Jamsil Onda Lifting and Hollow Cheeks: Can People with Low Facial Fat Also Receive It?

Jamsil Onda Lifting and Hollow Cheeks,

Can people with low facial fat also receive it?

Hello.

This is U&i Clinic, Jamsil.

“​​I want to reduce my double chin,

but I’m worried that my cheeks might become hollow.

Can I receive Onda lifting

even if I have little facial fat?”

This is a question we often hear during consultations.

With Onda lifting, energy can be delivered selectively

to areas of facial fat.

Therefore, it is a treatment that can also be received

by people who have little facial fat.

However, areas with little fat should be avoided,

while treatment should focus on areas you want to reduce,

such as fat under the chin.

In particular, as people age,

fat in the front and side cheek areas

can decrease more easily.

Therefore, it is important to establish

a lifting plan for each area.

Today, we will look at how Onda lifting

works inside the skin

and how to determine the treatment approach

based on a study that focused on fat under the chin

while leaving the side cheeks untreated.

Areas with little fat and areas with more fat

The same face can have areas with little fat

and areas with more fat.

In particular, when localized fat accumulates under the chin,

the facial contour can look heavier

and its definition may appear less distinct.

On the other hand, if there is little fat in the front and side cheeks,

hollow cheeks can develop,

creating shadows on the face

and making the person look tired.

Also, when evaluating facial fat,

it is important to examine the face from multiple angles

rather than only from the front.

This is because even if the face looks thin from the front,

fat may still be present separately under the chin.

Conversely, what looks like a double chin

may be caused more by skin laxity, neck muscles,

or the position of the jaw than by fat.

Therefore, rather than simply determining whether the face has a lot or little fat,

it is first necessary to distinguish

which areas actually contain fat that should be reduced

and which areas are providing support through their volume.

If the front or side cheeks are already hollow

and the lower cheek fat is also thin,

there is no reason to treat a wide area

with the goal of reducing fat there as well.

If localized fat remains only under the chin,

the cheeks can be excluded from the treatment area,

with a treatment plan focused only on the area under the chin

and along the jawline.

How does Onda lifting work on the skin?

Onda lifting equipment at U&i Clinic, Jamsil

Onda uses 2.45 GHz microwaves.

When this energy is delivered to the tissue,

it causes a thermal reaction.

Depending on the handpiece used and the settings,

the target depth and treatment range vary.

Heat delivered to the fat layer

may induce changes in localized fat tissue,

while heat delivered to the dermis

helps improve firmness through collagen contraction

and reorganization.

Simply put, Onda lifting does not work

only through a mechanism that reduces fat.

Jamsil Onda lifting handpiece

If fat under the chin is a concern,

a handpiece that focuses on the fat layer

can be used.

If you only want to improve firmness,

a handpiece that focuses on the dermal layer

can be selected.

The areas that become reduced

and the impression of the facial contour

will vary depending on which handpiece is selected

and how much and how often each area is treated.

What does research show about reducing fat under the chin?

A study published in 2025

included 10 women with moderate to severe

submental skin laxity.

Research on Onda lifting

After two treatments given 30 days apart,

the participants were evaluated

until 12 weeks after the final treatment.

The submental skin laxity score

decreased from an average of 3.6 out of 4

to 2.3 at 12 weeks.

Changes in the submental skin laxity score

No adverse reactions were reported during the study period,

and the study recorded that pain and discomfort were also minimal.

Before-and-after photos of Onda lifting treatment

The before-and-after photos showed

that the area under the chin and the jawline

appeared more defined.

In the photos, there did not appear to be

additional hollowing in the side cheeks

or a visible reduction in cheek volume.

However, because the study did not measure that area separately,

this was something that could only be considered

based on observation.

How can you receive treatment without worrying about hollow cheeks?

To receive Onda lifting without worrying about hollow cheeks,

you should first determine where

and how much fat and laxity are present in your skin.

The actual thickness of the fat

should be assessed by gently grasping the tissue under the chin,

while existing hollowness visible when smiling

or closing the mouth should also be examined,

along with the front and side views.

Whether you have previously received a fat-reduction treatment,

whether you have recently lost weight quickly,

and whether there is a difference in volume between the two sides of the face

can also affect the treatment range.

Also, if you are concerned about hollow cheeks,

rather than treating aggressively with a high level of energy from the beginning,

one option is to assess the facial contour and skin response after the first session

and leave room to adjust the next treatment area and settings.

Therefore, we hope you will have a thorough consultation

about how to approach Jamsil Onda lifting

according to your individual skin condition.
