I recommend getting a formal evaluation with a facial sculpting expert. Best, Dr. Emer

Liposuction of the chin and jowl area will mainly help improve the appearance of your profile. It will not do much for the head on view. General weight loss and possibly buccal fat removal (depending on your needs) will help your face appear thinner. Photos would really be necessary to provide you with additional advice. If your cheeks appear to be fatter than your jaw line, then buccal fat removal may be an option. Thank you, and please feel free to ask any additional questions, I would be happy to answer them for you!

We never recommend liposuction in the face.  Fat atrophy is a part of the normal aging process and fat removal from anywhere in the face will accelerate that. 
There are 2 compartments of fat in the neck and are referred to as submental and subplatysmal fat.  The best alternative to simple liposuction is called a neck lift, it involves removing fat from both compartments in the neck.   A platysma-plasty is also performed because improvement to the jawline and neck as well.  Traditional liposuction in the neck will not remove the subplatysmal fat and can leave residual fullness in the neck if it is not addressed. 

We never recommend liposuction of the jowls.  A lower facelift is required to re-suspend and adequately address jowls.  There are salivary glands in the face and neck that are not removed and must be left alone.   They would not be addressed with any fat removal of the face or neck.  It is best to have a consultation by a board certified facial plastic surgeon to get more information.
