What Actually Causes Jowls? A Doctor-Led Guide for Surrey Patients – by Dr Raj Dhillon
Jowls rarely appear out of nowhere. More often, the first sign is a jawline that looks slightly softer in photographs, a little heaviness beside the chin or a lower face that no longer has quite the definition it once did.
It’s tempting to put all of this down to loose skin, but that’s only part of the story.
The face changes at several levels as we age. Collagen reduces, fat compartments shift, supporting ligaments change and even the bones beneath the face gradually lose some of their structure. Add genetics, sun exposure and changes in weight into the mix and it becomes easier to understand why two people of the same age can have completely different jawlines.
It also explains why treating jowls isn’t as simple as adding filler to the area that’s dropped.
At Revital Lab in Esher, we look at what is actually creating the heaviness or loss of definition before deciding how best to approach it.
What Are Jowls?
Jowls are the areas of sagging or heaviness that develop along the lower jaw, usually on either side of the chin.
In a younger face, skin, fat and the deeper facial tissues are held in a relatively stable position. The jawline tends to have a smoother, more defined transition between the cheek and chin.
Over time, that support changes.
Skin becomes less elastic, facial tissues begin to descend and the underlying structure of the face alters. Eventually, tissue can start to collect around the lower face and interrupt what was previously a fairly straight jawline.
The visible jowl is therefore often the result of several changes happening together rather than one isolated problem.
Why Do We Develop Jowls?
We Produce Less Collagen and Elastin
Collagen provides strength and structure to the skin, while elastin helps it return to position after it stretches.
Our production of both declines with age. As a result, skin gradually becomes thinner, less firm and less able to resist the effects of gravity.
Years of UV exposure can accelerate this process because ultraviolet radiation contributes to collagen and elastin breakdown. This is one reason the face, neck and décolletage often show signs of ageing earlier than areas that have spent more time protected from the sun.
When collagen loss is significant around the lower face, the skin has less support and jowling can become more noticeable.
But collagen isn’t the only thing changing.
Facial Fat Doesn’t Stay in the Same Place
We tend to think of facial fat as a single layer underneath the skin. In reality, it is arranged in separate compartments.
Those compartments change with age. Some lose volume while others descend or become more prominent.
Loss of volume higher in the face can reduce support through the cheek and mid-face, while tissue lower down begins to contribute to heaviness around the jaw.
This is why treating the visible jowl itself isn’t always the most sensible solution. Sometimes what we’re seeing at the jawline has been influenced by changes elsewhere in the face.
The Supporting Structures of the Face Change Too
There are ligaments beneath the skin that help anchor and support the facial tissues.
These aren’t immune to ageing.
As the deeper support system changes and tissues descend, folds around the mouth and lower face can become more obvious. The jawline gradually loses some of the definition it had previously.
Even the facial skeleton changes throughout adulthood.
Bone around the jaw and chin provides an important foundation for the soft tissues above it. Gradual changes to this structure can reduce that support at the same time as the skin and deeper tissues are becoming more lax.
This combination is what often creates the familiar lower-face changes associated with ageing.
Why Do Some People Get Jowls Earlier?
There isn’t a particular age at which everybody suddenly develops jowls.
One person may start noticing them in their late 30s or 40s, while another retains a naturally defined jawline much later.
Genetics make a difference. Facial shape, chin projection, jaw structure, skin thickness and the way facial fat is distributed are all partly inherited.
Lifestyle matters too. Long-term sun exposure contributes to collagen breakdown, while smoking has well-established effects on skin ageing.
Significant fluctuations in weight can also change the appearance of the lower face.
Can Weight Loss Make Jowls More Noticeable?
It can.
Losing weight doesn’t necessarily cause jowls, but losing facial volume can reveal skin laxity that was already there.
This is particularly noticeable following substantial or rapid weight loss. If the skin has good elasticity, it may adapt relatively well. Where collagen has already reduced and the skin is less able to contract, there can be more visible looseness around the cheeks, jawline and neck.
The distinction is important because replacing every bit of lost volume with filler isn’t necessarily the best answer.
If the lower face is already heavy or lax, continually adding volume can sometimes work against what the patient is trying to achieve.
Can You Prevent Jowls?
We can’t stop the structural ageing of the face completely, and genetics will always influence how an individual ages.
There are, however, things worth doing.
Daily broad-spectrum SPF helps reduce additional UV-related collagen damage. A sensible skincare routine containing evidence-based ingredients such as retinoids can support skin quality and collagen production over time.
Avoiding smoking and maintaining a relatively stable weight can also help.
None of these will guarantee that you’ll never develop jowls, but preserving the quality of the skin gives it a better starting point as the deeper facial structures change.
So, What Can Be Done About Jowls?
This is where identifying the cause becomes particularly useful.
If jowling is primarily related to a loss of structural support, the treatment plan may look very different from that of someone whose main issue is loose skin and lower-face heaviness.
At Revital Lab, EndoDefine is one of our main treatments for suitable patients concerned about jowls and loss of jawline definition, particularly when skin laxity is an important part of the problem.
EndoDefine for Jowls and the Lower Face
EndoDefine is a minimally invasive laser treatment that works beneath the surface of the skin.
A very fine laser fibre is introduced beneath the skin so controlled laser energy can be delivered directly into the tissues. The treatment is designed to stimulate collagen production and encourage tissue contraction.
Where appropriate, it can also target small pockets of unwanted fat.
This combination makes EndoDefine particularly relevant to the lower face because jowls are often caused by more than one thing. There may be loose skin, declining collagen and a degree of localised fullness all contributing to the loss of definition.
Rather than adding volume to disguise the area, EndoDefine can address the tissue itself.
It can be used to treat areas including the jowls, jawline, lower face, under the chin and neck.
The aim isn’t to create an unnaturally sharp jawline. It’s to improve firmness and definition while keeping the face looking like the person it belongs to.
Why Do We Often Use EndoDefine for Jowls?
One of the limitations of dermal filler is that it cannot tighten loose skin.
Filler is extremely useful when it is being used for the right reason, but adding more volume to a lower face that is already heavy isn’t always helpful.
EndoDefine works differently.
The laser energy causes a tissue response in the treated area while stimulating new collagen production. The improvement therefore isn’t just about what happens on the day of treatment. Collagen remodelling continues afterwards and the result develops progressively over the following months.
For patients with mild to moderate jowling who aren’t ready for surgical treatment, it can offer an option between injectable treatments and a facelift.
There are limits, of course. EndoDefine isn’t surgery and shouldn’t be presented as a replacement for a facelift in someone with significant excess skin or advanced laxity.
A good consultation includes being clear about that.
What If Fat Is Making the Lower Face Look Heavy?
Not every jowl is purely loose skin.
A small amount of localised fat around the lower face or beneath the chin can blur the jawline and make jowling appear more pronounced.
For an appropriate patient, EndoDefine allows Dr Raj to consider this at the same time as skin laxity.
This is useful because reducing fat without considering the condition of the overlying skin isn’t always ideal. If the skin is already loose, removing volume alone has the potential to make that laxity more apparent.
With EndoDefine, localised fat can be addressed where necessary while controlled laser energy is also used to encourage tissue contraction and collagen production.
Does Dermal Filler Still Help Jowls?
Absolutely, when loss of structure is contributing to the problem.
Someone with reduced chin projection or loss of support around the jawline may benefit from carefully placed dermal filler. Restoring structure in the right areas can improve facial proportions and make the jawline appear more balanced.
That doesn’t mean putting filler directly into the jowl.
Dr Raj may look at the chin, jawline, cheeks and mid-face to understand where support has been lost before deciding whether filler has a role.
The easiest way to understand the distinction is that the treatments are doing different jobs.
Dermal filler restores or creates structural support. EndoDefine addresses tissue laxity, stimulates collagen and can target localised fat where appropriate.
Sometimes one is enough. Sometimes they can be used as part of a staged treatment plan.
What About Collagen-Stimulating Treatments?
Collagen stimulators can also form part of a longer-term plan for facial ageing.
Treatments such as Sculptra are designed to stimulate the body’s own collagen production gradually rather than simply providing the immediate volume associated with traditional hyaluronic acid filler.
They can be useful where collagen loss and broader changes in facial support are part of the picture.
They aren’t, however, interchangeable with EndoDefine.
If actual skin laxity and lower-face heaviness are the primary concerns, Dr Raj may prioritise EndoDefine and then consider treatments for collagen and overall skin quality once the area has settled.
It comes back to treating what is actually there rather than choosing a treatment because it happens to be popular.
How Long Does It Take to See EndoDefine Results?
Although some initial tightening may be noticeable relatively early, the final result isn’t something to judge immediately after treatment.
New collagen takes time to develop.
The lower face can continue to change over the following months as collagen remodelling takes place, with the jawline gradually appearing firmer and better defined.
That gradual progression is part of the appeal for patients who want a natural result. There isn’t necessarily an obvious overnight change that announces you’ve had a treatment.
Do You Always Need to Treat the Jowl Itself?
No, and this is an important part of treating the lower face well.
Patients understandably point to the jowl because that’s what they see in the mirror. We are looking at more than that small area.
He will consider the cheeks, chin, jawline, skin quality, volume distribution, degree of laxity and overall facial proportions.
The eventual recommendation might be EndoDefine to address laxity through the lower face. Another patient might need additional structural support. Someone else may benefit from improving collagen and skin quality alongside their main treatment.
Equally, there will be patients whose degree of laxity means non-surgical treatment is unlikely to deliver the result they want.
Knowing when not to treat is just as important.
What Is the Best Treatment for Jowls?
There isn’t a useful answer to that question until we know what’s causing them.
Two people can stand side by side with similar-looking jowls but have very different anatomy underneath. One may have predominantly loose skin and descending tissue. Another may have lost structural support around the chin and jaw. A third may have a combination of laxity, localised fat and facial volume loss.
For suitable patients at Revital Lab, EndoDefine is a key treatment for jowls because it can address several of the changes commonly responsible for a heavier, less defined lower face without simply adding more volume.
But that doesn’t make it automatically right for everybody.
The assessment comes first.
Treating Jowls at Revital Lab in Esher, Surrey
If you’ve started noticing jowls, lower-face heaviness or a jawline that isn’t as defined as it once was, a consultation is the best place to begin.
We will assess the skin, underlying facial structure, volume distribution, degree of laxity and any localised fullness before discussing what could realistically be improved.
For many suitable patients where laxity is driving the change, EndoDefine may form the main part of the treatment plan. Dermal filler or collagen-stimulating treatments can be incorporated where there is a genuine reason to use them rather than simply adding more treatment.
The aim is straightforward: understand why the lower face has changed first, then decide whether there is a sensible way to improve it.
