When you look in the mirror, have you ever noticed that your skin no longer has the same

firmness as before, along with increasing wrinkles?

Even in a busy daily life, many people think, “Surgery feels like too much of a burden,

but it would be a pity to simply leave skin aging alone.”

Today, from the perspective of a dermatology specialist, we will provide a detailed guide to the

Thermage FLX procedure offered at Human Dermatology Seoul National University Branch!

Why Thermage FLX?

Thermage FLX is a premium radiofrequency lifting laser developed by Solta Medical in the United States.

It works by delivering radiofrequency energy into the dermal layer of the skin,

causing existing collagen to contract and promoting the production of new collagen. Through this process,

you can achieve both wrinkle improvement and enhanced skin elasticity at the same time,

and because it is a non-surgical procedure without incisions,

it is safe and recovery is quick!

Key Features of Thermage FLX!

  • Precise energy delivery: With AccuREP™ technology,

each shot delivers radiofrequency energy consistently and safely.

  • Powerful lifting and wrinkle improvement: It effectively improves everything from deep wrinkles

to fine lines.

  • Fast procedure and less pain: The vibration handpiece and cooling system reduce pain

and shorten the procedure time.

  • Quick return to daily life: Because there is no incision,

you can resume daily activities immediately after the procedure.

With these many advantages, Thermage FLX is preferred by many people not only for lifting, but also because it allows them to enjoy the benefits while minimizing inconvenience in daily life. So, for whom would this procedure be a good choice?

Thermage FLX is recommended for people like this!

  • Those whose face looks saggy due to reduced skin elasticity

  • Those who need lifting for the entire face, such as the cheeks, jawline, and eye area

  • Those who want improvement in fine lines and deep wrinkles

  • Those who want quick results instead of surgery

When you actually receive a consultation, many people say, “Surgery feels burdensome, and I want to improve naturally.”

In exactly these cases, Thermage FLX can be a good alternative :)

In this way, Thermage FLX can provide both immediate tightening effects and long-term collagen regeneration

effects with just one treatment. But how is it different from “Ulthera,” another similar lifting procedure?

What is the difference from Ulthera?

Thermage FLX: Radiofrequency acts on the dermal layer (about 3 mm)

→ Strong for wrinkle improvement, skin texture, and pore refinement

Ulthera: Ultrasound acts on the SMAS layer (about 4.5 mm)

→ Specialized for skin lifting and contour improvement

➡ Because the two procedures work differently,

combining them can create an even greater synergy effect.

Since these two procedures act on different layers and have different effects, they can be selected or combined

depending on the patient’s skin condition and desired results. So what specific skin improvement effects can you expect

from Thermage FLX?

Expected improvement effects

Immediate lifting and improved elasticity

Wrinkle reduction through collagen regeneration

Improved skin texture and reduced pore size

Brighter skin tone and reduced dullness

Long-term and gradual lifting effects

Not only wrinkle improvement, but also overall improvement in skin texture, pores, and skin tone

makes it fair to call this a “total anti-aging procedure” :)

Frequently Asked Questions (FAQ)

Q1. Is the Thermage FLX procedure painful?

A. Compared with older-generation Thermage, FLX has introduced a vibration handpiece and cooling system,

which has greatly reduced pain. Although it varies by person, most people find it tolerable,

and if necessary, a numbing cream can be used to relieve pain.

Q2. When do the effects start to appear?

A. A tightening sensation can be felt immediately after the procedure,

and collagen regeneration effects begin to activate in earnest after about 2 weeks. However, there may be individual differences,

so we recommend visiting the clinic for a detailed consultation.

Q3. What is the difference between Thermage FLX and Ulthera?

A. Thermage uses radiofrequency to act on the dermal layer (3 mm),

making it strong for improving wrinkles, elasticity, and skin texture, while Ulthera uses ultrasound to act on the SMAS layer (4.5 mm),

specializing in lifting and contour improvement. When used together, the two procedures create an even greater

synergy effect.

Q4. Can I return to daily life immediately after the procedure?

A. Yes. Because it is a non-invasive procedure without incisions,

a recovery period is not needed, and most people can return to daily life immediately after the procedure.

However, for a few days after the procedure, it is best to avoid excessive heat exposure (saunas, jjimjilbang, etc.).

Q5. How many sessions are needed?

A. One of the advantages of Thermage FLX is that its effects can last for a long time even after just one session.

Although it varies depending on the individual skin condition, repeating the procedure about once or twice a year is usually recommended.
