Laser liposuction for chubby cheeks?

You mentioned you already had liposuction? If the areas you outlined were in fact treated already by liposuction, you may have enlarge chewing muscles (hypertrophic masseter muscles) to cause the size of your mid cheek (not the area you drew along the jaw).  This area can be treated by an expert in this condition with Botox, but the result is temporary and there are side effects and risks that you need to discuss with that doctor before you undergo the treatment.

Chubby cheeks are actually composed of two different fat issues, the upper submalar area where the buccal fat pad lives and the lower submalar area which is not a separate fat compartment but diffuse subcutaneous fat. A buccal lipectomy will help reduce the size of the area right under the cheek but will not change the fullness below that closer to the level of the mouth. These are perioral mounds which can be reduced by very small cannula liposuction done from inside the corners of the mouth. Both locations of fat removal are needed to get the best reduction of chubby cheeks.

Removing the buccal fat pads is one way to decrease fullness in the lower face.  In fact, I had it done myself several years ago.  My partners and I generally do it through a small incision inside of the mouth and then close that incision with just one or two stiches that disolve so there are no scars on the face.  These fat pads are in the vicinity of the ink marks on the photos, but not that large.
