Many people of all ages struggle with excess fat beneath the chin, in what is referred to as the “submental triangle” area of the face. Fullness in this area is sometimes accompanied by sagging skin in people who are a bit older, but for many people, the extent of the issue is unwanted stubborn fat under the chin.
People are often embarrassed by their “double chin” and are anxious to improve the appearance of the area. Unfortunately, the submental triangle does not generally respond well to diet and exercise, leaving some frustrated by their efforts. The good news is that a few treatment options are available for contouring the area under the chin, including Kybella treatments and submental liposuction. But what is the difference between the two procedures, and why do the differences matter?

Chin Liposuction vs Kybella in a Nutshell
Submental liposuction is a surgical procedure with immediate, dramatic results, requiring anesthesia and some recovery time, but it’s a one-time treatment with a higher upfront cost. Kybella is a non-surgical injectable option with minimal downtime, providing gradual results over multiple sessions, which may increase the overall cost. Both options effectively target submental fat, but the choice depends on your preferences for immediacy, invasiveness, and budget. Consulting a skilled plastic surgeon ensures the best treatment and outcomes for your unique needs.
Submental Liposuction vs Kybella
What is Submental Liposuction?
Submental liposuction is a surgical procedure designed to remove excess fat from beneath the chin, commonly referred to as a “double chin.” Unlike Kybella, which uses injections to break down fat gradually, submental liposuction involves the physical removal of fat through small incisions. During the procedure, a surgeon inserts a thin tube called a cannula to suction out fat, resulting in immediate contouring of the chin and neck area.
This method is particularly suitable for individuals with moderate to severe submental fat who desire faster and more dramatic results. Ideal candidates often have good skin elasticity to ensure the skin tightens naturally after fat removal. For those with significant skin laxity, additional procedures like a neck lift may be recommended to achieve optimal results. Submental liposuction is a one-time treatment, making it distinct from the multiple sessions often required with Kybella.
What is Kybella?
Kybella is an FDA-approved injectable treatment specifically designed to reduce fat beneath the chin. It utilizes deoxycholic acid, a naturally occurring substance in the body that helps break down and absorb dietary fat. Unlike submental liposuction, Kybella is non-surgical and gradually dissolves fat cells over a series of treatment sessions.
Kybella is best suited for individuals with mild to moderate submental fat who prefer a non-invasive option. It’s particularly appealing to those who wish to avoid surgery, anesthesia, or extended recovery time. However, patients need to commit to multiple sessions—typically three to six treatments spaced six weeks apart—to achieve noticeable results. Kybella’s gradual fat reduction can be advantageous for those seeking a more subtle transformation over time. It’s important for candidates to have good skin elasticity to avoid sagging skin post-treatment, as Kybella does not address skin laxity.
The Cost of Chin Liposuction
The cost of chin liposuction can vary widely depending on several factors. Key considerations include the surgeon’s expertise, the complexity of the procedure, and geographic location. Additional costs may include anesthesia fees, operating room charges, and pre-operative tests.
While chin liposuction typically requires a higher upfront investment compared to Kybella, it’s a one-time procedure, which can make it more cost-effective in the long run. Patients are encouraged to consult with their surgeon to receive a detailed cost breakdown and understand what is included in the quoted price.
The Cost of Kybella
Kybella’s cost depends largely on the number of treatments required to achieve desired results. Each session typically includes multiple injections and may vary based on the amount of fat being treated. While the cost per session may seem lower than surgery, patients often require three to six sessions, which can make the overall cost comparable to or higher than chin liposuction.
Factors like the expertise of the injector and the clinic’s location can also impact pricing. During the consultation, patients should discuss the anticipated number of treatments needed and any additional fees for follow-ups or touch-ups.

Submental Liposuction Recovery and Results
The recovery process for submental liposuction involves some downtime, typically lasting about one to two weeks. After the procedure, patients are required to wear a supportive chin strap for the first week to minimize swelling and aid in skin retraction. Some bruising, swelling, and mild discomfort are common but generally subside within a few days.
Patients should avoid strenuous activities for at least a week but can usually return to work after a few days, depending on individual comfort levels. Final results become apparent as swelling diminishes, typically within a few weeks, with full contouring visible after about three months. Submental liposuction offers immediate and long-lasting results, providing a significant improvement in the neck and chin profile after just one treatment.
The Kybella Recovery and Results
Kybella’s recovery process is less invasive but requires patience. After each treatment session, patients may experience swelling, bruising, and tenderness in the treated area for three to five days. These side effects are temporary and usually mild enough to allow patients to return to work or normal activities shortly after the procedure.
Because Kybella works by gradually breaking down fat cells, results are not immediate. Patients typically start noticing changes after the second session, with optimal results visible about six weeks after the final treatment. Depending on the amount of fat being addressed, this process can take several months. While the recovery time is shorter than liposuction, Kybella requires multiple sessions for comparable results, making it a better option for those seeking a non-surgical approach.
Potential Complications of Chin Liposuction
As with any surgical procedure, chin liposuction carries some risks. These include infection, uneven fat removal, temporary or permanent numbness, and scarring. Rarely, complications related to anesthesia may occur. Choosing a skilled and experienced surgeon can significantly minimize these risks and ensure a safe and successful outcome.
Potential Complications of Kybella
Kybella is a non-surgical procedure, but it still comes with potential risks. Common side effects include swelling, bruising, and mild pain at the injection site. In rare cases, Kybella can cause nerve injury, leading to temporary facial muscle weakness or an uneven smile. Ensuring the procedure is performed by a trained and qualified injector can reduce these risks and provide the best results.
Which Procedure is Right for You?
Submental liposuction is ideal for those seeking immediate and dramatic results through a one-time procedure and don’t mind spending a couple of weeks in recovery, while Kybella is better suited for people who prefer a non-surgical option with gradual changes that won’t impact their day-to-day life too much. In both cases, you should have good skin elasticity to achieve the best outcomes.
No matter which option—submental liposuction or Kybella—is the best fit for your needs, choosing a highly skilled plastic surgeon is the most critical step in achieving a slimmer, more contoured chin. An expert surgeon will guide you through the decision-making process, ensuring the chosen procedure aligns with your goals and delivers safe, satisfying results.
