Thermage FLX in Busan: Complete Guide for International Patients

October 25, 2026

Thermage FLX is one of the best-known skin-tightening treatments in Korea, and many visitors to Busan book it alongside a few days of sightseeing. Because it has no real downtime, it suits a short trip well. This guide explains how Thermage FLX works, who it is right for, what it costs in Seomyeon, and how to plan it around your flights.

Quick answer: Thermage FLX is a monopolar radiofrequency (RF) treatment that heats the deep dermis to tighten existing collagen and stimulate new collagen. It improves firmness, crepey texture and fine lines rather than giving a dramatic lift. A session takes about 30–60 minutes after around 30 minutes of numbing cream, and you can usually go straight back to your day. Results build over 2–6 months and typically last 6–12 months. In Seomyeon, Busan, packages start from KRW 1,890,000 before 10% VAT.

What is Thermage FLX?

Thermage FLX is the latest generation of the Thermage system made by Solta Medical in the USA. It uses monopolar RF energy, which passes through the skin and heats the deep dermis evenly across a wide area. While the tissue underneath warms, the treatment tip cools the skin surface and adds gentle vibration to make each pulse more comfortable.

The heat makes collagen fibres contract straight away, which is why some people feel slightly tighter on the day. More importantly, it starts a remodelling process: over the following months the skin produces new collagen, and the treated area becomes gradually firmer and smoother. Treatment is measured in shots (pulses), and common package sizes are 600 or 900 shots.

Thermage FLX vs older Thermage

Compared with earlier versions of the system, the FLX generation was designed to treat more evenly and efficiently, with a larger tip and software that adjusts energy delivery pulse by pulse. The underlying principle is the same: controlled RF heating of the dermis to tighten and remodel collagen. When you compare quotes, check that the device is genuine Thermage FLX and how many shots are included.

Who Thermage FLX suits

  • Thinning or crepey skin on the cheeks, jawline or neck.
  • People who want overall firmness and smoother texture rather than a strong lift.
  • Those who prefer one longer session a year to frequent clinic visits.
  • Eye area and neck concerns , since the device can be used on several areas with adjusted settings.
  • Travellers on a tight schedule who need a treatment with no downtime.

When something else may suit you better

  • Deeper sagging of the cheeks and jowls: focused ultrasound such as Ultherapy works at the deeper SMAS layer and is usually the first choice for lift.
  • Regular, lower-cost upkeep: other RF devices such as OligioX or Alltite are often chosen for monthly plans.
  • Fine lines and pores as the main concern: skin Botox or skin boosters may target these more directly.
  • Medical reasons: monopolar RF is generally avoided if you have a pacemaker or another implanted electronic device, metal implants in the treatment area, or are pregnant.

How much does Thermage FLX cost in Busan?

In Korea, Thermage FLX is usually sold as a package that includes a set number of shots plus a complementary skin treatment. Current packages at a clinic in Seomyeon include:

  • Thermage 600 shots + full-face skin Botox : from KRW 1,890,000
  • Thermage 900 shots + full-face skin Botox , which can be shared by two people: from KRW 2,590,000

Prices checked October 2026. They are in Korean won, exclude 10% VAT (added at payment) and are paid at the clinic on the day. Prices can change, so always confirm the current price for your visit date when you book.

Choosing 600 or 900 shots

600 shots generally covers the full face, while 900 shots allows more passes over looser areas or extra coverage such as under the chin. The doctor divides the shots between the cheeks, jawline, under the chin and forehead, and places more passes where the skin is loosest. The 900-shot skin Botox package can be split between two people travelling together, but each person needs their own consultation and the split depends on each face, so it may not be equal.

What happens on the day

  1. Message before you travel. Share the areas you want treated, a photo in daylight, your budget, and any implants or recent procedures.
  2. Consultation. The doctor assesses skin thickness, laxity and texture, and decides how many shots each zone needs.
  3. Numbing and marking. Numbing cream is applied for about 30 minutes, then a temporary grid is marked on the skin to guide even coverage.
  4. Treatment. The tip is applied pulse by pulse over about 30–60 minutes. Each pulse feels like a short burst of deep heat, eased by cooling and vibration. Energy is set to what you can tolerate, not simply the highest setting.
  5. Back to your day. The grid washes off and any flushing usually fades within hours.

Allow around two hours in total, including consultation and numbing. A morning or early-afternoon slot is easiest; the clinic opens Monday to Friday 10:00–20:00 and Saturday 10:00–16:00 KST, closed on Sundays, with lunch from 13:00 to 14:00.

Results: what to expect and when

  • Right after treatment: the skin may feel slightly tighter and look smoother.
  • Months 2–3: collagen remodelling makes the skin progressively firmer.
  • Around month 6: the result usually reaches its peak.
  • Months 6–12: the effect gradually fades with natural ageing; many people repeat treatment every 6–12 months.

Because the main change comes from slow collagen renewal, judging the result after a week is too early. Take a photo before treatment and compare at about three months in the same light. Age, skin thickness, sun exposure and smoking all affect how well and how long results hold, so daily sunscreen helps protect them.

Side effects, aftercare and safety

Thermage FLX is generally well tolerated when performed by a doctor. Common effects are redness, warmth or mild swelling that settles within hours to a day or two, and temporary tenderness. Rarely, burns, blisters, temporary surface irregularities or small areas of fat loss can occur, which is one reason careful energy settings matter more than maximum power.

Aftercare tips

  • On the day, avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise.
  • Use sunscreen carefully for 1–2 weeks.
  • Do not scratch or rub the treated area, and keep the skin well moisturised.
  • Makeup can usually be applied once redness has settled.

Who should wait or avoid it

Avoid Thermage FLX if you are pregnant, have a pacemaker or implanted electronic device, have metal implants in the area, have an active infection, open wound or cold sore there, or tend to form keloid scars. Tell the doctor about any recent fillers, threads or other procedures.

Planning Thermage FLX around a trip to Busan

With no real downtime, Thermage FLX fits even a weekend visit. You can go out for dinner or sightseeing the same evening, and flying is generally fine, even the next day. If you combine it with injectables such as skin Botox or Rejuran, or with a second device, mention your flight date at the consultation so the plan and timing suit your schedule.

The clinic is on the 8th floor of the Burger King building at 48 Seomyeon-ro, Busanjin-gu, about three minutes on foot from Seomyeon Station Exit 7. Seomyeon is where subway Lines 1 and 2 meet, so it is easy to reach from Haeundae, Busan Station or Gimhae Airport.

Thermage FLX vs other lifting options

  • Thermage FLX : monopolar RF heating the deep dermis. Best for: crepey skin, overall firmness, eye area.
  • Ultherapy : focused ultrasound to the SMAS, with imaging. Best for: sagging cheeks, jowls and brows.
  • OligioX : monopolar RF with cooling and vibration. Best for: regular firming sessions.
  • Shurink Universe : HIFU at set depths. Best for: jawline and affordable upkeep.

Thermage FLX and Ultherapy work at different depths, so they are often combined on the same day to treat skin quality and sagging together. The session is longer and you may feel more tender for a day or two, so plan a combination early in your trip.

Frequently asked questions

Does Thermage FLX hurt?

Numbing cream is applied first, and the tip cools and vibrates during each pulse. Most people feel short bursts of deep heat. Tell the doctor if a pulse feels too hot, as the level can be adjusted.

Most people have a single session and repeat it every 6–12 months to maintain the effect. Some add lower-cost RF or skin treatments in between.

Do international patients pay the same price?

Listed prices are in KRW, exclude 10% VAT and are paid at the clinic on the day. If you pay by card, your bank converts the amount at its own exchange rate. Confirm the price for your visit date when you book.

Ultherapy is one of the most requested non-surgical lifting treatments in Korea, and Busan has become a popular place to have it done, especially for visitors who want to combine a treatment with a city break by the sea. This guide explains how Ultherapy works, who it suits, what it costs in Busan, and what recovery really looks like, so you can decide whether it fits your goals and your travel plans. Quick answer: Ultherapy uses focused ultrasound, guided by real-time imaging, to heat the deep supporting layer of the face (the SMAS) and trigger new collagen. A session takes about 30–60 minutes after numbing cream, there is usually no downtime, the lift builds over 2–6 months, and results typically last 6–12 months. In Busan, packages generally start from around KRW 790,000 before 10% VAT. What is Ultherapy? Ultherapy (often called Ulthera) is a micro-focused ultrasound device made by Merz Aesthetics. Like other HIFU treatments, it delivers concentrated ultrasound energy beneath the skin. What sets it apart is its built-in imaging: the practitioner can see the layers of the skin on screen and place each line of energy at the intended depth, including the SMAS, the same layer that is tightened in a surgical facelift. Each line creates tiny heated points that contract the tissue and start the body's collagen renewal process. Rather than an instant change, the skin firms and lifts gradually over the following months. Benefits of Ultherapy Reaches the deep support layer. Energy can be delivered down to the SMAS, which is why Ultherapy is used for sagging rather than surface texture alone. Imaging-guided precision. Seeing the tissue before each line helps place energy where it is needed and away from bone. No incisions and no downtime. Most people return to their day straight away. Natural, gradual change. The lift develops as collagen rebuilds, so results look like your own face, only firmer. One session a year for many people. A single treatment is usually enough for a visible change, repeated every 6–12 months. Who is a good candidate? Ultherapy tends to suit people in their 30s to 60s whose cheeks, jowls or brows have started to drop, or who have a softer jawline and some looseness under the chin. It is less helpful when the main concern is crepey texture rather than sagging (radiofrequency treatments such as Thermage FLX often suit that better), or when the face is very thin and hollow, in which case restoring volume may matter more than tightening. How much does Ultherapy cost in Busan? Ultherapy is priced by the number of lines (shots). Around 300 lines is typical for targeted areas such as the jawline and lower cheeks, while around 600 lines allows fuller coverage of the face and under the chin. In Busan, Ultherapy is often sold as a package combined with a skin booster or skin Botox. Ultherapy 300 lines + full-face skin Botox : from KRW 790,000 Ultherapy 600 lines + full-face skin Botox : from KRW 1,690,000 Prices checked October 2026. Korean clinic prices for cosmetic treatments are quoted in won and exclude 10% VAT, which is added at payment. Prices can change, so always confirm the current price when you book. When comparing quotes, check the number of lines included, whether the device is genuine Ultherapy or Ultherapy PRIME rather than a different HIFU machine, what is bundled in the package, and whether VAT is included in the figure you were given. What happens during a session Consultation. The doctor assesses sagging, fat and skin thickness, then plans the areas, depths and number of lines. Numbing. Numbing cream is applied for about 30 minutes, then the skin is cleansed and a gel is applied for the imaging probe. Treatment. The transducer shows the skin layers on screen and delivers focused ultrasound over about 30–60 minutes. Areas close to bone, such as the jawline, can feel prickly or warm. Straight back to your day. Mild redness is common and usually fades within hours. Results: what to expect and when Right after treatment: some people notice slight tightening; mild redness is normal. Months 2–3: lifting and firmness become visible as collagen renews. Months 3–6: results usually reach their peak. Months 6–12: the effect gradually fades with natural ageing; a repeat session maintains it. Results and timing vary from person to person. Even, well-planned coverage matters more for a natural result than simply using the maximum number of lines. Recovery, side effects and aftercare Ultherapy has very little downtime. The most common effects are redness or mild swelling that settles within hours to a few days, and tenderness or a bruised feeling along the jaw that can last a few days. Rarely, people experience temporary numbness, small bruises, welts or nerve irritation. Aftercare tips On the day of treatment, avoid saunas and jjimjilbang, hot baths, alcohol and strenuous exercise. Use sunscreen carefully for 1–2 weeks and avoid rubbing or scratching the treated area. Keep the skin well moisturised; makeup can usually be applied once the skin has calmed. Who should wait or avoid it Ultherapy is not recommended during pregnancy, over an active skin infection, open wound or severe acne in the area, or near metal implants or a pacemaker. Tell your doctor about any recent fillers, threads or other procedures in the area. Planning Ultherapy around a trip to Busan Because there is no real downtime, Ultherapy fits easily into a short stay. You can usually go sightseeing the same afternoon, and flying is generally fine, although jaw tenderness can feel more noticeable when chewing on the plane. Booking the treatment early in your trip gives you a few days to settle before you fly home. Share your flight date at the consultation so the plan fits your schedule. Ultherapy vs other lifting options Ultherapy : Focused ultrasound with real-time imaging. Best for: sagging cheeks, jowls and brows. Ultherapy PRIME : Newer Ultherapy platform with upgraded imaging. Best for: the same goals on the latest hardware. Thermage FLX : Monopolar radiofrequency heating the deep dermis. Best for: crepey skin and overall firmness. Shurink Universe : HIFU at set depths, without imaging. Best for: jawline and budget-friendly maintenance. In short, choose Ultherapy for an imaging-guided lift of deeper sagging, Thermage FLX when skin texture is the bigger concern, and Shurink Universe for more frequent, lower-cost upkeep between sessions. Frequently asked questions Does Ultherapy hurt? Most people describe it as warm, prickly pulses, strongest over bony areas. Numbing cream is applied beforehand to keep it comfortable. How many sessions will I need? One session is usually enough for a visible change. Many people repeat it every 6–12 months to maintain the result. Is 300 or 600 lines right for me? 300 lines generally focuses on priority areas such as the jawline and lower cheeks, while 600 lines covers the full face and under the chin more thoroughly. The right number depends on your degree of sagging and the areas you want treated. Thinking about Ultherapy in Busan?
