Hello.

This is Lim Jin-young,

Chief Director of Piaf Clinic.

Among the names that come to mind when you think of “lifting,”

Ulthera is definitely one of them.

However,

many people do not really know

exactly what Ulthera is,

or how it differs from other lifting treatments.

But it can be hard to choose

simply because it is famous,

or because people around you say it is good,

without a clear understanding.

So today,

I’m going to systematically explain

what the principles behind Sinnae-dong Ulthera are,

what effects you can actually expect,

and what you should know

in order to get proper results.

If you read this article to the end,

your questions about Ulthera

will be clearly answered.

Let’s begin.

Sinnae-dong Ulthera,

shall we start with the principles?

Ulthera is a lifting device that

uses ultrasound energy.

It delivers energy not to the skin surface,

but deep within the skin,

and works by tightening tissue

that has lost elasticity.

The key layer here is the

“SMAS layer.”

The SMAS layer is a thin membrane-like structure

located between the skin and the muscles,

and it acts as a kind of support base

that holds up the entire face.

As we age, when this layer

becomes loose and starts to sag downward,

the cheeks lose their shape,

the jawline becomes blurred,

and the face as a whole can look tired.

Sinnae-dong Ulthera reaches

this SMAS layer directly,

applies thermal stimulation

with ultrasound energy,

and contracts loosened tissue,

while inducing a collagen

regeneration response in the process.

This is how elasticity is restored

from deep within the skin.

Another strength of Ulthera is that

it is equipped with an ultrasound imaging device.

The practitioner can check the skin’s internal structure

in real time and adjust the location and depth

where the energy is delivered.

Thanks to this, more precise

and stable treatment is possible.

The required depth differs

depending on the degree of sagging,

and skin thickness varies greatly

by area, so this kind of customized adjustment

is extremely important.

In the end, Ulthera is not just about pulling

the skin that is visible on the outside,

but about correcting the structure

that supports the face itself,

and creating a natural, defined lifting effect.

Sinnae-dong Ulthera,

is the effect really good?

So then, what kind of changes

can you actually feel?

The first thing you’ll notice is

a more defined jawline.

The facial contour that had looked vague and sagging

will begin to gradually become more distinct

from right after the procedure.

The skin that had been sagging under the cheeks

is also lifted upward,

making the entire face look

a little more tightened and refined.

In many cases, the double chin

and the line around the neck

also improve.

In particular, people whose skin itself is thin

or has lost a lot of elasticity

may notice these changes more quickly.

However, Ulthera’s effects

do not appear all at once;

they tend to emerge gradually over time.

You may feel a slight immediate lifting effect

right after the procedure,

but the real changes are completed gradually

over the course of 2 to 3 months.

That is because the processes of

collagen regeneration and tissue reorganization

take time.

So when you look in the mirror a month later,

then two months later,

you may think,

“Hmm? Something looks different.”

The duration of the effect varies from person to person,

but it is generally known to last about

1 year to 1.5 years.

After that, depending on your skin condition,

additional treatments can be considered.

However, please remember that all of these effects

can only be expected when the right amount of energy

is delivered to the correct location.

Not for everyone

“Ulthera is good, so can’t I just get it done?”

It’s easy to think that way,

but in fact, lifting is an area that requires

far more of a personalized approach

than you might expect.

Everyone’s skin thickness,

elasticity, direction of sagging,

fat distribution, and muscle mass are different.

Even at the same age,

some people may have severe cheek sagging,

while others may only have

a weakened jawline.

Some people may have reduced elasticity

throughout the entire face,

while others may need focused care

only in specific areas.

In addition, lifestyle patterns

are also important.

Whether you can secure enough recovery time

after the procedure, how sensitive you are to pain,

whether you have had previous procedures,

and so on.

All of these conditions must be considered

in order to choose the lifting method

that is truly right for you.

So Sinnae-dong Ulthera

may not be the best choice for everyone.

In some cases, a radiofrequency method

may be more suitable,

and in others, combining two methods

may produce better results.

For example, if the skin is thin and sensitive,

the energy intensity must be adjusted delicately,

and if the fat layer is thick,

a setting that can stimulate deeper layers is needed.

Such judgments are impossible

without an accurate understanding of the skin condition.

So rather than simply thinking,

“It’s a famous procedure,”

it is much wiser to approach it by asking,

“Is this a procedure that suits my skin?”

So far,

I have explained the principles and expected effects

of Sinnae-dong Ulthera,

and why a personalized approach

is important for each individual.

To summarize the key points:

First, Ulthera uses ultrasound energy

to reach the SMAS layer,

contracting loosened tissue and inducing

collagen regeneration.

Second, you can expect gradual and natural changes

across the overall facial contour,

including jawline definition,

cheek lifting, and improvement of a double chin.

Third, since skin condition and lifestyle

are all different,

you should carefully judge whether

it is the right method for you.

Lifting is not something to decide

based only on the name of the device.

Understanding your skin properly

and finding the method that suits it

is the surest path to satisfying results.
