What Is Double Chin Liposuction?
It is a procedure in which excess submental fat is removed with fine cannulas to define the jaw–neck line. It provides a sharper jaw profile and a more youthful neck appearance.
In which cases is it preferred?
- Reducing the appearance of a “double chin” caused by weight or genetics
- Adding definition to the neck and jaw area
- Reducing the signs of age-related sagging
Procedure and recovery
It is usually performed in approximately 30 minutes under local anaesthesia, with sedation if needed. Patients are discharged and may return to daily life the same day. A chin compression garment is used for the period advised by the surgeon; the final result is seen in 3–6 months.
Who is it suitable for, and who is it not?
Two things determine the result of submental liposuction: the fullness under the chin really being fat, and the skin having enough elasticity to redrape.
- Suitable: people with good skin elasticity whose fullness under the chin comes from fat.
- Not suitable: those whose excess comes from skin laxity or platysmal banding. In that picture removing the fat exposes the laxity; a neck lift is the better answer.
- A receding chin (retrognathia) can mimic the appearance of a double chin; in that case removing fat will not give the expected profile.
This distinction is made at the examination and directly determines whether the procedure succeeds.
Risks you should know about
A systematic review published in the Journal of Oral and Maxillofacial Surgery in 2026 examined 2,085 cases from 13 studies of aesthetic submental liposuction. A total of 270 adverse events were reported, giving a rate of 12.9% per procedure. Of these, 74.8% were minor in nature and could be managed on an outpatient basis.
The commonest were fluid collection (21.1%), surface irregularity or asymmetry of the skin (19.1%) and platysmal banding (18.5%). The mean time to onset was 1.7 months — that is, problems usually appear in the first months rather than late.
The practical conclusion is this: submental liposuction is a small procedure, but not one without consequences. Because the region is delicate, the chance of surface irregularity is more noticeable here than in areas of the body.
When does the result become clear?
In the first days swelling can make the area look fuller than it did before the procedure; this is an expected course. The chin strap is worn for the period your doctor specifies, so that the swelling settles and the skin adapts to the new contour. The lines become clear over 3–6 months; judging the result from the early appearance is misleading.
It is not suitable if the fullness under the chin comes from skin laxity or platysmal banding rather than fat; in that picture removing the fat exposes the laxity and a neck lift is the better answer. A receding chin can also mimic the appearance of a double chin.
It is usually performed under local anaesthesia, with sedation if needed, in about 30 minutes. Same-day discharge and a return to daily life are possible.

The cannulae enter through incisions of one to two millimetres under the chin; the entry points are hidden in the submental crease and behind the ear, and become indistinct over time.
The fat cells that are removed do not come back; but if weight is gained the remaining cells can enlarge and the fullness can partly return. What preserves the result is a stable weight.
