Medically reviewed by Kim Yunseok, CEO / Representative Director · Last updated July 2026

Thermage FLX Seoul treatments are available at DERNA Clinic, located at B2F, 17 Seocho-daero 77-gil, Seocho-gu, Seoul. This page explains what the treatment involves, who tends to benefit, and what to expect before booking a consultation. If you are researching Thermage FLX Seoul options while planning a visit, the details below should help you understand the basics before speaking with a doctor in person.

What it is

Thermage FLX is a radiofrequency skin-tightening treatment that uses the Solta Thermage FLX device. The device delivers controlled radiofrequency energy into the deeper layers of the skin, which is intended to stimulate the body's own collagen production over time. Unlike surgical facelifts, it does not involve incisions. Sessions are offered in different intensity levels, commonly described as 300, 600, and 900 shot options, along with an Eye Thermage option designed for the thinner skin around the eye area. The specific shot count and settings used depend on the treatment area and the doctor's assessment during consultation.

Results are generally described as gradual improvements in skin elasticity and a softening of fine lines, rather than an immediate dramatic change. Because collagen remodeling is a biological process, visible improvement typically develops over the weeks following treatment rather than appearing instantly.

Who it suits

Thermage FLX is often considered by patients who notice early signs of skin laxity, mild sagging, or fine lines but who are not seeking or ready for surgical intervention. It may also be used as a maintenance treatment by patients who have had previous facial procedures and want to support skin firmness. Because individual skin condition, age, and lifestyle factors vary widely, the degree of improvement differs from person to person, and no specific outcome can be promised in advance.

Patients considering Thermage FLX Seoul treatment are encouraged to discuss their skin concerns, medical history, and expectations directly with a doctor at the clinic before scheduling a session.

Who should avoid it

Radiofrequency treatments are not suitable for everyone. Patients who are pregnant, have active skin infections or open wounds in the treatment area, have certain implanted electronic devices such as pacemakers, or have specific skin conditions may need to avoid or delay treatment. Patients with a history of keloid scarring or those currently using certain medications should disclose this during consultation. A doctor at the clinic will review medical history before confirming whether the treatment is appropriate for a given patient. This page does not replace a personal medical evaluation.

How the session goes

A typical visit begins with a consultation and skin assessment, during which the treating doctor determines the recommended shot count and treatment area. The skin is cleansed and a numbing cream or cooling method may be applied to improve comfort, since radiofrequency energy can produce a warming or tingling sensation. The device tip is then moved across the treatment area in a grid-like pattern, delivering pulses of energy at set intervals. Many patients describe the sensation as heat with brief moments of more noticeable warmth, and comfort levels can vary depending on the treatment area and individual pain tolerance. Depending on the shot count selected, a session can take anywhere from under an hour to a longer appointment for higher shot counts or combined areas such as the eyes and face.

Downtime and recovery

One appeal of Thermage FLX is the limited downtime compared with surgical procedures. Most patients can return to normal daily activities shortly after the session. Some mild redness, warmth, or slight swelling in the treated area is common immediately afterward and typically settles within a short period, though this can vary between individuals. Sun protection and gentle skincare are generally advised in the days following treatment. Since collagen remodeling is a gradual process, visible changes in skin firmness usually continue to develop over subsequent weeks, and results are not identical for every patient.

Pricing

This price reflects the treatment as listed by the clinic. VAT and consultation fees may apply separately and can vary depending on the shot count selected, additional areas treated, or whether Eye Thermage is combined with a facial session. Patients should confirm final pricing with the clinic directly before booking, as costs may be adjusted based on individual treatment plans.

Safety

Thermage FLX has been used in aesthetic clinics for skin tightening purposes, and radiofrequency-based treatments are generally considered to carry a different risk profile than surgical procedures, though they are not without risk. Possible side effects can include temporary redness, swelling, or, in rare cases, more noticeable skin reactions. As with any energy-based device, outcomes and tolerability vary between patients, and results cannot be guaranteed. Patients are encouraged to share full medical history, including prior cosmetic procedures and any skin conditions, with the treating doctor so that settings can be adjusted appropriately. DERNA Clinic's medical team includes doctors with varied backgrounds in aesthetic and surgical practice; treatment plans are determined individually rather than following a fixed protocol for every patient.

Frequently asked questions

How many sessions of Thermage FLX are usually needed?

Many patients undergo a single session and monitor results over the following weeks, though some may consider a follow-up session depending on their skin condition and the doctor's recommendation during consultation.

Is Thermage FLX painful?

Most patients describe a warming or tingling sensation during treatment rather than significant pain, and numbing measures are typically used to improve comfort, though tolerance varies by individual.

How soon will I see results after Thermage FLX in Seoul?

Because the treatment works by stimulating collagen over time, visible improvements in skin firmness generally develop gradually over the weeks following the session rather than appearing immediately.

Can Thermage FLX be combined with other treatments?

Combination treatment plans are sometimes discussed during consultation, but any combination depends on individual skin assessment and should be confirmed directly with the treating doctor at DERNA Clinic.

What should I do before booking a Thermage FLX consultation at DERNA Clinic?

It is helpful to prepare a summary of your skin concerns, relevant medical history, and any previous cosmetic procedures, and to contact the clinic by phone or email to arrange a consultation appointment.
