Incheon AirportHow much is Thermage FLX in Gangnam, and what does it do?
₩1,990,000 ($1,421 USD) buys Thermage FLX 600 shots at RE:BERRY in Gangnam, Seoul — an FDA-cleared monopolar radiofrequency treatment that heats the dermis in bulk to trigger collagen remodeling and skin tightening in a single session with no downtime, performed by a licensed physician at a price published before you book.
Effects & Progress
Effects & Progress
Monopolar radiofrequency warms a broad, deep volume of the dermis in a single session, so tightening develops evenly across the treated area rather than at isolated points.
Mild warmth or light pinkness may appear in the treated zones and usually settles within hours. Makeup and daily life — including travel — are fine the same day.
Early firmness from collagen contraction settles in. The skin often feels denser and smoother to the touch before the visible tightening reaches its peak.
The main tightening phase — new collagen builds through the warmed dermal layer, and the cheeks, jawline, and eye area look progressively firmer. Response speed varies by individual.
Maintenance period. Results from a single session generally last one to two years; RE:BERRY will guide the repeat interval that suits your skin.

- Single-session tightening with no downtime: one 600-shot Thermage FLX treatment heats the dermis in bulk at a 3mm working depth, and you return to normal life — including flights — the same day
- Published price you can verify before booking: Thermage FLX 600 shots is ₩1,990,000 ($1,421 USD) at RE:BERRY Gangnam, VAT included, and the bill matches that figure with no add-on charges
- AccuREP pulse-by-pulse calibration: the FLX platform measures skin impedance and re-tunes the energy before each of the 600 shots, so delivery adapts to every zone rather than running one fixed setting
- Eye-area capability: Thermage carries FDA clearance for treating the delicate eyelid region with a dedicated 0.25cm² eye tip — a 450-shot Eye Thermage FLX session addresses hooding and crepey lids without needles or surgery
- Same physician from consultation through all 600 shots to your review — your Thermage FLX case in Gangnam is never passed to another practitioner mid-course
- Genuine, MFDS-registered device and sealed single-use tips verified in front of you, with your skin condition documented under standardized clinic lighting before and after
| Timeline | What to Expect |
|---|---|
| Session complete in 45-90 minutes; mild warmth and pinkness fade within hours — makeup, flying, and dinner reservations are all fine the same day | |
| Early firmness from immediate collagen contraction settles in; the skin often feels denser to the touch before the visible change peaks | |
| New collagen builds along the treated cheeks, jawline, and eye area as the heated dermal volume remodels | |
| The fullest tightening is visible between months 2 and 6; a single Thermage FLX session typically holds 12-24 months |
Thermage FLX vs Ultherapy Prime vs Onda — Choosing a Tightening Path in Gangnam
| Criteria | Thermage FLX (RE:BERRY Gangnam) | Ultherapy Prime (HIFU) | Onda Lifting (Microwave) |
|---|---|---|---|
| Energy type | Monopolar radiofrequency (RF) | HIFU / MMFU focused ultrasound | Microwave (Coolwaves) 2.45GHz |
| How it heats | Broad dermal volume heating at a 3mm working depth | Discrete focal points at 1.5 / 3.0 / 4.5mm reaching the SMAS | Uniform heating from dermis into subcutaneous fat, 3mm + 7mm handpieces |
| Suited for | Overall skin looseness, texture, and eye-area laxity | Sagging, jowls, jawline definition | Laxity with soft-tissue fullness, face and body |
| Eye-area use | FDA-cleared eyelid treatment with 0.25cm² eye tip | Not used on the eyelids | Not an eyelid treatment |
| Sessions needed | Single session | Single session | Often planned as a short series |
| Session time | 45-90 minutes for 600 shots | 30-60 minutes | 30 minutes |
| Downtime | None — same-day makeup and flights | 24-72 hours mild redness | Immediate return to daily life |
| Peak result | 2-6 months, holds 12-24 months | Week 12, holds 12-18 months | Builds across the treatment series |
| Published price | ₩1,990,000 ($1,421 USD) / 600 shots | Published on its treatment page | Consultation required |
Why This Matters
These three devices are not interchangeable: Thermage FLX is monopolar RF that heats a broad dermal volume for tightening, Ultherapy Prime is focused ultrasound that lifts at the SMAS, and Onda uses microwave energy that reaches into subcutaneous tissue. Many RE:BERRY Gangnam patients stage RF tightening with a HIFU lift because the two act on different layers.
Seoul pricing is a large part of why Thermage FLX in Gangnam draws medical travelers. RE:BERRY publishes 600 shots at ₩1,990,000 ($1,421 USD) VAT included, while the same FLX session with a genuine 600-shot tip commonly runs 50-70% higher in the US and materially higher in Japan and Australia — an advantage Seoul retains into 2026 on the published rate alone.
In 2025, 87.2% of the international patients who came to Korea were treated in Seoul (MOHW) — a crowded field where the real difference lies in who actually holds the handpiece. At RE:BERRY the physician who maps your laxity plans the pass pattern, delivers all 600 shots, and reads your review, with no handoff between stages.

The Evidence Behind Thermage FLX Monopolar RF Tightening
Thermage FLX is a fourth-generation monopolar radiofrequency (RF) device: a 6.78 MHz current passes through the skin between the treatment tip and a return pad, and tissue resistance converts that current into heat throughout a broad dermal volume at a 3mm working depth. Histological and ultrastructural analysis of skin treated with this monopolar RF platform documented immediate partial denaturation of collagen fibrils followed by increased collagen expression during repair — the two-phase mechanism behind both the early firmness and the tightening that builds over 2-6 months.
Zelickson BD, Kist D, Bernstein E, et al. Histological and ultrastructural evaluation of the effects of a radiofrequency-based nonablative dermal remodeling device: a pilot study. Arch Dermatol. 2004;140(2):204-209. doi:10.1001/archderm.140.2.204
Clinical outcome data track that mechanism at scale. A multicenter periorbital study of 86 subjects recorded objective brow elevation of at least 0.5mm in the majority of patients at 6 months after a single monopolar RF session, supporting the eye-area indication Thermage now carries. A separate physician survey covering 5,700 monopolar RF facial treatments found that the multiple-pass, moderate-energy protocol — the approach RE:BERRY uses across all 600 shots — produced visible tightening in 87% of cases immediately and in 92% at 6 months, alongside markedly better patient comfort than the original single-pass, high-energy technique.

Evidence in Asian skin matters for a Seoul clinic: a Japanese series applying non-ablative monopolar RF tightening reported measurable laxity improvement sustained through 6-month follow-up with no scarring or pigmentary change — relevant because RF energy is chromophore-independent and does not target melanin. A 66-patient lower-face study of the multiple-pass, low-fluence algorithm likewise confirmed progressive contour improvement through 6 months. This is why the physician at RE:BERRY Gangnam screens laxity type first: broad dermal looseness responds to the 600-shot Thermage FLX protocol, while deep fold-dominant sagging is redirected to a different energy class.

Questions International Guests Ask About Thermage FLX in Gangnam
How much does Thermage FLX cost in Gangnam, Seoul in 2026?
₩1,990,000 ($1,421 USD) covers Thermage FLX 600 shots for the full face at RE:BERRY Gangnam — the regular rate, VAT included, published before you book with no add-ons. Eye Thermage FLX 450 shots is ₩2,500,000 ($1,786 USD). The home page price section lists the full tightening line-up.
How does Thermage pricing in Korea compare with the US and Japan?
Seoul runs 50-70% below typical US pricing for a genuine 600-shot Thermage FLX session, and below Japan as well.
| Market | How it compares |
|---|---|
| Korea (RE:BERRY Gangnam) | ₩1,990,000 ($1,421 USD), published, VAT included |
| USA | Commonly 50-70% higher than Seoul |
| Japan | Typically 30-50% higher than Seoul |
| UK / Australia | Materially higher than Seoul |
How many Thermage shots do I need — is 600 enough for the full face?
600 shots is the standard full-face Thermage FLX protocol at RE:BERRY Gangnam, delivered with the 4.0cm² Total Tip across cheeks, jawline, and under-chin in one session. The eye area uses a separate 450-shot protocol with the 0.25cm² eye tip. The physician confirms your shot plan after mapping your laxity at consultation.
What is Thermage FLX, and how does monopolar RF tightening work?
Thermage FLX is an FDA-cleared, fourth-generation monopolar radiofrequency device: a 6.78 MHz current heats a broad volume of dermis at a 3mm working depth, contracting existing collagen and triggering months of new collagen production. It is not ultrasound, laser, or microwave — RF heats by tissue resistance, which is why one session at RE:BERRY Gangnam tightens without any wound.
Thermage FLX vs Ultherapy Prime — which should I choose in Gangnam?
Choose by mechanism: Thermage FLX is monopolar RF that tightens broad skin looseness, while Ultherapy Prime is focused ultrasound that lifts sagging at the SMAS.
| Feature | Thermage FLX | Ultherapy Prime |
|---|---|---|
| Energy | Monopolar RF | HIFU ultrasound |
| Suited for | Surface looseness, eye area | Sagging, jowls |
| Downtime | None | 24-72 hours redness |
How is Thermage FLX different from Onda lifting?
The energy class differs: Thermage FLX uses monopolar radiofrequency for bulk dermal heating at 3mm, while Onda uses 2.45GHz microwave energy that reaches from dermis into subcutaneous fat with 3mm and 7mm handpieces.
| Feature | Thermage FLX | Onda |
|---|---|---|
| Energy | Monopolar RF | Microwave (Coolwaves) |
| Sessions | Single | Often a series |
| Eye area | FDA-cleared eye tip | Not an eyelid treatment |
Does Thermage FLX hurt, and what does the comfort protocol include?
Each of the 600 pulses brings a brief wave of deep warmth rated manageable by most guests: the FLX handpiece pairs vibration with integrated surface cooling, and AccuREP re-tunes the energy before every shot so no zone is overdriven. At RE:BERRY Gangnam the physician also adjusts intensity to your feedback throughout the 45-90 minute session.
Is there any downtime after Thermage FLX — can I fly home the same day?
No downtime — mild warmth and pinkness fade within hours after Thermage FLX, and there is no wound, so makeup, flights, and sightseeing are all fine the same day. That makes the 600-shot session at RE:BERRY Gangnam one of the easiest treatments to fit into a short Seoul itinerary, even a 2-day stopover.
When will I see Thermage FLX results, and how long do they last?
Results build in two phases: an early firmness from immediate collagen contraction within the first weeks, then the main tightening between months 2 and 6 as new collagen forms in the heated dermal volume. A single 600-shot Thermage FLX session typically holds 12-24 months before a maintenance session at RE:BERRY Gangnam is considered.
Am I a good candidate for Thermage FLX, or should I consider a different treatment?
Good candidates have mild-to-moderate skin looseness — softening jawline, crepey cheeks, or lax eyelids — and want one session with zero downtime. Thermage FLX is not scheduled for guests with a pacemaker or other implanted electronic device, or during pregnancy. Deep structural sagging responds better to SMAS-level lifting, which the physician at RE:BERRY Gangnam screens for first.
What aftercare does Thermage FLX need once I return home?
Aftercare is light: for 7 days avoid saunas, very hot showers, and intense heat exposure, keep the skin moisturized, and use daily sun protection while collagen remodels over the following 2-6 months. RE:BERRY Gangnam includes 90 days of WhatsApp follow-up in English, reviewing your progress photos as the tightening from your session develops.

Where exactly is the clinic, and how do I get there from Gangnam Station?

Being steps from the station means your Thermage FLX appointment slots cleanly between Gangnam sightseeing, dining, and shopping.

Science Thermage FLX monopolar RF tightening — peer-reviewed references
Monopolar radiofrequency tightening rests on two decades of peer-reviewed evidence, beginning with histological proof of its mechanism: Zelickson (2004) documented immediate partial collagen fibril denaturation and subsequent new collagen expression in treated skin. Clinical outcomes followed at every scale — a multicenter periorbital trial of 86 subjects measured objective brow elevation at 6 months (Fitzpatrick 2003), a 14-physician survey spanning 5,700 facial treatments reported visible tightening in 92% of cases at 6 months under the multiple-pass, moderate-energy protocol (Dover 2007), and a dedicated 66-patient lower-face study confirmed the same algorithm's progressive contour gains (Bogle 2007). Evidence in Asian skin (Kushikata 2005) showed sustained laxity improvement with no pigmentary change, reflecting that RF heating is chromophore-independent. Follow-up of 290 patients across nonablative RF treatments recorded only transient, self-resolving reactions (de Felipe 2007).
