How Long Does Kybella® Swelling Last?

In the past, you had limited options for getting rid of a double chin. Procedures like liposuction can remove excess fat, but today you have a less invasive option. Kybella® removes your double chin with a series of injections.

What is Kybella®?

Kybella® is a minimally invasive injectable that gets rid of submental fullness (fat under the chin). The FDA has approved Kybella® as the first injectable for this purpose. By breaking up fat cells, Kybella® gives you a more sculpted profile and a slimmer neck.

How Does Kybella® Work?

To break up fat cells, Kybella® used a synthetic deoxycholic acid. The natural version of this molecule occurs in the digestive system, where it helps the body process dietary fats. When injected into the layers of fat under the chin, Kybella® causes fat cells to break down. The body will filter away these damaged cells to leave the area more slender and shapely.

How Long Does Kybella® Swelling Last?

Swelling is the most common part of the healing process and a normal sign that your body is responding to treatment. Double chin injection swelling typically peaks within the first few days after your session and gradually improves over time. On average, the Kybella recovery time for swelling is about two to three weeks. Treatments are spaced about four weeks apart to allow all swelling to resolve before your next session.

You might also experience mild bruising, numbness, or tenderness — common indicators of your body’s natural healing. The Kybella side effects duration for these symptoms is usually just a few days, but can occasionally last up to a week. Most patients feel well enough to return to work or daily activities immediately after their appointment.

Kybella® Aftercare Tips

While the body handles most of the healing process on its own, following a few Kybella aftercare tips can make recovery more comfortable and may even help speed things up:

1. Apply a cold compress for short intervals during the first 24 hours to help reduce Kybella swelling.
2. Sleep with your head elevated for the first few nights to minimize fluid accumulation.
3. Avoid strenuous exercise, saunas, or hot tubs for 48 hours, as heat can worsen swelling.
4. Stay hydrated and eat a balanced diet to support your body’s natural elimination process.
5. These simple steps can help you feel more comfortable during recovery and support optimal results.

Am I a Good Candidate for Kybella®?

Most people make good candidates for Kybella®. You should let your Rejuve Med-Spa RN know about any health problems. If you have an infection in the area, you may need to wait for this to resolve before getting your next treatment. 

What Results Will I See With Kybella®?

Most people will start to see results with Kybella® after two to four treatments. You may see results begin to develop after four to six weeks, but you will not see your full results until after all your treatments. Results continue to develop as the body gradually filters away the damaged fat cells.

After the body has removed submental fat, it does not grow back. Your double chin removal will last as long as you maintain a consistently healthy lifestyle. You should not need any more treatments after your initial series.

What are the Benefits of Kybella®?

Choosing Kybella® means investing in a safe, effective, and convenient solution to sculpt your jawline and redefine your profile. All of these effects come without the need for surgery or lengthy recovery. Here’s why patients love this innovative treatment:

1. Quick Results With Minimal Downtime

One of the biggest advantages of Kybella® is its short Kybella recovery time. Most people return to their normal routines immediately after treatment, with only mild swelling or tenderness that resolves within a few weeks. Because there’s no surgery and no lengthy healing period, you can enjoy a more contoured look without putting your life on pause.

2. Non-Surgical and Minimally Invasive

Kybella® is a breakthrough alternative to invasive procedures like liposuction. With just a series of injections, you can target stubborn submental fat and achieve a smoother, more defined jawline. This means no incisions, no anesthesia, and no scars — just natural-looking results with a straightforward treatment and predictable Kybella side effects duration.

3. Effective Reduction of Double Chin Fat

If you’ve struggled with stubborn fat under the chin despite diet and exercise, Kybella® can help. By breaking down and permanently removing fat cells, it offers dramatic improvement in double chin injection swelling and overall fullness, leaving you with a slimmer, more youthful profile.

4. Long-Lasting, Natural-Looking Results

Once Kybella® destroys fat cells, they don’t come back. That means your results can last for years, as long as you maintain a stable weight and a healthy lifestyle. With proper Kybella aftercare tips, you’ll enjoy a refined neckline and a confidence boost that looks completely natural.

5. Personalized Treatments and Gradual Enhancement

Every patient’s treatment plan is tailored to their specific needs, allowing for a gradual transformation over time. As swelling subsides and fat cells are metabolized, you’ll notice continued improvement in your contour. And if you’re wondering how long Kybella swelling lasts after injection, most patients see steady progress within 2–3 weeks, with optimal results after completing their full treatment series.

6. Easy Maintenance and Confidence-Boosting Results

Because Kybella® results are permanent, you won’t need frequent follow-up treatments. A few simple steps are usually all that’s needed to support your body’s natural healing and enjoy your new look for the long term.
