Double chin surgery in Sinsa

Hello. This is Ruo Plastic Surgery.

‘I didn’t gain weight, but I have only chin fat.’

‘When I take photos, my face looks round.’

‘My double chin doesn’t go away even when I exercise.’

When consulting with patients, there were many complaints about the face and

jawline.

This is a phenomenon that is difficult to explain simply by saying,

‘You gained weight.’

Even if your weight has not increased,

if you see a collapsed jawline and a round face,

you may consider double chin surgery.

In this post,

we will take a close look at various aspects such as

the causes of a double chin and the treatment process.

Small changes that disrupt the facial line

A state in which the skin and fat layer under the chin appear layered or sagging is called a 'double chin.'

In other words, the boundary between the jaw and neck becomes blurred,

changing into a shape that looks like there is

'one more layer of flesh' under the chin.

It occurs due to a combination of factors such as weight gain,

decreased skin elasticity,

muscle weakness, redistribution of facial fat, and posture problems.

Especially after your 30s, as collagen decreases due to aging,

the skin loses its ability to maintain elasticity on its own,

making the area under the chin prone to sagging.

As a result, the face appears larger,

and because of the heavier impression,

you may also look older.

Understanding the causes

The representative causes of a double chin,

which are created by a combination of lifestyle habits and aging,

can be defined as follows.

First, decreased elasticity due to aging

Collagen and elastin are key structures that support the skin,

and when they decrease, the skin under the chin stretches downward due to gravity.

Second, weight gain and fat accumulation

When weight increases, fat accumulates under the chin,

and the skin expands, developing into a double chin.

It is difficult to improve with exercise or dieting.

Third, poor posture

Holding the neck forward for long periods or leaning the head forward

makes the muscles under the chin loose and causes fat to sag.

It is also a cause of double chins in younger people.

Fourth, redistribution of facial fat

After your 30s, fat does not simply decrease;

it changes into a pattern of moving from the upper face to the lower face.

The cheekbone and cheek area lose volume, while the area under the chin sags.

Fifth, reduced lymphatic circulation and swelling

Poor lymph flow causes waste products and fluid to stagnate under the chin,

creating swelling.

At this time, the area under the chin appears puffy and looks as if you gained weight,

and over time, elasticity decreases and it develops into a double chin.

A double chin that appears due to these complex causes

is something that some people need a procedure or

surgery for.

You can remove it only by identifying the underlying cause that differs for each person

and performing customized surgery.

Is it for everyone?

🤔 If you lost weight but still have chin fat

'Although my weight went down, my face is still the same.'

In this type, the fat under the chin is thinly spread,

so it does not come off easily with exercise or weight loss.

🤔 A collapsed jawline and a dull-looking face

If the boundary between the neck and jaw is blurred and the face looks bigger,

it is a typical sign of aging.

🤔 If swelling or circulation problems cause the chin to swell

If the area under the chin frequently swells regardless of weight,

and your face looks heavy when you are tired,

this is a lymphatic circulation stagnation-type double chin.

If it cannot be resolved with exercise or massage,

or if the jawline keeps becoming less defined,

a professional approach is needed.

However, it is not necessary for everyone, so

it is recommended for the above types.

Conclusion

Double chin surgery in Sinsa

Our body and facial fat are not structured in a way that allows

fat to be selectively lost or gained only in the desired area.

Even if you exercise a lot and the fat remains or does not seem to go away much,

the face can look longer and leave an impression that lacks vitality.

Do not forget that a double chin occurs due to different factors such as

the skin, fat, and muscles under the chin,

depending on the person.

Meet medical staff who perform anatomical customized design tailored to each individual

and create a slimmer jawline.
