What is Thermage FLX?
Thermage FLX is the current generation of Thermage, a device that has been used for skin tightening for many years. It uses monopolar radiofrequency (RF) — an energy that heats tissue as it passes through — delivered through a disposable tip that cools the surface while heating the deeper dermis.
That heat does two things. Immediately, existing collagen fibres contract, which is why some people feel a mild firmness right after treatment. Over the following months, the skin produces new collagen, which gives the more meaningful, gradual tightening.
Thermage FLX is often chosen for:
- Early laxity along the jawline and lower face
- Crepey skin on the cheeks and neck
- Hooded or crepey upper eyelids (Eye Thermage)
- People who want firmer skin without injections or downtime
It is not a substitute for a facelift, and it works best on mild to moderate laxity. For deeper structural lifting, the doctor may suggest Ultherapy alongside it.
Shot counts, areas and prices
Thermage is priced by the number of shots — the number of times the tip delivers energy. More shots allow more coverage or more passes on a problem area. The doctor recommends a count after examining your skin.
| Option | Typical coverage | Price |
|---|---|---|
| Thermage 300 shots | Full face, standard | β©1,200,000 |
| Thermage 600 shots | Full face with extra jawline passes | β©2,200,000 |
| Thermage 900 shots | Face plus neck | β©3,000,000 |
| Eye Thermage 225 shots | Upper and lower eyelids | β©1,000,000 |
| Eye Thermage 450 shots | Eyelids with extra passes | β©1,800,000 |
| Thermage 300 shots (first visit) | Full face, first-time patients | β©890,000 |
Thermage is often paired with a skin-quality treatment, such as Rejuran Healer, to address both firmness and texture. You can also read our general page on Thermage.

What Thermage FLX changes
Some firmness may be visible immediately, but the main tightening appears gradually over 2–3 months as new collagen forms. Results typically last about a year, after which many patients repeat. If you want a stronger lifting effect at deeper layers, compare it with Ultherapy.
How a Thermage FLX visit works
- Doctor consultation We assess laxity and skin thickness, mark the treatment grid, and agree a shot count.
- Numbing Numbing cream for 30–60 minutes. Eye Thermage uses protective eye shields.
- Treatment The cooled tip is moved across the grid; each shot feels like a brief hot pulse. 45–90 minutes.
- Aftercare Mild redness settles quickly; you can usually return to normal plans the same day.
Thermage is well suited to a short visit to Seoul because there is little visible downtime. Results continue to develop after you go home, so plan a follow-up photo comparison at around three months. Ask us about combining it with other tightening options.
Downtime, side effects and safety
Thermage FLX has a long safety record, but it is still a heat-based medical treatment:
- Common: redness, warmth and mild swelling for a few hours to a day; temporary tenderness.
- Less common: small raised bumps or grid marks that fade in days; temporary numbness.
- Rare: burns, blisters, changes in skin colour, or subtle loss of fat (contour change) when energy is too high — one reason settings are chosen by a doctor.
Not suitable or talk to us first if you
- Are pregnant or breastfeeding
- Have a pacemaker, defibrillator or other implanted electronic device
- Have metal implants in the treatment area
- Recently had fillers, threads or other energy treatments in the area
- Have active skin infection or a history of keloids
Afterwards, use gentle skincare and SPF, avoid saunas for a day or two, and stay hydrated.
Dr. Jimin Kang, Medical Director
Every thermage plan at Bailor starts with a face-to-face skin assessment by a doctor — not a sales counsellor. Dr. Kang's approach is "tailored, not templated": she chooses the product, dose and depth for your skin, and treats you herself or works alongside the other doctors on our in-house medical team.

Does Thermage FLX hurt?
Each shot feels like a brief hot pulse. Numbing cream and the device's cooling reduce discomfort, and energy can be adjusted during treatment.
How long does Thermage last?
Results typically last about a year, though this varies with age, skin and lifestyle.
Thermage or Ultherapy?
Thermage tightens skin evenly with RF; Ultherapy lifts deeper layers with ultrasound. The doctor will recommend one or both after examining you.
Is there downtime after Thermage?
Usually very little — mild redness for a few hours. Most people return to normal activities the same day.
