Hello.

When you start looking into lifting, you often run into one big question.

"Thermage, Oligio, InMode, Shringk, Ulthera, thread lifting... What am I actually supposed to get?"

There are many procedure names, but it can be hard to find a place that clearly explains how they actually work differently within your skin.

Because of that, people often end up choosing based only on reviews or comparing only prices.

But lifting procedures differ completely from device to device in terms of how deep the energy reaches and how it works.

Just as different instruments resonate in different ranges even if they are both instruments, radiofrequency and ultrasound

and thread lifting each play different roles within the skin.

Today, for those considering Yangcheon-gu lifting, I will explain how these three categories differ

and summarize them with evidence from actual research results.

Even if you do not choose us, if you understand these differences, it will help you choose the procedure that suits you no matter where you go. ^^

  1. Radiofrequency vs. Ultrasound, The layer of action and purpose are different

Yangcheon-gu lifting First, let’s look at radiofrequency (RF) lifting.

Radiofrequency uses heat to warm the collagen fibers in the dermis, causing them to contract,

and then induces the generation of new collagen.

In simple terms, it works by tightening the skin’s elastic network again, so you can think of it as being closer to “improving skin quality.”

Representative devices include Thermage FLX, Oligio, and InMode.

In particular, with InMode, you should definitely understand the difference between the Forma and FX modes.

Forma delivers radiofrequency heat evenly from the surface to the dermis

and is a firmness-focused procedure that ensures safety through real-time temperature monitoring.

By contrast, FX is a completely different concept.

It works by mechanically suctioning and fixing the skin like tweezers,

and then simultaneously delivering radiofrequency and high-voltage energy through that space.

The electroporation that occurs at this time coagulates and breaks down fat cells.

Beyond simple tightening, you can expect an effect that reduces cheek fat and even fat under the chin—literally a procedure that

“tightens while reducing.”

Then what about ultrasound (HIFU) lifting? Ultrasound delivers high-intensity focused energy to the SMAS layer, the fascia layer located deepest in the skin, and forms thermal coagulation points.

The SMAS layer is the very structure that is actually pulled in plastic surgery facelift operations.

If radiofrequency targets collagen in the dermis, ultrasound targets a much deeper depth of about 4.5 mm, so it is closer to “improving sagging.”

The representative device Shringk is cost-effective, so it is often used repeatedly and is suitable for maintenance care,

while Ultherapy Prime has high precision thanks to real-time imaging,

so you can expect a strong lifting effect even with a single session, but the pain and cost are relatively high.

  1. A comparison of radiofrequency vs. ultrasound seen through actual studies

Yangcheon-gu lifting "So which one is better?" Many people ask this, but the answer becomes clear when you look at actual study results.

Ultrasound tightening of facial and neck skin: a rater-blinded prospective cohort study

First, this is a clinical study published in 2011 on ultrasound alone.

In patients with moderate facial sagging, after HIFU treatment and 90 days of follow-up,

the eyebrows rose by an average of 1.7 mm, and tightening of the lower face and jawline improved significantly.

This demonstrates a structural lifting effect by forming thermal coagulation points all the way down to the SMAS layer.

A Randomized, Split-Face, Evaluator-Blind Clinical Trial Comparing Monopolar Radiofrequency

Versus Microfocused Ultrasound With Visualization

for Lifting and Tightening of the Face and Upper Neck.

And there is an even more interesting study.

It is a comparative study in which one side of the same patient’s face was treated with ultrasound and the other side with radiofrequency.

After 12 weeks of follow-up, the ultrasound side showed better jawline lifting effects,

while the radiofrequency side showed better skin elasticity and skin texture improvement.

Both procedures had high satisfaction, but the areas and methods of improvement were different.

In other words, the conclusion is not that one is better or worse, but that the indications are different.

  1. What is thread lifting?

Yangcheon-gu lifting If radiofrequency and ultrasound use energy, that is, “thermal stimulation,” to tighten the skin, thread lifting takes a completely different approach.

That is because medical absorbable threads are inserted directly under the skin without using a device,

physically pulling and lifting the tissue.

In particular, cog threads have small barbs on the surface, and these barbs hook into the subcutaneous tissue and pull it upward.

That is why the lifting effect is visible immediately after the procedure, which is its biggest feature.

In addition, as the body’s natural healing response occurs around the inserted threads and collagen synthesis is promoted,

the firmness improvement effect can be maintained for a certain period even after the threads are absorbed over several months.

However, compared with device-based procedures,

there is downtime such as swelling or a pulling sensation after the procedure,

and you should know that the practitioner’s skill has a major effect on the outcome.

These days, many cases use a combined approach of first securing structural lifting with thread lifting and then maintaining firmness with radiofrequency or ultrasound.

So far, for those considering Yangcheon-gu lifting, I have explained the working principles of radiofrequency, ultrasound, and thread lifting, the differences between devices, and actual research evidence.

The most important point is that the first step is not the device name, but an accurate diagnosis of your facial condition.

If you have any questions, I recommend getting a consultation comfortably, even if it is not with us.

Thank you for reading this long post.
