The short answer. Thermage FLX is a monopolar radiofrequency treatment from Solta Medical in the United States, used to firm skin that has lost elasticity. At Beauty Z Clinic Myeongdong in Seoul, 300 face shots cost ₩990,000 and 600 face shots cost ₩1,850,000, while the eye plans come in 225 shots for ₩990,000 or 450 shots for ₩1,790,000. It takes a single visit, makeup can go on as you leave, and the clinic sits right by Exit 6 of Euljiro 1(il)-ga Station.
Thermage FLX Prices at Our Myeongdong Clinic

Payment is made in won, and the full price list adds an approximate US dollar figure beside each option, so you can compare costs before you fly. The doctor settles the shot count at consultation, once it is clear how much laxity there is and where it sits.
Face Plans and Eye Plans
The 300 and 600 shot options are for the face. The doctor looks at how far elasticity has dropped and which areas need the most attention, then suggests one count or the other.
Eye Thermage FLX is booked as its own plan of 225 or 450 shots. Among the uses the U.S. FDA has cleared for this system, Solta Medical names wrinkles around the eyes, with the eyelids included, treated without surgery. If fine lines or loose skin around the eyes are your main concern, the doctor will talk you through the eye plan at consultation.
How Thermage FLX Works
Thermage FLX passes monopolar radiofrequency energy through the surface of the skin and turns it into heat in the dermis. That heat makes existing collagen contract and sets off the production of new collagen, so elasticity keeps improving for months after the visit.
The system is made by Solta Medical in the United States and holds U.S. FDA 510(k) clearance K170758. Every pulse delivers a short burst of heat that the handpiece follows with cooling, and the energy level is set to match your skin.
Thermage FLX Compared with Ultherapy Prime and Volnewmer
Thermage FLX is often weighed against Ultherapy Prime, and the two reach different layers. Radiofrequency heats the dermis, while the focused ultrasound of Ultherapy Prime travels further down to the SMAS.
| Device | Works on | Often chosen for | From |
|---|---|---|---|
| Thermage FLX, Solta Medical | Dermis, monopolar RF | Lost elasticity, fine lines, the eye area | ₩990,000, 300 shots |
| Ultherapy Prime, Merz Aesthetics | SMAS, focused ultrasound | A softened jawline, double chin, sagging cheeks | ₩890,000, 300 shots |
| Volnewmer, Classys | Dermis, 6.78 MHz monopolar RF | Thin, delicate skin, planned as a course | ₩350,000, 300 shots |
When sagging and lost elasticity appear together, the package of 600 Ultherapy Prime shots with 600 Thermage FLX shots treats both layers in one plan. The Ultherapy and Thermage comparison goes through each concern in turn, and our articles on Ultherapy Prime shot counts, ONDA Coolwaves and Volnewmer prices cover the other devices. The lifting guide lists every device we offer with its starting price.
Pain and Comfort During Treatment
Solta Medical notes that mild to moderate pain where the tip works is the effect most often reported during a session. Each pulse feels like a short spell of heat, and cooling follows straight after.
Tell the doctor during the session if a spot feels too strong, since the energy is adjusted for you. People with a cardiac pacemaker cannot have Thermage FLX, so mention any implanted device at consultation.
How Long Thermage FLX Lasts
Some people notice firmer skin as soon as the session ends. The larger change comes as collagen rebuilds, with elasticity improving gradually over roughly 2 to 6 months, and the clinic suggests a maintenance session every 6 to 12 months. How long the result holds depends on your skin and the degree of aging, so the doctor plans the next visit around what they see.
Who Thermage FLX Suits
Thermage FLX is a good match for these four concerns.
- Skin that has lost elasticity
- Facial contours that have begun to sag
- Fine lines and early signs of skin aging
- Wrinkles around the eyes, eyelids included, with the eye plan
For thin, delicate skin the doctor may point you toward Volnewmer instead, and for a jawline that has lost its definition, toward Ultherapy Prime.
Your Thermage FLX Visit, Step by Step
A visit runs in four steps, and the treatment itself takes about 30 to 60 minutes for most people, according to the manufacturer.
Planning Thermage FLX Around a Short Stay in Seoul
Thermage FLX needs only one appointment and makeup can go back on before you leave, which makes it easy to fit into a short trip. Saunas and jjimjilbang should wait about a week afterward, so book the bathhouse for the days before treatment. Most of the collagen change develops after you are home.
Aftercare for the First Week
- Redness, swelling, heat, tingling, dryness, itching or a burning feeling may appear briefly. Contact the clinic if any of it lasts.
- Vitamin C or another antioxidant is recommended for the days that follow.
