A double chin is one of the few things diet and exercise often can't touch — the fat under the chin tends to stay long after the rest has gone. Kybella is the injectable that addresses it directly, and at Privé Aesthetics in Dallas, it's the tool we reach for when the goal is a cleaner jawline without surgery.
The area under the chin — the submental region — is stubborn by design. For a lot of people it's genetic, holds fat independently of overall weight, and doesn't respond to the gym. Kybella is the only FDA-approved injectable built specifically to dissolve it. Here's how it actually works, who it's for, and what the process looks like.
What Kybella actually is
Kybella is deoxycholic acid — a molecule your body already makes to break down dietary fat. In a controlled, purified, injectable form, it's placed in a precise grid of small injections into the fat beneath the chin. There, it does exactly what it does in digestion: it breaks down fat cells. The difference is permanence — once those fat cells are destroyed, they're gone, and they can't store fat again.
The part that makes it worth it: it's permanent
Most non-surgical fat treatments reduce the size of fat cells; Kybella eliminates them. Practically, that means once you've completed your series and the swelling resolves, the result is durable — the treated cells aren't coming back. Future weight gain can still add volume elsewhere, but the submental pocket you treated won't rebuild the way it was. That's the trade you're making: a few weeks of swelling now for a structural change that holds.
Who Kybella is right for — and who it isn't
It's an excellent fit for someone with moderate submental fullness — a defined "double chin" or softness under the jaw — and reasonably good skin elasticity, so the skin retracts cleanly as the fat reduces. It is not a weight-loss tool, and it isn't the answer for loose or sagging skin (that's a skin-tightening or surgical conversation, not a fat one). At consultation we look honestly at whether your concern is fat, skin, or bone structure — because Kybella only solves the first.
The timeline — and the swelling nobody warns you about
Kybella is done as a series of two to four treatments, spaced about six weeks apart, depending on how much submental fat you're treating. The honest part: there is real, visible swelling for the first few days after each session — sometimes significant (patients sometimes call it the "bullfrog" stage). It's expected, it's temporary, and it's the sign the product is working. Most people plan a few low-profile days around it. The fat reduction itself reveals gradually over the weeks between sessions.
Kybella vs. CoolSculpting
We're often asked why we use Kybella instead of CoolSculpting for the chin. Both reduce fat permanently, but they work differently: CoolSculpting freezes fat through an applicator, while Kybella is injected with precision into a small, contoured area. For the submental region specifically — small, curved, close to important anatomy — we find the injectable's precision better suited than an applicator. It's also why Kybella is the tool we offer here, and CoolSculpting is one we deliberately don't.
What it costs, plainly
Kybella at Privé is $600 per vial, with most plans using a series of two to four treatments depending on the amount of submental fat. We map the likely number of vials and sessions at consultation so the full investment is clear before you start — no per-session surprises.
How it fits the bigger plan
A sharper jawline is rarely about one thing. Kybella removes what softens the jaw; jawline filler can add definition along the mandibular border, and Sculptra rebuilds the deeper structural support that age thins out. For the right patient we sequence these — reduce, then define, then support — rather than asking any one of them to do the whole job.
Frequently asked
How much does Kybella cost in Dallas at Privé?
Kybella is $600 per vial, with most plans using a series of two to four treatments depending on how much submental fat is being treated. We map the likely number of vials and sessions at consultation so the full investment is clear up front.
Is Kybella permanent?
Yes. Kybella destroys the fat cells it treats, and destroyed fat cells don't return or store fat again. Once your series is complete and swelling resolves, the result is durable — though significant future weight gain can still add volume elsewhere.
How many Kybella treatments will I need?
Most patients need two to four treatments spaced about six weeks apart. The exact number depends on the amount of submental fat and your goal, which we assess at consultation.
Does Kybella hurt, and what's the downtime?
We numb the area first, so the injections are tolerable. The notable part is swelling — expect real, visible swelling under the chin for the first few days after each session (sometimes significant). It's expected and temporary; most patients plan a few low-profile days around each treatment.
Am I a good candidate for Kybella?
It's best for moderate submental fullness (a 'double chin') with reasonably good skin elasticity. It's not a weight-loss treatment, and it's not the right tool for loose or sagging skin. We confirm at consultation whether your concern is fat, skin, or structure — Kybella only addresses fat.
How is Kybella different from CoolSculpting?
Both permanently reduce fat, but Kybella is injected with precision into a small, curved area while CoolSculpting freezes fat through an applicator. For the submental region specifically, we prefer the injectable's precision — which is why we offer Kybella and don't offer CoolSculpting.
