Even after dieting or losing weight,
a double chin may not disappear easily.

This is because a double chin

is not always caused by submental fat alone.


Reduced skin elasticity, sagging tissues,

changes in the fascial layer, and facial structure may all contribute.

Therefore, when considering double chin treatment,
it is more important to identify why your jawline has become less defined
than to simply choose the most well-known procedure.

If excess fat is the main concern, fat reduction may be considered.
If skin and tissue laxity are more noticeable,

lifting treatment may be appropriate.

When reduced skin elasticity is also present,
combining treatment with skin-tightening care may help create

a more natural and defined jawline.

In this article, we will look at when APTOS thread lifting,
GU Clinic’s SCOOP Injection, and Thermage may be suitable options

for double chin treatment.


"Why Does a Double Chin

Remain Even After Weight Loss?"

A double chin is often thought to develop simply

because of weight gain or fat accumulation beneath the chin.

However, some people notice heaviness under the chin
or a less defined facial contour even

without significant changes in weight.

Common causes of a double chin include:

  • Localized fat beneath the chin

  • Reduced skin elasticity

  • Sagging skin and tissues

  • Changes in the fascial layer

  • Structural characteristics of the chin and face

  • Age-related changes in facial contours

Although double chins may appear similar,
the contributing factors can vary from person to person.

If the underlying cause is not properly identified
and the same treatment is applied to everyone,
it may be difficult to achieve the expected improvement.


"Double Chin Treatments

Differ Depending on the Cause"

The most appropriate approach depends on
which factor is contributing most to the double chin.

Main Concern

Treatment Option to Consider

Thick submental fat

SCOOP Injection for localized fat reduction

Blurred jawline caused

by tissue sagging

APTOS thread lifting

Reduced skin elasticity

Thermage for skin tightening

A combination of fat, sagging,

and laxity

A customized combination treatment

A single treatment cannot be applied

in the same way to every double chin.

It is important to distinguish between fat,

skin laxity, and sagging tissues, and then select

or combine treatments accordingly.


"When Is

APTOS Thread Lifting Suitable?"

APTOS thread lifting is a bio-thread lifting procedure
that supports sagging tissues in a targeted direction
to help refine the facial contour.

It may be considered in the following cases

  • When the jawline appears blurred due to downward skin and tissue sagging

  • When the facial contour looks less defined or has begun to collapse

  • When reduced skin elasticity and tissue sagging are both present

  • When sagging, rather than excess fat, is the main cause of the double chin

APTOS thread lifting focuses on supporting sagging tissues
and refining the jawline.

It may therefore be helpful when a double chin appears

more prominent because of skin and tissue laxity.

However, it does not directly reduce fat.
If there is a significant amount of fat beneath the chin,
combining it with another treatment may be beneficial.

"When Is

GU Clinic’s SCOOP Injection Suitable?"

GU Clinic’s Scoop Injection is a fat-dissolving injection
developed through an independent process by the medical director
and is used to target localized fat.

It may help thin the subcutaneous fat layer
by supporting fat cell breakdown and lymphatic circulation.

It is also a steroid-free fat-dissolving injection.

SCOOP Injection may be considered in the following cases:

  • When submental fat remains despite exercise or dietary changes

  • When the subcutaneous fat layer beneath the chin is thick

  • When facial contours appear heavy or less defined because of fat

  • When a slimmer and more refined jawline is desired

However, if skin elasticity is significantly reduced,
removing fat alone may make the skin appear looser.

In such cases, skin-tightening treatment or lifting may also need to be considered.

"Who Is

Thermage Recommended For?"

Thermage is a treatment that uses radiofrequency energy
to help improve skin elasticity.

It may be used when reduced skin elasticity is the main cause of a double chin
or when the skin needs additional firming after a fat-reduction treatment.

Thermage may be suitable in the following cases:

  • When the jawline appears less defined because of reduced skin elasticity

  • When the skin beneath the chin looks loose

  • When skin firmness needs to be improved after fat reduction

  • When gradual tightening is preferred over immediate tissue repositioning

Thermage stimulates collagen remodeling within the skin,
helping the skin gradually appear firmer over time.

However, if there is a significant amount of submental fat,
Thermage alone may not sufficiently address the fat-related concern.

In this case, it is important to determine whether another treatment

should be combined based on the condition of the area beneath the chin.

"Why Are Multiple Double Chin Treatments

Sometimes Combined?"

In many cases, a double chin is caused by several factors

at the same time rather than by fat or sagging alone.

For example, if excess submental fat is accompanied by reduced skin elasticity,
combining fat reduction with skin-tightening treatment may be helpful.

If sagging tissues are also present,
thread lifting may be added to help refine the facial contour.

APTOS thread lifting, SCOOP Injection,

and Thermage do not serve the same purpose.

  • APTOS thread lifting: Supports sagging tissues and refines the facial contour

  • SCOOP Injection: Targets localized fat beneath the chin

  • Thermage: Improves skin elasticity

Because each treatment addresses a different concern,
the treatment plan should be designed according to the specific needs of the individual.


"What Does GU Clinic Assess First?"

When considering double chin treatment in Gangnam,
it is more important to identify the cause of the double chin
than to choose a device simply because it is well known.

  • Amount of submental fat

  • Skin elasticity

  • Degree of tissue sagging

  • Facial structure

Based on these findings, we determine whether fat reduction,

lifting, or skin tightening should be prioritized
and whether a combination treatment may be appropriate.


"Frequently Asked Questions

About Double Chin Treatment"

Q1. Can weight loss eliminate a double chin?

If submental fat is the main cause, weight loss may lead to some improvement.

However, if reduced skin elasticity, tissue sagging, or facial structure also contribute,
significant improvement may be difficult to achieve through weight loss alone.

Q2. What is the best treatment for a double chin?

The same treatment cannot be applied to everyone.

For this reason, it is difficult to name one treatment

as the best option for all patients.

Q3. Can multiple treatments be performed together?

If fat, reduced skin elasticity, and tissue sagging are all present,
two or more treatments may be combined depending on the individual condition.

The appropriate treatments and order of procedures may vary from person to person,
so a thorough consultation is necessary.


A double chin may look similar from the outside,
but the underlying causes can differ depending on the individual,
including fat, reduced skin elasticity,

sagging tissues, and facial structure.

At GU Clinic, we assess each patient

through a detailed consultation and facial analysis
to create an individualized double chin treatment plan in Gangnam.
