Most patients require two to four treatments spaced about one month apart, though some need up to six based on submental fullness. Dr. Javaheri evaluates anatomy and goals to recommend an individualized treatment plan during a consultation.

Most patients feel a brief stinging during injection; topical numbing and local anesthesia are used to improve comfort. Post-treatment swelling or tenderness can last several days but is generally manageable with cold compresses and over-the-counter pain relievers.

Common side effects include temporary swelling, bruising, numbness, redness, and firmness at injection sites, typically resolving within days to weeks. Rare complications can include prolonged paresthesia or marginal mandibular nerve weakness; Dr. Javaheri discusses risks and mitigation strategies during evaluation.

Results appear gradually as treated fat is absorbed; measurable improvement is often visible within four to six weeks, with continued refinement over several months. Final contour is typically apparent after the full series of treatments and is considered long-lasting.

Kybella is ideal for reducing mild-to-moderate submental fat but does not address significant skin laxity or muscle banding. Patients with severe excess or loose skin may achieve better, more predictable results with surgical neck lift or liposuction; Dr. Javaheri recommends tailored options.

Kybella destroys treated fat cells, offering permanent reduction in that area. However, remaining fat cells can enlarge with weight gain, potentially altering appearance. Maintaining stable weight and following postoperative guidance helps preserve long-term contour achieved by the treatment.
