Mokdong Ulthera

Hello.

I am Kim Jin-hyeon, Chief Director of U&I Clinic Mokdong Branch.

“Could it cause hollow cheeks?”

“Isn’t it supposed to hurt a lot...

Won’t it leave bruises afterward?”

Ulthera is widely known as a lifting treatment with good results, but at the same time, it naturally raises a number of concerns.

So today, before an Ulthera procedure, I’ll go over the three questions people ask most often and explain them in detail so there are no misunderstandings.

Mokdong Ulthera

What kind of procedure is it?

Ulthera is a representative lifting procedure that uses ultrasound energy.

It works by delivering heat in a concentrated way to the deeper layers of the skin to induce collagen regeneration.

It is similar in principle to the ultrasound examinations commonly used in hospitals, but the difference is that Ulthera uses much stronger energy with the goal of achieving a lifting effect.

In this process, collagen and elastin inside the skin are stimulated and form new structures, which can help improve elasticity and produce a skin-lifting effect.

In particular, because it helps reactivate collagen that naturally decreases with age, it is suitable for people who want a natural and gradual lift.

Another major advantage of Ulthera is that the procedure can be performed while viewing real-time ultrasound images.

This allows the practitioner to directly check the skin structure and precisely deliver energy to the necessary depth and area, which can reduce tissue damage while improving results.

Recently, 'Ulthera Prime' (Ulthera Prime), which maintains the advantages of the existing Ulthera while allowing more delicate energy control, has been introduced and is drawing attention.

Ulthera Prime has improved DeepSEE technology compared with the existing device, giving it the advantage of allowing more precise visualization of the skin layers using ultrasound.

As a result, it can be used precisely even on thin and sensitive areas such as the cheeks and forehead.

Hollow cheeks

One of the biggest concerns for people before the procedure is hollow cheeks.

In fact, there are quite a few cases where people give up on the procedure after hearing stories that their cheeks became hollow after Ulthera.

However, this phenomenon is not so much a problem with Ulthera itself as something that can vary depending on the treatment method and the individual’s characteristics.

Ulthera temporarily contracts the skin tissue.

Because of this, right after the procedure, the volume may appear to decrease slightly.

This is similar to how a sponge becomes smaller when squeezed.

Over time, new collagen is produced and the volume generally recovers.

However, if the face originally has little cheek fat,

or if energy is used excessively beyond what is needed,

or if the procedure is performed on the wrong area without an understanding of anatomy, recovery may be delayed or hollow cheeks may occur.

To reduce these risks, it is most important to receive a personalized treatment from experienced medical staff who clearly understand facial structure.

Pain and bruising

Many people wonder before the procedure whether it hurts a lot or causes bruising.

First, regarding pain, Ulthera delivers strong ultrasound energy to the deep layers of the skin, so you may feel a brief sharp or tingling sensation.

In particular, areas with thin skin or heightened sensitivity may feel pain more strongly.

However, for people who are sensitive to pain, a sufficient amount of numbing cream is applied in advance, and the procedure is carried out while communicating with the medical staff in real time, so there is no need to worry too much.

And regarding bruising, Ulthera is relatively unlikely to cause bruising because of the nature of the procedure.

Unlike lasers or injections, it does not directly penetrate the skin or stimulate blood vessels, so bruising is rare. Even when it does occur, it is usually short-lived and localized.

Immediately after the procedure, there may be swelling or a slight feeling of tightness, but this naturally subsides within a few hours to a few days.

However, do not massage the area forcefully just because it feels uncomfortable, and avoiding intense exercise or a sauna on the day of the procedure will help recovery.

In conclusion, Ulthera is a procedure with a relatively low burden in terms of pain and bruising, and if you prepare appropriately and receive the treatment according to the medical staff’s guidance, most people can experience a comfortable recovery.

Today, I have summarized the information that people considering Mokdong Ulthera are likely to be curious about.

Among non-surgical lifting procedures, Ulthera is well regarded in terms of precision and effectiveness.

However, it is not a procedure that is equally good for everyone.

Because factors such as skin elasticity, fat distribution, and bone structure all interact in complex ways, a diagnosis suited to your own facial condition must come first.

This has been Kim Jin-hyeon, Chief Director of U&I Clinic Mokdong Branch.

Thank you.
