Injection lipolysis chemically reduces the number of fat cells around the injection site. The chemical, called deoxycholic acid, results in fat cell disruption and death. Currently, it is FDA-approved for treatment of the area underneath the chin to eliminate what is known as a "double chin."
Nonsurgical candidates and patients interested in a nonsurgical approach to reducing the fat beneath the chin may be interested in injection lipolysis.
There is no downtime, but patients may experience swelling, bruising, pain, redness and feel areas of hardness that typically soften with time. Fat reduction is typically visible by eight weeks.
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. 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.
