Why Is the Area Beside My Chin Becoming Hollow?

Introduction

If you have started noticing a small depression or hollow area beside your chin, you may be seeing what is often called a pre-jowl hollow or prejowl sulcus. This area can become more noticeable with age as changes occur in facial fat, soft-tissue support, bone structure, and skin elasticity.

A hollow beside the chin does not automatically mean that you need filler. The appearance can result from true volume loss, neighboring tissue descent, changes in the chin and jawline, or a combination of these factors. Understanding the cause is important because adding volume to the wrong location can make the lower face look heavier rather than younger.

What Is the Hollow Beside the Chin?

The depression between the lower cheek/jowl area and the chin is commonly referred to as the pre-jowl sulcus.

It is located near the front portion of the lower jawline, beside the chin.

In a younger face, the transition from the cheek to the chin may appear relatively smooth. With aging, a visible indentation can develop, creating a contour that looks something like:

cheek → jowl → hollow → chin

This can make the jawline appear less continuous.

Why Does a Pre-Jowl Hollow Develop?

Several aging processes can contribute.

1. Changes in Facial Volume

Facial fat does not simply disappear evenly throughout the face.

Different fat compartments can change in volume and position at different rates. Loss of support around the lower face can therefore create a localized depression.

2. Soft-Tissue Descent

As supporting tissues become less resilient, tissue can descend toward the lower face.

This can make the jowl more prominent while simultaneously making the area immediately in front of or beside it look hollow.

This is an important distinction: the hollow and the jowl may be two sides of the same aging process.

3. Changes in the Jawbone

The facial skeleton also changes with age.

Changes in the mandibular and chin region can affect the underlying framework supporting the soft tissues. This can alter the contours around the mouth and jawline.

4. Skin Laxity

Reduced collagen and elastin can make the skin less firm.

Even a relatively small anatomical depression may become more visible when the surrounding tissue loses its youthful tension.

Why Does It Sometimes Appear Suddenly?

You may feel that the hollow appeared almost overnight, even though facial aging is usually gradual.

Several things can make an existing contour suddenly more noticeable:

• Weight loss
• Changes in facial volume
• Increasing jowling
• Menopausal or age-related changes
• Reduced skin elasticity
• Changes in lighting
• Weight fluctuations
• Previous cosmetic treatments

Weight loss is particularly relevant because reduced facial volume can make previously subtle contours more obvious.

Is the Hollow Actually Empty?

Not necessarily.

The word “hollow” can be misleading.

A visible depression may be caused by a combination of tissue loss and tissue accumulation nearby. For example, a jowl can become more prominent while the area beside the chin becomes more indented.

This means simply adding a large amount of filler into the depression may not always produce the most natural-looking result.

A clinician should examine the entire lower-face contour.

Can Pre-Jowl Filler Correct the Hollow?

In selected patients, carefully placed filler can soften a pre-jowl depression.

The objective is usually not to create a prominent chin or make the lower face look fuller. Instead, the clinician may use a relatively small amount of product to create a smoother transition between the jowl and chin.

The treatment approach depends on:

• Depth of the depression
• Chin projection
• Jawline shape
• Jowl position
• Skin laxity
• Existing filler
• Facial proportions

The lower face has important blood vessels and nerves, so filler injections should be performed by an appropriately qualified professional familiar with facial anatomy.

Could Filler Make My Lower Face Look Heavier?

Yes, this is an important consideration.

If the hollow is relatively mild, adding too much filler can create excessive fullness.

This can be especially noticeable if you already have:

• Jowls
• Lower-face puffiness
• A short or wide lower face
• Existing filler
• Significant skin laxity

The goal should be contour correction, not simply filling the largest possible amount of space.

What If I Don't Want Filler?

You still have options, although they may address different aspects of the problem.

Radiofrequency Tightening

RF treatments may improve mild skin laxity and tissue quality.

If the hollow is becoming noticeable partly because of lower-face descent, improving surrounding tissue tightness may change the overall contour.

However, RF does not directly replace substantial lost volume.

Ultrasound-Based Tightening

Selected ultrasound-based treatments may be used to address tissue laxity.

Whether they are appropriate depends on your facial thickness, degree of laxity, and overall facial volume.

Someone with a naturally thin or volume-deficient face may need a particularly careful assessment before aggressive tightening.

RF Microneedling

RF microneedling may improve skin texture and some aspects of mild laxity.

It is more appropriate for skin quality than for a true deep structural depression.

Collagen-Stimulating Treatments

Some patients may discuss collagen-stimulating treatments when their main concern is declining skin quality.

These treatments generally aim to improve tissue quality over time rather than provide the immediate contouring effect of a structural filler.

Could Treating the Jowl Be More Important Than Filling the Hollow?

Sometimes.

Imagine a lower face where the jowl has descended while the pre-jowl region has become indented.

If you only fill the indentation, the jowl may remain prominent.

The final result could therefore still look aged despite the hollow being less obvious.

This is why some patients need an assessment of:

chin + pre-jowl sulcus + jowl + jawline

rather than treating one point in isolation.

What About Chin Filler?

Chin filler is not the same as pre-jowl filler.

Chin augmentation changes the projection or shape of the chin itself.

Pre-jowl treatment primarily addresses the transition beside the chin.

Sometimes both areas are evaluated because chin projection can influence the overall lower-face balance.

But they should not automatically be treated together.

Can Weight Loss Cause or Worsen the Hollow?

Yes, significant weight loss can make pre-existing lower-face contours more visible.

When facial volume decreases, the transition between the jowl, pre-jowl area, and chin can become more pronounced.

If your weight is still changing, it may be worth discussing whether the facial contour is likely to continue changing before committing to substantial volume restoration.

How Do I Know What Treatment I Need?

A useful assessment should look at your face from multiple angles and during movement.

These are categories for discussion, not a universal treatment formula.

What Should I Ask a Seoul Dermatologist?

If you are considering treatment in Seoul, ask the clinic to evaluate the entire lower face rather than simply requesting “pre-jowl filler.”

Useful questions include:

1. Is this actually a pre-jowl hollow?
2. Is volume loss or tissue descent causing it?
3. Do my jowls contribute to the appearance?
4. Would filler make my lower face look heavier?
5. Would tightening be useful instead?
6. Do I have existing filler in the area?
7. How much correction is realistically possible without overfilling?
8. Would treating my chin change the overall contour?

If you are an international patient, tell the clinic about previous filler, weight changes, Botox, and energy-based treatments.

When Is Surgery Worth Discussing?

If the main issue is substantial jowling and tissue descent rather than a small localized depression, nonsurgical treatment may have limitations.

A qualified facial plastic or oculoplastic/facial aesthetic surgeon can assess whether a surgical lifting procedure would address the underlying tissue descent more directly.

That does not mean surgery is required. It simply provides another option when the structural component is significant.

Conclusion

The hollow beside your chin may be a pre-jowl sulcus, but the visible depression is often part of a larger change in lower-face structure. Aging can involve volume changes, soft-tissue descent, skin laxity, and skeletal changes simultaneously.

Pre-jowl filler can soften a localized depression in selected patients, but more filler is not automatically better. If jowling or lower-face laxity is also present, tightening or broader structural treatment may be more appropriate.

The best starting point is therefore to determine whether you are dealing with a true volume deficit, a contour created by nearby tissue descent, or both.

FAQs

What causes a hollow beside the chin?

Common contributors include facial volume changes, soft-tissue descent, skin laxity, changes in the chin and jaw structure, and aging-related changes in the lower face.

Is a hollow beside the chin the same as a pre-jowl hollow?

Often, yes. A depression between the jowl and chin is commonly described as the pre-jowl sulcus or pre-jowl hollow.

Can filler fix a pre-jowl hollow?

Carefully placed filler can soften the depression in selected patients. The amount and placement should be conservative because excessive filler can make the lower face look heavier.

Can weight loss make pre-jowl hollows worse?

Significant weight loss can reduce facial volume and make previously subtle depressions more visible.

Can skin tightening fix a pre-jowl hollow?

Tightening treatments may improve surrounding laxity but generally cannot replace substantial lost volume. Their usefulness depends on what is causing the contour change.

Should I fill the hollow or treat the jowl?

There is no universal answer. If both a hollow and jowl are present, the entire lower-face contour should be assessed before deciding which component to address.
