Submental Liposuction

What is Submental Liposuction?

Submental liposuction is a minimally invasive surgical procedure that removes excess fat from beneath the chin, jawline, and upper neck—the submental region. A small tube called a cannula is inserted through tiny incisions beneath the chin and behind the ears, and gentle suction is used to remove targeted amounts of fat from each area, sculpting a smoother, more defined jawline and neck profile.

It is one of the most effective treatments for submental fat—often called a "double chin"—that is resistant to diet and exercise. Because fat cells are permanently removed, results are long-lasting with weight maintenance.

What It Can Address

• Stubborn fat beneath the chin ("double chin")
• Fullness in the upper neck that softens the jawline definition
• A blunted or poorly defined cervicomental angle (the angle between jaw and neck)
• Disproportionate fullness under the chin relative to body weight
• Genetics-driven submental fat that is unresponsive to lifestyle changes

The Procedure

The procedure is performed under local anesthesia with sedation and typically takes under an hour. Dr. Kieu makes one to two tiny incisions beneath the chin—each just a few millimeters—and uses precise cannula movements to remove fat from the targeted areas. The incisions are so small they are nearly invisible after healing.

A compression garment is worn under the chin following the procedure to support healing and help the skin conform to its new contour.

Recovery

Most patients return to work and normal activities within 5–7 days. Swelling, bruising, and some tightness beneath the chin are typical in the first week and gradually resolve. The compression garment is worn for about one week. Final results—including full skin retraction—are usually visible within 2–3 months.

Ideal Candidates

• Patients with submental fat that is resistant to diet and exercise
• Those with good skin elasticity (the skin needs to contract after fat removal)
• Adults at or near a stable, healthy body weight
• Patients who want jawline definition without more extensive surgery
• Good general health and realistic expectations

How It Compares to Non-Surgical Options

Non-surgical fat reduction treatments like Kybella can also address submental fat, but require multiple sessions and produce more gradual results. Submental liposuction provides immediate, more significant, and permanent fat reduction in a single procedure. Dr. Kieu will discuss the best option for your anatomy and goals during your consultation.

Often Combined With

Dr. Kieu's Approach

Dr. Kieu uses a precise, graduated approach to submental liposuction—removing fat strategically to achieve a smooth, natural contour rather than an over-suctioned result. She evaluates the relationship between the chin, jaw, and neck to determine how much fat removal will create the most harmonious profile for each individual patient.
