There are a few options to contour and reshape the neck, but they are limited by the structural problem encountered, such as the amount of fat, quality of the skin and laxity of the underlying muscles.
Very loose skin and underlying muscles of the neck will necessitate tightening of these loose tissues with a Facelift. This procedure will also smooth the jaw line and improve the cheek region, yielding a very natural and rejuvenated appearance.
However, if the issue is accumulation of fat under the chin and jawline then there are other suitable options.
Kybella is an injectable, which assists in dissolving fat deposits. It requires multiple injections, is not very precise, will not tighten the skin and is best for small localized fat deposits.
On the other hand, Liposuction of the jawline and neck is a contouring procedure that utilizes thin cannulas or rods inserted through small incisions, which are placed within creases to camouflage the incisions, through which fat is suctioned. In the process, the overlying skin is shifted or re-draped allowing the skin to adjust to the new underlying contour.
What are the differences? Liposuction is a one-time deal vs. multiple sessions with the injectable. Liposuction offers greater precision in removing unwanted fat, with minimal discomfort, however; unlike the injectable, it is an outpatient procedure, so you will need to take some time off for minor swelling and bruising to subside.
So who should have which procedure?
Kybella is best for individuals with tight neck skin and small pockets of fat below the chin.
Liposuction of the neck and chin is the best option for contouring option the area below the jaw and under the chin. I recommend a Facelift for those who wish a true rejuvenation of the neck, jaw and face,, which is truly an uplifting experience.
