Thermage is a non-surgical skin-tightening treatment that uses monopolar radiofrequency (RF) to heat the deep layers of the skin. The current version, Thermage FLX, delivers controlled heat through a treatment tip while a vibrating comfort pulse and cooling protect the surface. The heat causes collagen fibers to contract right away, and over the following months the skin produces new collagen, so the face looks firmer and more lifted without cutting or injections.
Thermage is designed for mild to moderate skin laxity: softening jawline sagging, tightening cheeks, smoothing crepey texture, and refining the neck. It is a single-session treatment for most patients, which makes it convenient for international visitors, and it works on skin quality across a broad range of skin tones because RF is colour-blind, unlike some lasers that target pigment. It is not a substitute for a surgical facelift when there is significant excess skin.
At Reberry Clinic in Myeongdong, Seoul, Korea, Thermage is consultation-led. Dr. Seung Jae Baek, Medical Director, assesses your laxity, target zones, and skin quality, then builds a plan and explains it transparently in English. International patients are supported at our Myeongdong (Seoul) location, five minutes from Myeongdong Station, with multilingual help throughout consultation, treatment, and aftercare.
Thermage FLX uses monopolar radiofrequency, which passes a high-frequency electrical current through the skin. The skin’s natural resistance converts that current into heat, warming the deep dermis and fibrous septae to collagen-remodeling temperatures around 60 to 65 degrees Celsius while integrated cooling keeps the surface protected. Because the energy is monopolar, it heats a broad tissue volume rather than a single focused spot, which suits the goal of overall dermal tightening.
Two responses follow. First, the immediate heat causes existing collagen fibers to contract, giving an early tightening effect. Second, the controlled thermal injury signals the body to produce new collagen, a neocollagenesis process that builds gradually over 2 to 6 months. The FLX generation adds a larger tip, an AccuREP feature that calibrates energy to each area, and a vibrating comfort pulse that improves tolerability, so most patients complete treatment in a single session of a few hundred to several hundred pulses. This differs from micro-focused ultrasound devices such as Ultherapy Prime, which deposit energy at fixed focal depths in the SMAS; the clinic’s doctors weigh these mechanisms when matching the right tool to your face.

Dr. Baek grades facial and neck laxity and confirms your target zones in about 1 consultation before any treatment.
A treatment grid is applied and the tip selected, with settings calibrated so each of the several hundred pulses lands evenly.
The tip heats the deep dermis to around 60 to 65 degrees Celsius while cooling and a comfort pulse protect the skin surface.
Heated collagen fibers contract at once, so many patients notice subtle tightening within the first 2 to 4 weeks.
New collagen forms gradually, with firmness building over 2 to 6 months as neocollagenesis continues in the dermis.
A follow-up assesses results, and most patients repeat Thermage about once every 12 to 18 months to maintain firmness.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
At our Myeongdong (Seoul) location, Dr. Seung Jae Baek assesses laxity and target zones in English and confirms whether Thermage FLX fits your goals.
After prep and numbing, a Thermage session usually takes about 45 to 90 minutes depending on the area treated.
Thermage is typically a single session, with the several hundred RF pulses completed in one visit.
Some tightening appears within 2 to 4 weeks, and firmness continues to build over 2 to 6 months as collagen rebuilds.
Results often last around 12 to 18 months; sun protection and good skincare help, and many patients plan a maintenance session thereafter.
Thermage is a single-session, non-surgical treatment that uses monopolar radiofrequency to heat the deep dermis, contracting collagen immediately and building new collagen over months. This tightens facial and neck skin without surgery. Learn more on our Thermage FLX page at Reberry Clinic in Myeongdong, Seoul.
Thermage FLX is offered at our Myeongdong (Seoul) location, at 5, Myeongdong 10-gil, Jung-gu, about five minutes from Myeongdong Station. Dr. Seung Jae Baek, Medical Director, performs the assessment, and international patients receive English-language support throughout consultation, treatment, and aftercare planning.
Good candidates have mild to moderate facial or neck laxity, such as early jowls or crepey texture, and want a non-surgical option. Thermage tightens skin rather than removing it, so significant excess skin may need surgery. A consultation with the clinic’s doctors confirms whether Thermage fits your goals and skin.
Most patients tolerate Thermage well because a vibrating comfort pulse and cooling accompany each pulse, and numbing is used beforehand. You feel brief heat with each pulse, described as warm rather than painful for most people. Sensitivity varies, so tell Dr. Baek if any area feels too hot during treatment.
Downtime is minimal, with most patients returning to normal activities the same day. Mild redness or slight swelling can appear briefly and usually settles within hours to a day. Because it is non-surgical, it suits short trips. Compare with related lifting on our Ultherapy Prime page.
Some tightening appears within 2 to 4 weeks from immediate collagen contraction, while the fuller effect builds over 2 to 6 months as new collagen forms. This gradual timeline is normal for radiofrequency, so your skin keeps improving rather than peaking on treatment day.
Results commonly last around 12 to 18 months, though this varies with age, skin quality, and lifestyle. Because natural aging continues, Thermage is not a one-time fix; many patients schedule a maintenance session after a year or so to sustain firmer, smoother skin over time.
Thermage is usually a single session, unlike some ultrasound or booster protocols that need a course. One treatment delivers the pulses your plan requires, and results build over the following months. A maintenance session is typically considered after 12 to 18 months rather than in quick succession.
Thermage uses monopolar RF to heat a broad dermal volume, while devices like Sofwave and Ultherapy Prime use focused ultrasound at set depths. RF suits overall skin tightening; ultrasound suits deeper lifting. They are complementary, and your doctor recommends the best fit or a combination at consultation.
Yes, Thermage is often paired with ultrasound lifting, boosters, or fillers for a balanced result, sequenced so skin is not over-stressed. Combining with Ultherapy Prime can address both skin and deeper layers. Dr. Baek plans the order and timing at consultation based on your goals.
Thermage is generally considered safe when performed correctly, with cooling and calibrated energy protecting the skin surface. Temporary redness or swelling can occur, and rarely uneven results, which is why technique matters. A consultation screens for contraindications such as pregnancy or an implanted electronic device before treatment.
The most common effects are temporary redness, mild swelling, or brief tenderness that typically resolve within hours to a couple of days. Less commonly, small surface marks or uneven tightening can occur. Your doctor reviews these risks and aftercare with you so you know what to expect before proceeding.
Thermage cost depends on the tip type, area treated, and shot count, so pricing is confirmed at consultation rather than as a fixed figure. Because plans are individualised, Reberry Clinic explains cost transparently in English. See the broader approach on our Thermage FLX page first.
Yes, monopolar RF is largely colour-blind because it heats the dermis by resistance rather than targeting pigment, so Thermage is used across a broad range of skin tones. Settings are still tailored to your skin at consultation. This makes it a versatile option for many international patients seeking non-surgical tightening.
Aftercare is simple: apply daily sunscreen, keep skin moisturised, and avoid intense heat, saunas, and vigorous exercise for about 24 to 48 hours. A gentle skin care routine supports recovery. Dr. Baek gives tailored guidance so skin recovers comfortably while collagen rebuilds over the following months.
Two to three days is comfortable for a first Thermage visit, allowing a consultation, the single session, and a short review. Because downtime is minimal, many international patients combine it with sightseeing. Our English-speaking team at Myeongdong helps coordinate timing around your travel schedule.
Yes, flying within a day or so is generally fine because Thermage is non-invasive with little downtime. Cabin air is drying, so moisturise and protect treated skin from sun. If you notice unusual swelling, contact the clinic; our English follow-up means care continues after you travel home.
International patients can complete Thermage in a single Seoul visit and stay in touch through English remote check-ins afterward. Because results build over months, updates by message let Dr. Baek monitor progress and advise on maintenance timing. Your treatment notes are kept on file for continuity between trips.
