Common Questions in Double Chin Lifting Consultations: Why Does Sagging Occur Under the Chin?
Learn why sagging under the chin and double chins develop, often due to fat accumulation, reduced skin elasticity, and jaw structure, not just weight.

Hello,
I am Dr. Park Jung-geun,
Director of Faceplus Plastic Surgery Clinic,
specializing in double chin lifting.

During consultations, many people wonder
why the area under their chin appears saggy.
Facial contours are not solely determined by bone structure;
they are created by the combined effects of
fat, muscles, and skin elasticity.

When this balance shifts, the jawline can appear blurred,
or a double chin may become more prominent.
Especially as we age, reduced skin elasticity often leads to
downward sagging.
If fat under the chin increases or the tissues supporting the jaw
weaken, it can become even more noticeable.

Therefore, it's often difficult to explain it solely
by weight issues.
In actual consultations, there are many cases where the jawline
appears compromised regardless of body type.
In such instances, simple fat reduction alone may not be sufficient.
Structural Causes of a Double Chin
There are several main reasons why sagging appears under the chin.

The first is fat accumulation.
The area under the chin is where fat tends to accumulate relatively easily,
so a double chin can be emphasized with changes in weight.
The second is reduced skin elasticity.
As collagen and elastic fibers decrease,
the skin becomes more prone to sagging.

The third is jaw structure.
If the chin is short or recessed, a double chin can appear more prominent
even under the same conditions.
Finally, lifestyle habits can also play a role.

Prolonged periods of looking down at a smartphone
can cause the tissues under the chin to stretch.
When these various factors act together, the jawline becomes
blurred, and a double chin becomes noticeable.
When Double Chin Thread Lifting is Considered
If sagging under the chin is related to reduced skin elasticity,
thread lifting may be considered.


Thread lifting is a method that supports sagging tissues upwards
to refine the jawline.
Unlike methods that simply reduce fat, it's characterized by an approach
that also improves sagging.


Especially when the tissues under the chin descend,
emphasizing that area, lifting with threads can be helpful.
During the consultation, we assess the amount of fat under the chin, skin elasticity,
and jawline structure together.
After comprehensively evaluating these factors, we determine if thread lifting
is suitable.
Key Aspects in Double Chin Thread Lifting Consultations
Sagging under the chin is often caused by multiple factors
acting together rather than a single cause.

Therefore, during consultation, we check fat volume, skin elasticity,
and jawline structure together.
In some cases, fat reduction may be needed first, while in others,
thread lifting might be more appropriate for refining the line.
Sometimes, both approaches are considered together.

Costs and effects can also vary depending on the individual's condition.
In consultations, we prioritize identifying these structural factors first
and finding a direction that naturally refines the jawline.

Frequently Asked Questions
Why does a double chin form?
A double chin results from a complex interplay of factors including fat accumulation, reduced skin elasticity, jaw structure, and even smartphone usage habits. It's not just a matter of weight, but can involve various structural causes.
What are the main causes of a sagging jawline?
The main causes of a sagging jawline are reduced skin elasticity with age, increased fat under the chin, and weakening of the tissues that support the jaw. A short or recessed chin structure can also contribute.
Can thread lifting help improve a double chin?
Yes, thread lifting can be considered when sagging under the chin is prominent due to reduced skin elasticity. Thread lifting helps to support the sagging tissues upwards, refining the jawline and improving the appearance of sagging.
What aspects are checked during a thread lifting consultation?
During a consultation, we comprehensively assess the amount of fat under the chin, skin elasticity, and jawline structure. Based on these factors, we determine if thread lifting is suitable or if a different approach is needed.
Do lifestyle habits affect a double chin?
Yes, lifestyle habits can influence the formation of a double chin. Specifically, prolonged periods of looking down at a smartphone can cause the tissues under the chin to stretch, contributing to sagging.
Is there only one method for double chin improvement?
No, there isn't just one method for improving a double chin. Depending on the individual's condition, fat reduction might be primarily needed, or thread lifting might be more suitable for refining the jawline. In some cases, both approaches may be considered together.
