What it is
Kybella is synthetic deoxycholic acid — the same molecule the body uses to break down dietary fat. Injected into the submental fat compartment, it disrupts the fat cell membranes; the contents are cleared over weeks. The destroyed fat cells do not return.
How we approach it
Kybella suits a specific patient: modest to moderate submental fullness, reasonable skin elasticity, and willingness to commit to a series.
The first visit includes a candid evaluation: is the chin profile a fat problem or a skin problem? Patients with significant laxity often look worse, not better, after fat loss alone. For those patients, we recommend assessing skin tightening (radiofrequency or ultrasound) first or in combination.
When Kybella is the right call, treatment is mapped — a grid of injections placed at safe-zone intervals — and dose is calibrated to the area and the session number.
What to expect
Swelling is the defining post-treatment experience. The neck and chin will be noticeably swollen for two to seven days; firmness and soreness may persist a week or two. Most patients plan around this. A “look thicker before thinner” phase is normal.
Most candidates require two to three sessions spaced four to six weeks apart. Final result is judged at one to three months after the last session.
Candidacy
Good candidates have submental fullness as the primary complaint, with adequate skin tone to retract after fat loss. Poor candidates have significant skin laxity, active infection in the treatment area, or are pregnant or nursing. If Kybella is not the right call, the clinician will recommend the alternative — typically tightening, sometimes nothing at all.
