“People get Ulthera a lot...

I’m worried about the pain.

Could side effects like hollow cheeks also happen?”

I hear questions like this in the consultation room several times a day.

In fact, many people considering the procedure say things like, “The effect is good, but I’m worried about the pain,” or “I’m scared my face might look sunken.”

Ulthera is one of the lifting devices with strong energy, so depending on how it is used, it can produce good results, but side effects such as hollow cheeks can also appear.

Today, to ease some of that concern, I’d like to explain the principle behind Ulthera, how to prevent side effects, and the criteria for receiving it safely in an easy-to-understand way.

  • The principle of Ulthera

  • Side effects and hollow cheeks: can they really be avoided?

  • Pain and recovery: the “perceived difficulty” that real patients talk about

The Principle of Ulthera

Ulthera is a procedure that delivers high-intensity focused ultrasound energy (HIFU) to the deep SMAS layer of the skin, that is, the firm membrane that surrounds the facial muscles, to restore elasticity.

When the ultrasound energy reaches the tissue, microscopic thermal coagulation points of 60 to 70 degrees Celsius are created, tightening the tissue and stimulating new collagen and elastin production.

In other words, the skin recovers on its own and regains elasticity.

That is why the face may look lifted immediately after an Ulthera procedure, but the real effect begins to appear in earnest after 2 to 3 months, when collagen regeneration takes place.

During the Ulthera procedure, the thickness of the skin and fat layer is checked directly with ultrasound imaging, and the depth and intensity of the energy are adjusted accordingly.

So in thinner areas of the skin, it is applied more gently, while in areas that need firmness, such as the jawline, the energy is delivered a little more strongly.

The energy intensity must be adjusted differently for each patient in order to achieve uniform lifting without side effects.

Recently, the latest device, Ultherapy Prime, has been widely used.

This device has higher image resolution than the existing Ulthera and is designed so that the ultrasound energy spreads much more evenly.

Thanks to that, it is possible to deliver energy more safely while checking the structures inside the skin more clearly.

Many patients who have undergone the procedure also say that the pain is much less than before and that skin irritation has decreased, making them more satisfied.

Because the effect is maintained at the same level as existing Ulthera, you can expect a comfortable yet firm lifting result.

Side Effects and Hollow Cheeks,

Can They Really Be Avoided?

The keyword many people worry about most while searching is “Sinchon Ulthera side effects.”

A representative example is hollow cheeks (sunken cheeks).

In fact, this is not a problem with the device itself, but mostly a problem with the procedure design and energy adjustment.

The face is not a structure that simply lifts in one direction.

For people with little cheek fat, if the heat goes too deep, the fat may decrease and make the area look sunken.

In areas that need firmness, such as the jawline, enough energy must be applied for the effect to appear.

That is why before the procedure, I consider the thickness of the fat layer, the direction of the muscles, and the thickness of the skin all together and design where to avoid and where to focus.

“I already have a somewhat sunken face—can I still get Ulthera?” I get this question often as well.

In those cases, the ultrasound depth is adjusted to avoid the area, or in some cases, a radiofrequency lifting procedure such as Thermage is performed together.

In the end, the key to Ulthera is not the machine, but the subtle skill of hands that understand facial structure.

Pain and Recovery,

The “Perceived Difficulty” That Real Patients Talk About

If You’re Hesitating Because Ulthera in Sinchon Works Well but You’re Worried It Might Hurt image 5

In truth, pain varies greatly from person to person.

However, in areas where the skin is thin or close to bone (for example, the cheekbones or the tip of the chin), you may feel a momentary dull heat sensation.

But recently, this has improved a lot.

Ultherapy Prime is designed with a gentler energy dispersion method than the existing device, so the heat does not concentrate in one place and is delivered evenly.

Thanks to that, sharp pain has been greatly reduced.

Before the procedure, anesthetic cream is applied sufficiently to reduce skin sensation,

and during the procedure, the energy is adjusted while monitoring the patient’s response.

Thanks to that, even people with sensitive skin usually say, “It’s more tolerable than I expected.”

After the procedure, there may be mild swelling or a feeling of heat, but it usually disappears within a day or two, and you can return to daily life right away.

If You’re Considering Ulthera in Sinchon, Keep These Three Things in Mind.

  1. Designing according to facial structure is the most important thing.

The depth and direction of the energy are determined by the medical provider’s experience.

  1. Pain can be managed.

When the latest device, Ultherapy Prime, is used, energy is delivered evenly, reducing pain while naturally maintaining the effect.

  1. The effect appears slowly, but clearly.

After 2 to 3 months, collagen regenerates and natural firmness returns.

Ulthera is a procedure that can restore facial contours without surgery.

Through accurate understanding and customized design, I hope it becomes an experience where satisfaction is greater than concern.
