Kybella Injections

•Treats Stubborn Submental Fat
•Sharper Neck-to-Jaw Angle
•Non-Surgical, In-Office
•Series of Spaced Sessions

A pad of fat under the chin can hold its size through a steady weight and regular exercise, because how much sits there is largely inherited. Kybella (deoxycholic acid) is injected into that pad and breaks down the walls of the fat cells it reaches. The body clears them over the following weeks, and the fullness reduces across a series of sessions.

What Are Kybella Injections?

Kybella is deoxycholic acid in injectable form, manufactured to match a molecule the body already makes to absorb fat from food. It is FDA-approved for submental fat, meaning the fat that collects below the chin and in front of the neck. Each injection ruptures the membranes of the fat cells around it, and those cells can no longer store fat. The tissue swells while the released fat and cell debris are carried away, which takes weeks, and the contour under the chin flattens step by step. That clearance sets the pace, so treatment runs as a series of visits.

Kybella at Beauty and Fly

Catherine Curtin, MSN, FNP-C, injects Kybella at both offices, in Bronxville and in Bridgehampton. She examines the pad by hand and in profile to confirm that the fullness is fat, then places a conservative dose at the first session so the response can be measured before the next one is booked.

Who Kybella Suits, and Who Should Wait

Kybella suits an adult whose weight has held fairly steady and who has a small, pinchable pad of fat under the chin that has not changed with diet or exercise. The skin over it needs to spring back well when released, since reducing fat under loose skin leaves the area looking emptier.
The area treated is the pad of fat beneath the chin. Reducing it opens the angle between neck and jaw, and in some profiles the jaw edge sharpens too.
Kybella is postponed during pregnancy and breastfeeding, when there is an active infection in the area, or when swallowing is difficult. Fullness caused mainly by loose skin is a separate concern and is assessed first.

What Are the Benefits of Kybella?

Kybella reduces the fullness under the chin without surgery. The fat cells it breaks down do not come back, though the cells left behind can still enlarge if your weight climbs, so the result holds best at a steady weight. The change shows in profile first, where the neck-to-jaw angle becomes clearer as the series goes on. Sessions take place in the office, with topical numbing applied before the injections are placed. Swelling, firmness and bruising under the chin follow each session, so the dates are chosen with that in mind. Consultations are complimentary and there is no deposit.

Kybella Treatment Areas

What Kybella Treats

Double Chin (Submental Fullness)

The pad under the chin is the area Kybella is approved to treat. It reduces across a series of sessions, and the change shows in profile long before it shows in a straight-on mirror.

Treatments+

Kybella is placed through a mapped grid so the whole pad is reached evenly. The broken-down fat cells are cleared over the weeks between visits, and the angle under the jaw opens up gradually.

Causes+

Under-chin fullness is largely inherited. The pad sits there at a stable weight, which is why diet and exercise often make no visible difference to it.

From the first session to the profile you keep

Right After Each Session

Early phase · swelling

The visit is topical numbing, a marked grid, then small injections placed point by point. Afterward the pad under the chin turns firm and full, and it swells visibly. The swelling is deoxycholic acid acting on the fat cells, and the visible part usually lasts longer than the tenderness.

Between Sessions

Mid-series · the pad flattens

In the weeks after a session, more of the treated fat has been cleared. The pad flattens, and the angle between the neck and the jaw starts to show from the side. This is usually the point where people notice the profile has changed.

Final Result (Later Sessions)

Final · refined profile

Once the swelling from the last session has gone down, final photographs are taken and set beside the first ones. The neck-to-jaw angle is reviewed with you, along with whether the pad still needs another session and when to book it.

Experience Behind the Series

Kybella in Bronxville and Bridgehampton

Every Kybella session is performed by Catherine Curtin, MSN, FNP-C, who has injected for nearly 20 years. The fullness under the chin is examined by hand and in profile before the dose for a session is set.

Deoxycholic acid breaks down fat cells wherever it reaches, so the edges of the grid matter as much as the dose inside it. The run of the nerve that moves the lower lip is marked out first, and the points are kept away from the jaw border and off the midline.

How much fullness the lower third of the face should lose is the first decision, and the series is sized to it. A profile can be over-reduced as easily as a lip can be over-filled, and fat that has been destroyed does not come back.

Dosing is individual. The pad is mapped and the tissue felt across it, then the series is measured so the neck and jaw still look like themselves as the fullness comes down.

Treatment Process

Your Kybella Series, Step by Step

Every stage of a Kybella series is explained in advance, from the first consultation through the spacing of the later sessions.

Step 01 · Consultation

Consultation and Profile Assessment

The neck and jawline are examined straight on and in profile, and the pad under the chin is pinched to judge how much of it is fat and how far the skin springs back. Medical history is reviewed, including anything affecting swallowing. You leave with a session range and a clear account of the swelling.

Whether Kybella Fits Your Anatomy

Under-chin fullness is not always fat. Loose skin and a chin that sits back from the neck both photograph as a double chin, and each one is treated differently. Which one is shaping your profile is examined at the complimentary consultation.

Complete Profile Assessment

Anatomy first

The first questions are how the jaw and the neck meet and how far the skin recoils when it is released. A pad that is mostly fat moves differently under the fingers from one that is mostly loose skin. That answer decides whether Kybella belongs here, and dosing is worked out after it.

A Measured Series Plan

Treatment mapping

A range of sessions is set at the start from what the anatomy shows, then revisited once the response to the first session is visible. Sometimes that means fewer sessions than the range began with.

Swelling Explained Up Front

Downtime and timing

How swollen and firm the area under the chin gets after a session, how long the visible swelling tends to last, and how to space sessions around work and social plans are all covered in consultation, so the dates are chosen with the swelling in mind.

A full-face assessment comes before any single treatment.

FAQ

Kybella Questions Patients Ask Most

What patients want answered before booking a Kybella consultation in Bronxville or Bridgehampton.

Kybella is given as a series, with sessions spaced weeks apart so the body can finish clearing the fat broken down by the last one. The number depends on how much fullness sits under the chin and how quickly you clear it. Your range is confirmed at the consultation.

Kybella breaks down the fat cells it reaches and the body clears them, so those cells no longer store fat. The cells left behind can still enlarge with weight gain, so the contour under the chin holds at a steady weight.

Swelling and a full, firm feeling under the chin follow every session. Bruising is common, the area can feel numb for a while, and the firmness often outlasts the swelling. Sessions in Bronxville and Bridgehampton are timed around work and social plans for that reason.

Each session uses a conservative dose, and the pad is examined again at the next visit. The series is sized so the lower face keeps some fullness under the jaw. Another session is added only if the pad still needs reducing.

No. Kybella reduces fat and does not change skin quality, and reducing the pad under already loose skin can leave the area looking emptier. Skin laxity is a separate concern with separate treatment, and which one is shaping your profile is assessed at your first visit.

Kybella is FDA-approved for submental fat, the small, well-bordered pad beneath the chin. Broader fullness across the neck or lower face is a different problem and does not reduce with it. The pad is assessed in consultation at either office.

Kybella is a synthetic form of deoxycholic acid, close to the bile acid the body already uses on dietary fat. Placed in a grid through the pad under the chin, it breaks down the walls of those fat cells. Over the following weeks the body clears them and the pad flattens.

No. Filler adds volume to shape and support an area, while Kybella reduces volume. The two can sit in the same treatment plan, with the pad under the chin lightened and filler placed along the jaw so the edge has structure behind it.

Kybella is postponed when there is an active infection in the treatment area or any difficulty swallowing, and during pregnancy and breastfeeding. It is also unsuitable where loose skin is doing more of the work than fat, because reducing the pad would make the laxity more visible.
