Yeongdeungpo Onda Lifting,

Is it effective for a double chin and under-chin fat?

"My weight is the same,

but it feels like the fat under my chin keeps sagging."

"Exercise or dieting doesn’t seem to

get rid of a double chin easily.

Can a procedure help?"

A double chin is not something that only

appears because of weight gain.

As people age, the skin under the chin can sag,

or the skin can loosen as collagen decreases.

These changes are not easy to resolve with

exercise or dieting.

That is because it is not only a problem of fat,

but also one where the skin itself has loosened.

Many people who are worried about a double chin

and under-chin fat look into Onda Lifting.

Today, let’s look at how Onda Lifting works

for a double chin and sagging under-chin fat,

and how effective it actually is.

  1. What is the real cause of sagging under-chin fat?

Yeongdeungpo Onda Lifting

The reasons under-chin fat sags

can largely be divided into two types.

One is subcutaneous fat.

The area under the chin is a place where fat tends to accumulate.

Once under-chin fat settles in,

it is not easily reduced even with exercise or dieting.

That is because fat cells in this area

are slower to decrease compared with other parts of the face.

Another reason is sagging skin caused by a decrease

in collagen in the dermis.

As we get older, collagen fibers in the dermis

become looser and their amount decreases.

Then the skin can no longer support the fat well

and begins to droop downward.

Among people whose double chin does not go away easily,

these two factors often progress together.

If only the fat is reduced, the skin may still remain loose.

If only the skin is tightened, the fat remains,

making it hard to feel a noticeable effect.

So when choosing a double chin procedure,

it is important to check whether it can act on both

fat and skin.

  1. How does Yeongdeungpo

Onda Lifting work?

Onda Lifting is a procedure that uses

2.45GHz microwaves.

Microwaves vibrate the water in the skin,

creating heat inside it.

The two handpieces in Onda Lifting

are each used for different purposes.

First, the 7mm handpiece

targets the fat layer.

It selectively heats subcutaneous fat,

causing it to naturally break down and decrease.

The 3mm handpiece targets the dermis,

causing existing collagen fibers to contract

and then encouraging new collagen production.

In other words, Onda Lifting can create two changes:

reducing fat and making the skin firmer again.

It is a procedure that can address the two causes

of a double chin mentioned earlier.

There is a clinical study on this effect,

so let’s take a look.

This data evaluated changes 12 weeks after the final treatment

in 10 women with moderate to severe submental sagging,

with an average age of 56,

after two Onda Lifting sessions performed

at 30-day intervals.

A double chin that appears in the 50s

often needs both fat reduction and lifting of sagging skin.

Then let’s look at the appearance before treatment

and after two sessions.

On the left, before treatment, the area under the chin was sagging,

which weakened the jawline and blurred the boundary

between the neck and the chin.

On the right, after treatment,

the sagging under the chin had improved

and the jawline looked more defined.

The researchers reported that the SMSLG

(submental sagging grade, out of 4 points)

improved from an average of 3.6 before treatment

to 2.3 at 12 weeks.

The more severe the sagging,

the greater the degree of change.

  1. Is one treatment enough, and how long does it last?

Yeongdeungpo Onda Lifting

If you are looking into the procedure,

you may also wonder about the number of sessions

and how long the results last.

In fact, this depends on each person’s condition.

Still, based on clinical research,

the study performed two sessions at 30-day intervals.

For people with mild sagging, even one session

may show a clear change,

but in cases like the study subjects,

where sagging was moderate or worse or there was more fat,

more than two sessions may be needed to see an effect.

Also, in the study, the effect was confirmed

to remain at 12 weeks after the final treatment.

Once collagen is created,

it tends to stay in place for a relatively long time,

but newly formed collagen also naturally decreases over time.

So to maintain the initial changes,

it is good to receive maintenance treatments

at regular intervals.

In general, intervals of 6 months to 1 year are recommended,

but the maintenance period can vary depending on

sun exposure and lifestyle habits.

Yeongdeungpo Onda Lifting is an effective procedure

because it acts simultaneously on both

fat and skin sagging, the two causes of a double chin

and sagging under-chin fat.

That is because it can address changes that were

not resolved by exercise or dieting.

However, all changes may not be completed

with just one treatment.

You can see the effect only by receiving as many

treatments as your skin condition requires.

So if you are considering the procedure,

please first check whether the fat under your chin

is the main issue or whether skin sagging is more noticeable.

Thank you. This was U&I Yeongdeungpo.^^
