Submental liposuction removes the fat under the chin and in the neck to produce a sharper jawline and neckline. This procedure is best in patients who still have elastic skin and involves a small 1 cm incision under the chin. Patients who are older and/or have loose skin under their chin are not as good candidates for this procedure. Patients usually don’t need any pain pills, and often go back to work after just a couple days.
