Is Kybella Permanent? What to Expect Before, During, and After

If you’re researching whether Kybella is permanent, the short answer is yes, but there’s nuance worth understanding before you book. Kybella is an FDA-approved injectable that destroys fat cells under your chin. Those specific cells do not grow back. But your body can still gain weight, and the cells that were not destroyed can still grow with you. This guide walks through what Kybella actually does, what to expect at each stage of treatment, and where to get it in Orange County. At Eye Candy Medspa and Lash Bar, we offer Kybella fat dissolving injections in Orange County at all three of our locations, Buena Park, Lakewood, and Newport Beach.

What Is Kybella and How Does It Work?

Kybella is an injectable treatment that permanently destroys fat cells under the chin. Its active ingredient is deoxycholic acid, a synthetic version of a molecule your body already makes to break down dietary fat. When injected into the small pocket of fat below your chin (called submental fat), it ruptures the fat cell membranes, and your body clears the destroyed cells out naturally over the following weeks.

Kybella was approved by the FDA in April 2015 (you can review the official FDA approval history for Kybella). It was the first and is still the only injectable approved specifically for the treatment of moderate to severe submental fullness. It’s a real medication with real clinical trial data behind it, not a gimmick.

Is Kybella Really Permanent?

Yes, Kybella results are permanent for the fat cells it destroys. Once those cells are gone, they do not regenerate. That’s the part most articles will tell you.

What they often skip is the caveat: you can still gain weight after Kybella. If you do, the fat cells in your chin area that were NOT treated can still expand and store new fat. So if you lose your double chin to Kybella and then gain 30 pounds, you may see some return of fullness in the area, just less than before. To keep your results sharp long-term, maintaining a stable weight matters.

Who Is Kybella a Good Candidate For?

Kybella is a good fit for adults with moderate to severe fat under the chin who want a non-surgical option. It is not a weight loss tool, and it is not meant for very small amounts of fat that diet and exercise can handle. The best candidates are people who:

• Have visible fullness or a “double chin” that bothers them
• Maintain a stable weight and have generally good skin elasticity
• Want to avoid liposuction or surgery
• Can commit to a series of treatments (not a one-and-done procedure)
• Are not pregnant or breastfeeding and do not have an active infection at the injection site

If you have very loose skin in addition to fat, Kybella may improve the fullness but not the skin laxity. In that case, we may recommend pairing it with a skin tightening treatment or discussing other options during your consultation.

What to Expect Before Your Kybella Appointment

Before your first Kybella session, you’ll come in for a consultation where we assess your chin area, talk through your goals, and confirm Kybella is the right fit. In the days leading up to treatment:

• Pause supplements that thin the blood (fish oil, vitamin E, garlic supplements, St. John’s Wort) for about a week before, with your provider’s okay
• Avoid alcohol for 24 to 48 hours before your appointment
• Eat a normal meal beforehand
• Arrive with clean, freshly washed skin
• Plan to have a quiet evening after treatment, since you will likely swell

Many people schedule their first appointment on a Thursday or Friday so that the worst of the swelling has gone down before they head back into a normal social or work week.

What Happens During the Kybella Treatment?

The Kybella treatment itself is quick. The full appointment takes 30 to 45 minutes. We start by cleaning the area and marking a grid of injection points on your chin. A topical numbing cream or ice is usually applied to keep you comfortable. Then we administer the series of small injections, sometimes as many as 20 to 50 small shots in a single session, depending on the size of the treatment area.

You’ll feel a stinging or burning sensation during and immediately after the injections. That sensation is normal and usually fades within 15 to 20 minutes. Most people describe the treatment as uncomfortable but manageable.

What to Expect After Kybella: Swelling, Bruising, and Recovery

The “after” part of Kybella is where people get the most surprised, so here’s the honest picture. The first 2 to 4 days are the rough part. Expect:

• Significant swelling in the treatment area, sometimes enough that your chin and jaw look more full or “puffy” than before treatment. This is your body responding to the destruction of fat cells, and it is expected.
• Bruising, redness, and tenderness for several days
• Numbness in the chin area that can last 2 to 4 weeks
• Hardness or knots under the skin in the treated area as your body breaks down the cells

Most of the noticeable swelling resolves within a week, though some mild swelling can linger longer. The numbness fades gradually over a few weeks. Plan your social calendar accordingly. This is why so many providers recommend doing Kybella before a long weekend.

How Many Kybella Sessions Will You Need?

Most people need 2 to 4 Kybella sessions to see their final result, with some needing up to 6. Sessions are spaced about one month apart to give your body time to clear the destroyed fat cells and to allow swelling to fully resolve between treatments.

You’ll typically start seeing real change after the second session, around weeks 4 to 6. The full result builds over several months as your body completes the process of clearing out the treated cells. We’ll evaluate your progress at each visit and adjust your plan based on how you respond.

Are There Side Effects to Know About?

The common side effects of Kybella (swelling, bruising, numbness, redness, hardness in the treated area) usually clear up within 1 to 2 weeks. Less common but more serious side effects include nerve injury that can cause an uneven smile, weakness in the facial muscles, or trouble swallowing. These risks are why injector skill matters so much for Kybella. Choosing an experienced provider who knows exactly where to inject (and where not to) is the most important safety factor.

At Eye Candy, your Kybella treatment is performed by trained providers who screen you for risks before treatment and adjust based on your anatomy. If anything feels off after your appointment, you can reach us directly.
