What Causes Pre-Jowl Hollows?
Introduction
A pre-jowl hollow is the indentation that can develop between the chin and the jowl along the lower jawline. It can make the jawline look less smooth and may become more noticeable as the face ages. Although it is sometimes described simply as “volume loss,” the underlying cause can be more complicated.
Pre-jowl hollows can develop because of changes in facial volume, soft-tissue descent, skin laxity, changes in the chin and jaw structure, and the natural anatomy of the lower face. Weight loss can also make the contour more visible. Because several factors may occur at the same time, treating the hollow without assessing the surrounding jowl and chin can produce an unbalanced result.
What Exactly Is a Pre-Jowl Hollow?
The pre-jowl area is located immediately in front of or beside the jowl, near the transition between the lower cheek and chin.
In a younger-looking lower face, this transition may appear relatively continuous.
With aging, you may begin to see:
lower cheek → jowl → indentation → chin
That indentation is commonly called the pre-jowl sulcus.
It can be subtle at first and become increasingly noticeable when you look at your face from the side or under certain lighting.
Why Do Pre-Jowl Hollows Develop?
1. Age-Related Facial Volume Changes
One of the most important contributors is changing facial volume.
Facial fat compartments can lose volume, shift, or become more prominent relative to neighboring areas as the face ages. This can create differences in contour that were less visible when you were younger.
However, facial aging is not simply a matter of “losing fat everywhere.”
Some areas may lose volume while other areas become more prominent.
This is why a person can simultaneously have a hollow beside the chin and a fuller-looking jowl.
2. Soft-Tissue Descent
As facial support changes, tissues can gradually descend toward the lower face.
This contributes to jowling and can make the pre-jowl depression more noticeable.
In other words, the hollow may not exist because the area itself has dramatically lost volume. Instead, the surrounding tissues may have changed position.
This distinction is important when considering treatment.
3. Changes in the Chin and Mandible
The underlying facial skeleton also changes with age.
Changes involving the mandible and chin can alter the framework supporting the lower-face soft tissues. This can influence the contour between the chin, lower lip, jowl, and jawline.
The visible hollow is therefore not always purely a skin or fat problem.
4. Skin Laxity
Aging skin gradually loses some of its elasticity and structural support.
When the skin becomes less firm, small differences in underlying contour can become more obvious.
Skin laxity can also make nearby jowls more prominent, increasing the visual contrast between the jowl and pre-jowl region.
5. Weight Loss
Significant weight loss can reveal or exaggerate pre-jowl hollows.
When facial volume decreases, areas that previously blended together may become more sharply defined.
This can be particularly noticeable if you lose weight relatively quickly or have naturally lean facial features.
If your weight is still changing, however, the appearance of your lower face may continue to change.
6. Natural Facial Anatomy
Not every pre-jowl hollow is caused by aging.
Some people naturally have a slight indentation beside the chin because of their underlying bone structure, fat distribution, or soft-tissue anatomy.
If the hollow has been present for many years, it may be more accurate to think of it as an anatomical feature rather than an aging defect.
Why Does the Hollow Sometimes Become More Noticeable in Your 40s or 50s?
Aging-related changes accumulate gradually.
You may not notice anything for years and then suddenly see a change in photographs.
This can happen because several relatively subtle changes begin interacting:
- Less facial volume
- More visible jowling
- Reduced skin elasticity
- Changes around the chin
- Lower-face tissue descent
- Changes in lighting and facial angles
The result can be a much more noticeable contour even though no single change happened suddenly.
Is a Pre-Jowl Hollow the Same as a Jowl?
No.
A jowl is the area of soft tissue that becomes more prominent along the lower jawline.
A pre-jowl hollow is the depression adjacent to it.
They frequently appear together.
This relationship matters because filling the hollow does not necessarily eliminate the jowl. Likewise, tightening the jowl does not necessarily recreate lost volume in the hollow.
A complete lower-face assessment should consider both.
Can Pre-Jowl Hollows Be Caused by Filler?
Previous cosmetic treatment can influence lower-face contours.
For example, filler placed elsewhere in the face can change the balance between adjacent areas. Old filler may also contribute to fullness in certain regions.
If you have had previous filler, tell your clinician:
- Where it was injected
- Approximately when it was injected
- What product was used, if known
- Whether you had complications
- Whether additional filler was subsequently added
This information can change the treatment assessment.
Can Filler Treat a Pre-Jowl Hollow?
Yes, carefully selected patients may benefit from filler.
The purpose is usually to smooth the transition between the jowl and chin, not to make the entire lower face fuller.
The clinician needs to consider the depth of the hollow, chin projection, jowl size, skin laxity, and overall facial proportions.
Adding too much volume can make the lower face appear heavier.
For that reason, a conservative approach is often more appropriate than attempting to completely erase every contour.
What If I Don't Want Filler?
There are alternatives, although they work differently.
Radiofrequency Tightening
RF may be considered when skin laxity and lower-face tissue quality are contributing to the appearance.
It does not directly replace missing volume but may improve the surrounding contour in appropriate patients.
Ultrasound-Based Tightening
Certain ultrasound-based treatments can target deeper tissue layers and may be considered for selected patients with laxity.
However, people with thin or volume-deficient faces need careful assessment before undergoing aggressive tightening.
RF Microneedling
RF microneedling may help with skin texture and mild laxity.
It is not a direct replacement for structural filler when a deep pre-jowl depression is primarily caused by volume deficiency.
Collagen-Stimulating Treatments
Some collagen-stimulating treatments may be discussed when the main concern is declining skin quality.
These generally aim for gradual improvement rather than immediate contour correction.
Could Tightening Actually Make a Hollow Look Worse?
This is an important question, particularly if your face is already thin.
If a hollow is primarily related to volume deficiency, a treatment designed mainly to tighten tissue may not correct the depression.
In some situations, aggressive treatment of a thin lower face may make existing contours appear more pronounced.
That does not mean tightening treatments are inherently inappropriate. It means treatment should be matched to your facial volume, skin thickness, and degree of laxity.
What About Chin Filler?
Chin filler and pre-jowl filler are not interchangeable.
Chin filler primarily changes the projection or contour of the chin.
Pre-jowl treatment focuses on the transition beside the chin.
A clinician may evaluate both because chin projection can influence the appearance of the entire lower face, but treating the chin does not automatically correct the pre-jowl hollow.
Can Exercise or Facial Massage Remove Pre-Jowl Hollows?
There is no reliable evidence that facial exercises can structurally eliminate an established pre-jowl depression caused by aging-related volume or skeletal changes.
Massage may temporarily change swelling or fluid distribution, but it should not be expected to permanently restore lost volume or reposition descended facial tissue.
Be cautious about claims that a particular exercise or massage technique can permanently “erase” jowls or pre-jowl hollows.
When Is Surgery Considered?
If a pre-jowl hollow is accompanied by significant jowling and lower-face tissue descent, nonsurgical treatments may have limitations.
A qualified facial plastic surgeon can evaluate whether a lifting procedure would address the underlying tissue descent more directly.
Surgery is not automatically necessary for a pre-jowl hollow. It becomes more relevant when structural laxity is substantial and nonsurgical treatment cannot reasonably provide the desired degree of correction.
How Can You Tell What Is Causing Your Hollow?
A clinician should evaluate your face at rest and from different angles.
A useful assessment considers:
FindingWhat it may suggestHollow present since youthNatural anatomyHollow appeared after weight lossVolume changeHollow + prominent jowlTissue descent and contour changeHollow + loose skinSkin laxityHollow + weak chin projectionChin/jaw structureHollow + previous fillerTreatment-related contour changes may need assessment
These findings can overlap, so they should not be treated as a self-diagnosis.
What Should You Ask a Seoul Dermatology Clinic?
If you are considering treatment in Seoul, ask for an assessment of the entire lower face, not just the indentation.
Useful questions include:
- Is this a true pre-jowl hollow?
- Is it caused mainly by volume loss or tissue descent?
- How significant are my jowls?
- Would filler make my lower face look heavier?
- Could tightening improve the surrounding tissue?
- Is my chin structure contributing to the appearance?
- Would you recommend treating the hollow, the jowl, or both?
- How much improvement is realistic without overcorrecting the area?
For international patients, providing previous treatment records can make the consultation more informative.
Conclusion
Pre-jowl hollows develop for several reasons, and aging-related volume changes are only one piece of the picture. Soft-tissue descent, jowling, skin laxity, changes in the chin and jaw, weight loss, and natural anatomy can all influence the contour.
This is why simply asking for “pre-jowl filler” may not always produce the most appropriate treatment plan.
If the depression is primarily a volume problem, carefully selected filler may help. If surrounding laxity is more important, tightening may be considered. If significant tissue descent is present, surgical assessment may provide a more complete understanding of the options.
The most useful first step is to determine why your pre-jowl hollow has become visible before deciding how to treat it.
FAQs
What is a pre-jowl hollow?
A pre-jowl hollow is an indentation beside the chin and adjacent to the jowl along the lower jawline. It is commonly referred to as the pre-jowl sulcus.
Does everyone develop pre-jowl hollows with age?
No. Some people naturally have this contour, while others develop it as facial volume, soft tissues, skin elasticity, and underlying structures change.
Can weight loss cause pre-jowl hollows?
Significant weight loss can reduce facial volume and make a previously subtle pre-jowl depression more visible.
Can RF tighten a pre-jowl hollow?
RF may improve surrounding skin laxity and tissue quality, but it generally cannot directly replace substantial lost volume.
Does pre-jowl filler remove jowls?
Not necessarily. Filler can soften the indentation, but it does not directly lift significantly descended tissue.
Can a pre-jowl hollow be treated without filler?
Potentially. Depending on the cause, options may include RF, ultrasound-based tightening, RF microneedling, collagen-stimulating treatments, or surgical evaluation.
