How is chin lipolysis performed?
Submental lipolysis, commonly referred to as “chin fat reduction” or “double chin treatment,” is a non-surgical cosmetic procedure designed to reduce localized fat deposits beneath the chin. The most widely used and FDA-approved method is deoxycholic acid injection (e.g., Kybella® in the U.S., Belkyra® in Canada and Europe). Deoxycholic acid is a naturally occurring bile acid that disrupts adipocyte (fat cell) membranes, leading to permanent destruction of fat cells in the treated area. Treatment involves a series of precisely placed microinjections into the submental fat pad—typically 20–50 injections per session—administered after careful mapping of the treatment zone and application of topical or local anesthesia to ensure patient comfort.
Candidates must undergo a thorough clinical evaluation to confirm that the fullness is due to excess fat—not loose skin, muscle laxity, or platysmal banding—as these conditions may require alternative interventions such as surgical neck lift, radiofrequency tightening, or neuromodulator therapy. Ideal candidates are adults with moderate submental fat, stable weight, and realistic expectations. Contraindications include active infection at the injection site, pregnancy or lactation, bleeding disorders, or prior history of dysphagia or nerve injury in the region.
A typical treatment course consists of 2–4 sessions spaced at least one month apart. Patients commonly experience transient side effects including swelling, bruising, pain, numbness, and induration—most resolving within 1–3 weeks. Rare but serious risks include marginal mandibular nerve injury (causing temporary asymmetry in smile), tissue necrosis, or dysphagia. Therefore, treatment must be performed by a qualified, experienced clinician trained in facial anatomy and injectable techniques. Post-procedure care includes gentle cold compresses, avoidance of strenuous activity for 48 hours, and diligent sun protection if swelling or bruising is present.
It’s important to emphasize that submental lipolysis is not a weight-loss solution; rather, it is a contouring procedure targeting resistant fat. Long-term results are durable provided patients maintain a stable weight, as remaining adipocytes can still enlarge with significant weight gain. A comprehensive consultation—including photographic documentation, discussion of goals, and review of alternatives—is essential before initiating therapy.
