a clinic that pursues the most beautiful feeling.

When it comes to radiofrequency lifting, the first treatment that comes to mind is Thermage.

But did you know that not all Thermage treatments are the same?

Hongdae Thermage laser has developed from the first generation

to the current fourth-generation FLX.

Thermage laser effect duration?

Thermage laser is a premium lifting treatment that uses radiofrequency (RF) technology

to deliver heat energy to the dermis layer,

induce collagen production,

and improve skin elasticity.

✔ Those with thin skin and concerns about fine lines

✔ Those whose skin texture has become dull due to aging

✔ Those who need overall skin tightening and lifting effects

👉 Recommended for people like this!

The effects appear gradually starting about 2 to 3 months after the procedure,

and last for about 1 year.

Temporary swelling or redness may occur,

but it usually recovers quickly and does not interfere with daily life.

Frequently asked question!

Q1. Are there still clinics using first- or second-generation Thermage?

There are still some directors who prefer the first and second generations.

Due to differences in preference for the treatment method,

there are cases where opinions about the effect differ even with sedation anesthesia,

and

in cases where refill cartridges, that is, non-genuine

refurbished tips are used,

so it is recommended that you carefully consider the first and second cases

when choosing a clinic.

Q2. Is a larger tip size always an advantage?

As the tip area becomes wider, the director’s technique becomes important.

What if there is little fat, many contours, and thin skin?

Because total-area contact is more difficult than expected,

there may instead be concerns about the risk of burns.

However, as technology has advanced,

safety has also increased,

so if you receive the treatment from a director who performs it carefully,

there is no need to worry too much!

Conclusion! Which Thermage should you choose?

Latest technology & fast procedure + precise energy control

Worried about side effects caused by refurbished tips?

→ FLX (4th generation) recommended!

✔ Choosing according to skin condition and budget is important!

It is important to receive the procedure at a trustworthy clinic!

Today, we explained the treatment effects of Hongdae Thermage laser

and the differences between each generation.

Since Thermage tips are single-use and the equipment is expensive,

using genuine tips is essential.

We recommend receiving the procedure at a reliable clinic

where you can confirm the use of genuine tips.

📌 At Jfeel Clinic, we use genuine Thermage equipment,

and provide customized treatments according to skin type.
