Most patients have at least two treatments spaced 4 to 6 weeks apart, which is the typical duration of swelling. Patients can have up to six treatments to the area under the chin. Your plastic surgeon can develop a plan that best suits your individual anatomy. During the period of swelling the area can look fuller than it did before treatment, but as the fat cells are disrupted and the inflammation subsides, most patients see results by 6 to 8 weeks after a treatment. Unless a patient were to gain weight, the results should be long-lasting
