kybella

That stubborn pocket of fullness under the chin—often called a “double chin”—can be surprisingly resistant to diet and exercise. Kybella is an FDA-approved injectable that permanently dissolves that fat, no surgery or downtime required. If you’ve been researching how it works, how many treatments you’ll need, and what Kybella cost looks like, this guide walks you through all of it.

What Is Kybella?

Kybella is an injectable treatment made from deoxycholic acid, a molecule your body naturally uses to break down and absorb dietary fat. When injected into the fat beneath the chin—the submental area—it destroys those fat cells for good. Once they’re gone, they can’t store fat again, which is what makes results permanent.

It’s the only injectable of its kind approved specifically to treat a double chin, offering a non-surgical alternative to liposuction. If you’d like to explore other fat-dissolving options, our post on liquid lipo injections is a helpful companion read.

How Does Kybella Work?

During treatment, your provider marks a grid over the under-chin area and administers a series of small injections. The deoxycholic acid disrupts the walls of the fat cells, which your body then clears away naturally over the following weeks. As the fat is eliminated, the area under the chin becomes slimmer and the jawline looks more defined.

Because your body needs time to process and remove the destroyed fat cells, results appear gradually rather than overnight—a natural-looking transition that others often notice without knowing exactly what changed.

Who Is a Good Candidate?

The best way to know for sure is a consultation, where your provider assesses your anatomy and skin quality and confirms Kybella is the right tool for your goals.

How Many Sessions Will You Need?

Most people need two to four sessions spaced about a month apart, though some want more depending on the amount of fat and their goals. Because the results are permanent, this is a build-toward-your-goal treatment rather than something you repeat forever. Once you’ve reached the look you want, no maintenance sessions are typically needed—a key advantage over treatments that fade.

How Much Does Kybella Cost?

Kybella cost depends on a few factors, so pricing is best confirmed at a consultation. The main variables are:

Because Kybella permanently removes fat cells, many patients view it as a one-time investment rather than an ongoing expense. We’ll give you a clear, personalized quote at your consultation so there are no surprises.

What to Expect After Treatment

Swelling under the chin is the most common and expected after-effect—in fact, it’s a sign the treatment is working. Some people also notice tenderness, numbness, or firmness in the area for a few days to a couple of weeks.

Kybella vs. Other Double Chin Treatments

Kybella isn’t the only way to address submental fullness, so it helps to see how it fits alongside the alternatives. Liposuction removes fat surgically in a single procedure, but it involves anesthesia, incisions, and real downtime. Fat-freezing devices offer a no-needle option, though they can require bulky applicators and multiple cycles. Kybella sits in a sweet spot for many people: it permanently dissolves fat with quick injections and no surgery, and it can reach smaller, more precise pockets that other methods struggle with.

The best choice depends on how much fat you have, your skin quality, and your goals—which is exactly what a consultation is designed to sort out.

Frequently Asked Questions

Are Kybella results permanent?

Yes. Once the fat cells are destroyed and cleared by your body, they can’t return. As long as your weight stays stable, results are long-lasting.

Does Kybella hurt?

You’ll feel some stinging or warmth during the injections, and the area is often numbed beforehand for comfort. Most people tolerate it well and return to normal activities the same day.

How long is the swelling after Kybella?

Swelling is usually most noticeable in the first few days and settles over one to two weeks. It’s part of the process as your body responds to the treatment.

Is Kybella cheaper than liposuction?

Kybella cost is generally lower than surgical liposuction and involves no anesthesia or downtime, though the right choice depends on your goals. A consultation will help you compare.
