How Does Kybella, The Fat-Dissolving Injection, Work?

Updated: Jan 20, 2023

Are you bothered by your double chin? Well, you are not alone. Some people are genetically inclined to acquire submental fat. In contrast, others develop a double chin due to age and weight increase. Submental fullness, sometimes known as a “double chin,” is the extra fat that builds up behind the chin.

An injectable procedure called Kybella targets fat deposits under the chin. In this treatment, the doctor will inject deoxycholic acid to dissolve the fat cells in this area. Through a series of injections, the FDA-approved technique Kybella progressively eliminates the fat cells beneath your chin.

The results Kybella produces are long-lasting, it is a safe procedure, the procedure itself is simple, and there is no extended recovery time. Although Kybella is quickly gaining popularity, many people still need clarification about what it is, how it works, and why they should use it. These questions will be addressed, so stick around!


The nonsurgical injectable procedure Kybella treats the fat under the chin. The process uses a series of deoxycholic acid injections to target the fat cells in this location. The downtime is often brief, and there are no incisions necessary.

Adults 18 years or older with moderate to severe submental fat are the most outstanding candidates. If you have had or intend to have face surgery, have difficulties swallowing, are pregnant or nursing, have an illness or medical condition at the planned injection location or are pregnant or nursing, you may not be a good candidate.

According to a 2015 consumer study by the American Society for Dermatologic Surgery (ASDS), 67 percent of people are concerned by extra fat in their necks or beneath their chin. The only injectable now FDA-approved to address the appearance of a double chin is Kybella.


It’s crucial to discuss your Kybella treatment plan with your provider and confirm that you are a good candidate for the treatment. Talk about your medical history and any face, neck, or chin cosmetic surgery you’ve received. Any difficulty swallowing or bleeding issues should be disclosed to your healthcare practitioner.

Inform your healthcare practitioner if you are nursing a baby, pregnant, planning a pregnancy soon, or already nursing. Research on Kybella’s impact on a fetus or newborn is still in progress.


The practitioner will first mark 20 to 50 injection sites under the chin with a marker to reduce pain or discomfort. It is followed by using a topical anesthetic or an ice pack. The treatment will next focus on the fat cells using a synthetic version of deoxycholic acid administered by a qualified medical specialist at Prim Rose Reno.

Deoxycholic acid aids the body’s normal fat absorption, as suggested. This acid, a salt in human bile, helps the body better digest fat by rupturing the fat cell membrane inside the digestive system. The lymphatic and circulatory systems then break down and eliminate the extra fat after it has been dissolved.

Additionally, the acid will dissolve the fat cells under the chin after being injected. The body begins to break down the fat cells weeks after the therapy. In other words, the acid also signals the region that it can no longer retain fat.

Only obtain the Kybella procedure from a qualified medical practitioner since improper administration of the deoxycholic acid during the process might result in the death of other cells. Additionally, some individuals may experience discomfort with Kybella injections. Suppose you are worried about your pain tolerance. In that case, you should talk to your provider beforehand so that a topical anesthetic cream like lidocaine can reduce discomfort.

Each patient requires a different amount of sessions. To achieve the best outcomes, many treatments could be necessary. Up to six Kybella treatments are permitted, with a minimum of one month between each one.


Kybella destroys the fat cells in the treatment region as it activates. Once the cells are eliminated, they won’t reappear. Deoxycholic acid is a synthetic compound made safely in a lab environment and is utilized in Kybella. The acid dissolves the cell membrane and kills the fat cells when injected into the treatment region. These cells are subsequently metabolized by the body and eliminated by standard processes.

Comparing Kybella to other fat-removing treatments, there are some advantages. Here are some of them:

  • Kybella is a nonsurgical treatment option. It implies that there is no recovery time needed following your procedure. After the treatment, you can return to your regular activities immediately.

  • Since the 1990s, Kybella has been utilized in Europe and is supported by many studies. In 2015, the FDA gave Kybella its OK for usage in the US. Kybella is safe and effective, with few adverse effects, according to clinical investigations.

  • The Kybella procedure is simple and quick. For your treatment, plan on being in the office for around 45 minutes. You won’t need much downtime, so you may get on with your regular activities immediately after the treatment.

  • The effects of Kybella therapy are long-lasting. Once the fat cells are gone, they won’t come back.


A treatment plan should be created by your practitioner, considering your requirements. Most people need more than one Kybella treatment to achieve their desired cosmetic results. In clinical tests, many patients who got the Kybella treatment saw improvements after two to four sessions.

A Kybella treatment typically lasts for 20 minutes, during which a professional may provide up to 50 injections of the substance using the same syringe. Typically, the injections are spaced approximately a centimeter apart. The typical adverse reactions following a Kybella injection are:

  • Bruising

  • Swelling

  • Inflammation

  • Pain

  • Redness

  • a brief numbness at the injection site

Additional negative consequences include:

  • Having trouble swallowing ( dysphagia)

  • a skin ulcer

  • a brief nerve injury

  • loss of beard hair, whether temporary or permanent

Usually, the swelling subsides within a few days to a few weeks.

After the treatment, patients may typically resume their daily routine. Professionals may suggest a compression garment to reduce inflammation.


Submental fullness is a condition that affects a lot of people. Approximately one-fourth of the fat in your submental area can be removed immediately with Kybella injections.
