Seoul Ultherapy Results: When Can You Feel the Effect? image 1

Hello.

I’m Beauty Doctors Kim Jang-ju, and I design treatments not simply to “pull” the face,

but to first determine where and how to lift it so the result looks natural.

If you are considering a lifting procedure,

you’ve probably heard the name Ultherapy at least once.

Recently, this Ultherapy has been upgraded to a more refined version,

Ultherapy Prime.

Today, based on the questions I receive most often in the clinic,

I’ll calmly explain:

🌈 How Ultherapy works 🌈 The difference between the original Ultherapy and Prime 🌈 Who it may be a meaningful choice for

1️⃣ Ultherapy does not treat the “surface” of the skin

It works on the structure

Many people think of Ultherapy

as just a laser lifting treatment.

But its real target is the SMAS layer,

the deepest support structure of the skin.

This is the very structure directly pulled during facelift surgery,

and it is a key area where sagging begins with aging.

Ultherapy delivers high-intensity focused ultrasound (HIFU)

precisely to this depth, creating tiny thermal coagulation points.

As a result,

🌈 the tissue contracts immediately, 🌈 and during the recovery process, 🌈 new collagen is produced,

bringing firmness back from within the skin.

Even if there is not much visible change on the surface,

structural reorganization is starting inside the skin.

2️⃣ Why does it feel tight right away?

Changes after Ultherapy are usually divided into two stages.

🌈 Immediately after the procedure

Immediate response stage

When the protein structure exposed to heat is stimulated,

it contracts momentarily, creating a slight tightening sensation in the face.

🌈 After 1 to 3 months

Around the treated area,

collagen production and rearrangement progress,

and the jawline, cheeks, and contours gradually become more refined.

That is why Ultherapy is a treatment that best fits the saying,

“it gets better as time passes after the treatment.”

3️⃣ Do you have to endure the pain of Ultherapy?

When people think of Ultherapy,

they often first imagine a “tingling pain.”

This sensation occurs because the ultrasound energy

stimulates nerve pathways in the deeper layers.

However,

it is not a treatment where more pain means better results.

We use:

🌈 nerve block injection anesthesia 🌈 adjustment based on each person’s pain sensitivity 🌈 energy planning by treatment area

👉 to reduce unnecessary pain 👉 while accurately maintaining the necessary depth and energy.

Lifting should not be a treatment you simply endure;

it should be the result of careful planning.

4️⃣ Ultherapy is not a skin texture treatment

After Ultherapy,

some people feel that “there is not a big change in pores or skin texture.”

This is not a drawback, but a difference in role.

Ultherapy is

🌈 not a treatment that smooths the skin surface, 🌈 but a device specialized in structural lifting

that pulls sagging tissue upward.

To compare it with a house,

it is like the foundation work,

not wallpapering or finishing.

Seoul

Improvements in skin texture and tone

require combination with other treatments.

5️⃣ Areas where Ultherapy satisfaction is especially high

It can be applied to the entire face,

but the effect is especially noticeable in the following areas.

🌈 Sagging of the deep cheek area (bulldog cheeks) 🌈 The lower cheek area that causes deep nasolabial folds 🌈 The line collapsed below the lateral cheekbone area 🌈 Double chin, loose jawline

These areas are not a problem of insufficient volume,

but of structures shifting downward,

which is why Ultherapy’s strengths stand out well.

6️⃣ The key changes in Ultherapy Prime

The biggest change in Prime is

👉 DeepSEE™ ultrasound imaging,

which allows confirmation up to a depth of 8 mm.

Since everyone has different

🌈 fascia layer positions 🌈 fat thickness 🌈 skin structure

there is a clear limit to lifting without seeing the area first.

With real-time imaging,

Prime helps us

🌈 check where the energy is delivered, 🌈 avoid unnecessary areas, 🌈 and target only the necessary structures accurately.

7️⃣ Knowing safety is skill

Because Ultherapy is a powerful device,

it is important to know which areas should not be treated.

🌈 Avoiding the thyroid area in the center of the neck 🌈 Adjusting depth and angle in areas where hollowing is a concern 🌈 Designing treatment lines with blood vessels and nerve distribution in mind

Even with the same device,

the results and safety can differ greatly depending on who uses it and how.

8️⃣ Is Ultherapy a one-time treatment?

I compare Ultherapy to

“adding support lines.”

You can feel a change after just one session,

but aging continues.

Periodic treatments are closer to the concept of

reinforcing the overall structure by adding new support lines on top of the existing ones.

Rather than an excessive frequency,

setting intervals that match each person’s aging speed is important.

9️⃣ How to maximize the effect of Ultherapy

In clinical practice, the most satisfying cases are when

🌈 the areas to be lifted are reduced with Ultherapy, 🌈 and sunken areas are supplemented with filler or skin boosters.

For lifting,

it is not about “how much you fire,”

but about how and where you design it that determines the result.

Devices continue to evolve.

But what kind of face you create with that device,

and in what direction,

ultimately depends on the doctor’s judgment and experience.

If you want to find a clearer line

through the more advanced Ultherapy Prime,

while avoiding overdoing it,

please feel free to discuss it through a consultation.

If you have any questions,

please contact us anytime.

Thank you for reading.
