If you’re researching Thermage in South Korea or the Phoenix Radio Wave treatment in Seoul, have you also noticed that people often compare things like “how much does 600 shots cost?” and “what’s the maximum energy level?”

But in reality, what truly affects the treatment outcome isn’t just the number of sessions.

August 29, 2026,Solta Medical KoreaThe SOMA Thermage FLX Symposium was held in Seoul, with around 300 healthcare professionals in attendance. At the event, the clinical consensus on Thermage FLX, compiled by 16 highly experienced Dermatology specialists from South Korea, was also made publicly available.

There are a few key points that those planning to launch Phoenix Radio should know first.

In South Korea, it’s not true that the higher the energy for Thermage, the better.

The consensus reached this time indicates that the typical starting energy for facial Thermage is around 2.5–3.0, with adjustments made based on each individual’s skin condition and tolerance level.

So it’s not the case that “the higher the dose, the more effective it is.”

For those with thinner faces and less fat, as opposed to those with thicker mid- and lower faces that show obvious sagging, the procedure simply shouldn’t be carried out in exactly the same way.

Instead of constantly asking about the energy level, it’s more useful to ask:

How will the doctor adjust the treatment based on my face shape, areas of sagging, and reaction?

Aging in Asians isn’t necessarily just about “loose skin.”

This time, doctors from South Korea also specifically mentioned that the common aging patterns seen in Asians are not exactly the same as those in Westerners.

For many Asians, the issue isn’t simply fat loss, but rather a gradual downward shift of the midface fat pad, which leads to the appearance of:

The jawline becomes less defined, the flesh around the mouth and Nasolabial Fold Correction become more noticeable, or even though there aren’t many wrinkles, the entire face still appears to sag slightly.

This is also why it’s best to have a doctor determine first whether the issue is sagging, hollowing, or fat problems before undergoing Thermage, rather than deciding on the number of sessions on your own.

Extra care must be taken with Eye Thermage to ensure safety.

The thickness of the eyelids is only about 0.8–1.2 mm, so Thermage treatments around the eyes cannot be exactly the same as those for the rest of the face.

This safety guide specifically emphasizes that specialized Eye Tips and plastic ocular shields should be used during treatments around the eyes, while also paying attention to any sensations of heat or pain that may occur during the procedure.

If you’ve previously undergone LASIK, SMILE, or other eye surgeries, it’s also recommended to inform the doctor promptly during your in-person consultation.

DAN-A’s director, Lee In-jee, also participated in this expert panel discussion.

Dr. Eunji Lee, director of Dan-A Clinic, was once again invited to participate in the Talk Concert at the SOMA Thermage FLX Symposium, where she shared her practical clinical experience with numerous doctors from South Korea.

She mentioned that she places great emphasis on communicating with patients throughout the treatment process, constantly checking in on their feelings of heat, pain, and overall reactions. She describes this approach as “Verbal Massage.”

In other words, Thermage doesn’t just fire a few hundred shots and call it a day.

It’s just as important that the doctor continuously monitors and asks questions, adjusting accordingly to each person’s response.

It should be specifically noted that Director Lee Eun-jee participated in the professional panel discussion on that day, and was not one of the 16 doctors who reached a Delphi consensus as mentioned in the article.

If you’re thinking about getting Thermage treatment in South Korea, don’t just focus on the price first.

If you’re considering Phoenix Radio, ask yourself first:

Is my problem actually sagging, hollowing, or fat?

Am I a good candidate for Thermage, or do I actually need ultrasound or other treatments?

If you can’t make a decision on your own, there’s no need to decide on the treatment plan right away.

You can first send the front and 45-degree side photos, along with the area you’d like to improve the most, to the clinic, so the doctor can make a decision after an in-person consultation.

Frequently Asked Questions FAQ

Q: How many sessions of Thermage FLX are recommended at a time?

A: The number of injections isn’t fixed—it needs to be adjusted based on facial shape, fat thickness, and degree of sagging. It’s recommended to have a doctor conduct a face evaluation first before deciding, rather than setting the number of injections on your own.

Q: How long does it take to see results after getting the Phoenix Radio treatment?

A：For most people, the tightening effect starts to show gradually 1 to 3 months after treatment as Collagen begins to regenerate, though the actual time varies depending on individual skin conditions.

Q: Is Thermage FLX painful? Is there a recovery period needed?

A: You may experience a warm, swollen sensation during treatment. Clinics usually use anesthetic ointments or cooling systems to reduce discomfort. There’s generally no significant recovery period—most people can apply makeup and go out as usual the day after.

Q: What’s the difference between Thermage FLX and ultrasound (HIFU)?

A: Both are energy-based treatments, but they work through different mechanisms. Thermage FLX uses radio frequency (RF) energy that primarily targets the dermis layer to stimulate the production of new Collagen, while ultrasound delivers focused sound waves with deeper penetration, targeting the fascia layer. As for which one is better suited for you, it’s recommended that a doctor determine this based on the degree of sagging and your individual needs. Many people also opt to use both treatments together.

Q: What should I keep in mind before and after the treatment?

A: It’s recommended to avoid sunburn and keep your skin stable before the treatment. Afterward, focus on strengthening hydration and sun protection, and steer clear of high-temperature environments such as saunas and steam rooms for a while to give your skin enough time to recover.

Q: How long can the results generally last?

A: Results vary from person to person. For most people, the firming effect lasts around 1 year. The actual duration is influenced by factors such as age, lifestyle, and skincare habits. That’s why many choose to return for follow-up treatments every year or every 1 to 2 years to reinforce the results, rather than having just one treatment and calling it a day.

Q: What are the differences between Thermage FLX and other popular radiofrequency and ultrasound brands such as Ulthera, Oligio, and Volnewmer?

A: Different brands of RF radio wave or HIFU ultrasound technologies come with their own patented designs and parameter ranges, resulting in varying levels of effectiveness and suitability for different skin types. Rather than focusing solely on brand names, it’s recommended to consult a doctor who can explain the differences based on your specific skin condition, so you can decide which treatment is best for you.

Quick tip on common terms: RF (Radiofrequency, radio waves), HIFU (High Intensity Focused Ultrasound, focused ultrasound), Collagen (Collagen), and Downtime (recovery period) are all specialized terms you might encounter when consulting about treatment options. Understanding their meanings in advance will help you communicate more clearly with your doctor.
