A double chin can be caused by very different things — small fat pockets, loose skin, a recessed chin or simply genetics — and what is right for you depends on which of these is driving the fullness under your chin.
Stubborn submental fat, skin and tissue laxity, a recessed chin — alone or combined
Contributing factors
Genetics, age-related collagen loss, weight change, posture and bone structure
Key areas
Under the chin (submental area), the jaw-to-neck angle and the chin–jawline transition
A double chin — known clinically as submental fullness — is the soft fullness that forms beneath the chin, blurring the angle between the jaw and the neck. It is not always caused by weight: it can be small pockets of stubborn fat, loose or lax skin under the chin, a weak or recessed chin that makes the area read heavier in profile, or a combination — and it is often influenced by genetics. Because the cause changes the right treatment, a proper clinical assessment is the only reliable starting point.

Understanding the concern
What is Double Chin (Submental Fullness)?
A double chin is fullness in the submental area — the soft tissue directly beneath the chin and along the top of the neck. When this region loses its crispness, the clean angle between the jawline and the neck softens, and the lower face can look heavier or less defined than it really is, particularly in profile.
What many people do not realise is that a double chin has several quite different causes, and they often coexist. It can be a small, stubborn pocket of fat that sits under the chin regardless of body weight; it can be skin and connective tissue that have lost their firmness and begun to sag; or it can be skeletal — a naturally weak or set-back chin that gives the area less support, so soft tissue is less well held and the profile reads fuller.
This is why there is no single treatment for a double chin. The honest answer depends on the balance of fat, skin laxity and chin projection in your particular face — and on the degree of each. Understanding what is actually driving the fullness matters far more than chasing any one device or injection, and a significant amount of submental fat or loose skin may sit beyond what non-surgical treatment can achieve.
Non-surgical treatments work best for small fat pockets, early skin laxity or a recessed chin. A large amount of submental fat or significant loose skin is beyond non-surgical scope, and weight-related fullness is assessed individually — Dr Nina will tell you honestly at consultation, including whether a surgical opinion is the more appropriate route.
Quick reference
What causes it
Stubborn submental fat, skin and tissue laxity, a recessed chin — alone or combined
Contributing factors
Genetics, age-related collagen loss, weight change, posture and bone structure
Key areas
Under the chin (submental area), the jaw-to-neck angle and the chin–jawline transition
What to consider
The right treatment depends on whether fat, laxity or chin projection is the main driver
Non-surgical vs surgical
Non-surgical suits small fat pockets and early laxity; a large amount of fat or loose skin may need a surgical opinion
Why it happens — three drivers
Submental fat
Small, stubborn pockets of fat can collect beneath the chin and resist diet and exercise. They are often genetic and can be present even at a healthy, stable weight.
Skin & tissue laxity
As collagen and elastin decline with age, the skin and connective tissue under the chin lose firmness and begin to sag, softening the jaw-to-neck angle.
A recessed chin
A naturally weak, small or set-back chin gives the area less structural support and shortens the profile, so the under-chin can read fuller even with little fat.
Where it tends to show up
Soft fullness beneath the chin and along the top of the neck
Loss of the crisp angle between the jaw and the neck
A heavier or less defined lower face, especially in profile
Fullness that persists despite a stable, healthy weight
A short or set-back chin that makes the area look fuller
Loose or crepey skin under the chin with age
Treatment guidance
Matching treatment to your concern
Because a double chin can come from fat, loose skin, a recessed chin or a combination, the treatments that help work in fundamentally different ways — some reduce small fat pockets and tighten skin, some firm and contour the lower face, and others improve the chin projection that supports the whole profile. The right choice, or combination, depends on what is actually driving the fullness in your face. These are the presentations we see most often, and what tends to suit each.
Fat & early laxity
Small fat pockets with early skin laxity
Where the fullness is a small, stubborn pocket of submental fat alongside early loosening of the skin, Endolift® is often well suited — a fine laser fibre placed beneath the skin can reduce small fat pockets while tightening the connective tissue under the chin, with results that build over months as collagen rebuilds. It is best for discrete fullness rather than a heavy double chin.
Skin & contour
Tightening and contouring the lower face
For mild-to-moderate laxity and softening of the lower-face and under-chin contour, InMode Contoura uses radiofrequency to firm and tighten the skin and refine the jawline, with a targeted option to address small pockets of fat under the chin. It is fully non-invasive with no downtime, and works over a short course of sessions.
Profile balance
A weak or recessed chin
Sometimes the issue is not fat at all — a weak, small or set-back chin shortens the profile, so the under-chin reads heavier than it is. Chin Sculpting uses hyaluronic-acid filler to improve chin projection, sharpening the chin–jawline transition and the jaw-to-neck line so the area looks more defined in profile.
Combined approach
A combination of causes
Where facial width, a wide jaw and a double chin appear together, The V-Lift is Dr Nina’s bespoke combination protocol — a personalised plan that may draw on filler, jaw-slimming injections and energy devices such as Endolift® to slim and define the lower face. The mix is decided only after assessing what is driving the fullness.
For a large amount of submental fat or significant loose skin, non-surgical options are unlikely to be sufficient — and Dr Nina will say so clearly at consultation, with a surgical referral where appropriate.
At Facial Sculpting
What happens at your consultation
A consultation is not a commitment to treatment — it is a proper clinical assessment. Here is what to expect.
01
A full clinical assessment
Dr Nina examines what is actually driving the fullness under your chin — the amount of submental fat, the degree of skin laxity, and your chin projection and jaw-to-neck angle in profile. This three-dimensional picture determines whether one treatment, a combination, or a surgical opinion is most appropriate for your anatomy.
02
An honest, specific plan
If a non-surgical treatment is likely to help, she will recommend it specifically, with a clear explanation of why and how results build over time. If there is a large amount of fat or significant loose skin, she will say so — and refer for a surgical opinion rather than offer a treatment she does not believe will deliver a meaningful result.
03
No obligation
Consultations are never upsells. The outcome may be one treatment, a combination plan, or honest advice that a surgical route would serve you better. The goal is the right answer for your anatomy and concern — not a booking.
Many patients benefit from a combination — for example Endolift® to reduce a small fat pocket and tighten the skin, alongside Chin Sculpting to improve projection and the jaw-to-neck line. Dr Nina advises what would genuinely add value, and assesses any combination honestly.
Common questions
FAQs about double chin (submental fullness)
What is the best treatment for a double chin?
There is no single best treatment, because a double chin can be caused by very different things. For small, stubborn fat pockets with early skin laxity, Endolift® can reduce the fat and tighten the skin under the chin. For mild-to-moderate laxity and contour, InMode Contoura firms the lower face with radiofrequency. If a weak or recessed chin is making the area look fuller, Chin Sculpting improves projection and the jaw-to-neck line. A large amount of fat or loose skin may need a surgical opinion. Dr Nina assesses what is actually driving your fullness before recommending anything.
Can a double chin be treated without surgery?
Often, yes — provided the fullness is from small fat pockets, early skin laxity or a recessed chin rather than a large volume of fat or significant loose skin. Treatments such as Endolift® (which can reduce small fat pockets and tighten under the chin), InMode Contoura (radiofrequency tightening) and Chin Sculpting (to improve chin projection) are designed for exactly these situations. For a heavy, fat-driven double chin or marked skin excess, non-surgical options are unlikely to be sufficient and a surgical consultation is more appropriate. Dr Nina will tell you honestly which category applies to you.
What causes a double chin?
A double chin, or submental fullness, has several possible causes that often coexist. It can be a small, stubborn pocket of fat beneath the chin — frequently genetic and present even at a stable, healthy weight. It can be skin and connective tissue that have lost firmness with age and begun to sag. It can also be skeletal: a naturally weak or set-back chin gives the area less support, so the profile reads fuller even with little fat. Weight, posture and genetics all play a part. Because the cause changes the right treatment, an individual assessment matters.
Is a double chin always caused by weight?
No. While weight can contribute, many people have a double chin at a perfectly healthy, stable weight. Stubborn submental fat pockets are often genetic and resist diet and exercise. A double chin can also be caused by skin laxity as collagen declines with age, or by a naturally weak or recessed chin that makes the under-chin area look fuller in profile. This is why assessment matters: the right treatment depends on whether fat, loose skin or chin projection is the main factor, and weight-related fullness is assessed individually.
Does Endolift help a double chin?
Endolift® can help certain double chins. A fine laser fibre is placed just beneath the skin, delivering controlled heat that can reduce small, stubborn pockets of submental fat while also tightening the connective tissue and skin under the chin. This makes it well suited to discrete fullness combined with early skin laxity. It is not designed for a heavy, fat-driven double chin or significant loose skin, where a surgical opinion may be more appropriate. Results build gradually over the months after treatment as collagen rebuilds, rather than appearing immediately.
Can chin filler help a double chin?
It can, when the appearance of a double chin is partly caused by a weak, small or recessed chin. A set-back chin shortens the profile and gives the under-chin area less support, so it can read heavier than it is. Chin Sculpting uses hyaluronic-acid filler to improve chin projection, which sharpens the chin–jawline transition and the jaw-to-neck line, making the area look more defined in profile. If the fullness is mainly submental fat or significant skin laxity, a tightening or fat-reducing approach is more appropriate — Dr Nina will advise which applies to you at consultation.
Does InMode Contoura reduce a double chin?
InMode Contoura can help refine a double chin where the cause is mild-to-moderate skin laxity and contour. Its radiofrequency energy firms and tightens the skin and defines the jawline, and a targeted option can address small, stubborn pockets of fat under the chin while tightening the overlying skin. It is fully non-invasive with no downtime and is given as a short course of sessions. It is not a weight-loss treatment and is best for discrete fullness rather than a heavy double chin — your anatomy is assessed at consultation to confirm whether it suits you.
How is Endolift different from InMode Contoura for a double chin?
They tighten and refine the under-chin in different ways. InMode Contoura is fully non-invasive radiofrequency delivered through the skin surface, with no downtime, over a course of sessions — well suited to mild-to-moderate laxity and contour. Endolift® is minimally invasive: a fine laser fibre is placed just beneath the skin under local anaesthetic, giving more direct tightening and the ability to reduce small fat pockets, with about a day of downtime. Endolift® tends to suit discrete fat with early laxity; InMode Contoura suits those preferring a needle-free, no-downtime course. Dr Nina advises which fits your anatomy.
When will I see results from double chin treatments?
It depends on the treatment. Energy-based treatments work gradually: with Endolift®, the connective tissue retracts early but the firming and fat reduction build over the following months as collagen rebuilds, with optimal results for most patients around six months. InMode Contoura is felt early, with firmness and definition developing session by session over a course and refining for weeks afterwards. Chin Sculpting shows an immediate change in projection that settles over a few weeks. Results from energy treatments build over time rather than appearing instantly, so a little patience is part of the process.
Can a double chin be a combination of causes?
Frequently, yes — and this is one of the most important things to assess. Many people have a small fat pocket and early skin laxity together, or a recessed chin alongside soft tissue under the chin. Where facial width, a wide jaw and a double chin appear together, The V-Lift is Dr Nina’s bespoke combination protocol, drawing on filler, jaw-slimming injections and energy devices such as Endolift® to slim and define the lower face. The right combination is decided only after assessing what is driving the fullness, and any combination is recommended honestly rather than to add cost.
When does a double chin need surgery instead?
Non-surgical treatments work best for small fat pockets, early skin laxity or a recessed chin. Where there is a large amount of submental fat or significant loose skin, non-surgical options are unlikely to deliver a meaningful result, and a surgical opinion — for example liposuction or a procedure to remove excess skin — may be more appropriate. Weight-related fullness is assessed individually. At Facial Sculpting, Dr Nina will tell you plainly if your concern falls outside the non-surgical scope and refer you for a surgical assessment rather than offer a treatment she does not believe will help.
How much do double chin treatments cost in London?
Cost depends on which treatment suits the cause of your fullness and how much is needed, so the right figure is confirmed only after a clinical assessment. Endolift®, InMode Contoura, Chin Sculpting and The V-Lift are priced differently because they work in different ways and involve different numbers of sessions. At Facial Sculpting the focus is on value rather than a headline number: Dr Nina recommends only what would genuinely help, and confirms your individual plan and its price at consultation, with no obligation to proceed.

"I had EndoLift with Dr Nina at her clinic. I just wanted to share my experience With anyone who is looking to get endo lift or any other procedure done with Dr Nina. She is absolutely amazing so gentle and so kind she is so experienced in her field and knows whats best for you without trying to oversell you rather only whats needed. I was looking for this treatment for my double chin and picked the best place for it! it was a very comfortable treatment took about 30 mins. It permanently dissolves the fat there and tightens the area. She always checked on me to make sure im feeling ok. Its a week now and i can slowly see a difference im a little swollen and sore but the swelling is not noticeable to anyone. Cant wait for full results. Thank you Dr Nina."

I was introduced to Dr Nina by a friend and I can’t rate her professionalism and work highly enough. Dr Nina put me at my ease from the first moment we met. I was feeling very problemed with my jawline and marionette lines on either side of my mouth Dr Nina prescribed Endolift facial sculpting. Within under one hour of me lying on her couch for the treatment I looked like a new woman. To say that I was exceedingly pleased with the procedure is an understatement. I will definitely be returning for further Endolift work, and actually sharing this fabulous clinician with good friends KB LONDON

If I could leave more than five stars I would! Dr Nina’s clinic is warm and welcoming, in a beautiful location close to Knightsbridge station. I had cheek fillers for the first time and my face was numbed prior. I was expecting to find it a little uncomfortable but honestly there was barely any pain at all. The needles are so fine, and Dr Nina was very gentle. I will be back as I know I am in good hands!

Dr. Nina and the team are experts and kind and friendly. Highly recommend.
A double chin is one of the most misunderstood concerns in aesthetics — patients are often offered a single fix without anyone asking whether the cause is fat, loose skin or a recessed chin. Dr Nina’s approach is different: diagnose the driver first, treat the right thing, and be honest about what non-surgical treatment can and cannot do.
Diagnose the cause first
Submental fullness can be fat, laxity, a weak chin or a combination. Dr Nina identifies what is actually driving it before recommending anything, rather than defaulting to one treatment.
Honest about limits
If there is a large amount of fat or significant loose skin, we say so plainly and refer for a surgical opinion where appropriate. Your outcome matters more than a booking.
Natural, gradual results
A less-is-more philosophy focused on refining the jaw-to-neck line gradually and naturally — energy-based results build over time, and we set expectations honestly.
“In my practice, I focus on addressing life’s moments and the emotions they carry, rather than merely correcting lines and imperfections. I aim to provide therapies that respect and reflect the individual’s personal story.”
