Thermage FLX in Seoul

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

Thermage FLX in Seoul is a radiofrequency skin-tightening treatment offered at DERNA Clinic, located in Seocho-gu. Patients considering thermage flx seoul options often want to understand how the technology works, what results are realistic, and what a session actually involves before booking a consultation. This page outlines the treatment using only the information provided by the clinic, without exaggerated claims about outcomes.

What it is

Thermage FLX uses the Solta Thermage FLX device to deliver radiofrequency energy into the deeper layers of the skin. The goal is to stimulate the body's own collagen production, which may gradually improve skin firmness and reduce the appearance of fine lines. Unlike treatments that rely on injectables or fillers, Thermage works by heating tissue to encourage a natural remodeling response over time. At DERNA Clinic, the treatment is available in several formats, including 300, 600, and 900 shot protocols, along with a dedicated Eye Thermage option for the delicate skin around the eyes. The number of shots typically corresponds to the treatment area size and the degree of coverage a practitioner recommends during consultation.

Who it suits

Thermage FLX is generally considered by adults who notice early to moderate signs of skin laxity, such as softening jawline definition, mild sagging, or a loss of skin bounce. It is often chosen by people who prefer a non-surgical approach to addressing these concerns, or who want to complement other skincare routines with a collagen-stimulating procedure. Because results depend on each person's skin condition, age, and lifestyle factors, a consultation with one of the doctors at the clinic is the appropriate way to determine whether this treatment aligns with individual goals. Some patients pursue Thermage as a preventive measure before more visible aging changes appear, while others use it to address concerns that have already developed.

Who should avoid it

Not everyone is a suitable candidate for radiofrequency skin treatments. Individuals who are pregnant, have active skin infections or open wounds in the treatment area, or have certain implanted electronic devices such as pacemakers are typically advised against this procedure. People with active severe acne, certain autoimmune conditions affecting the skin, or a history of poor wound healing should discuss their situation carefully with a physician beforehand. Patients with unrealistic expectations about permanent or dramatic transformation should also reconsider, since Thermage produces gradual, variable improvement rather than a fixed guaranteed outcome. A thorough medical history review during consultation helps identify any contraindications specific to the patient.

How the session goes

A typical Thermage FLX session begins with a consultation where the treating doctor examines the skin and discusses the patient's concerns and expectations. The treatment area is cleaned, and a numbing cream or cooling protocol may be applied to improve comfort, since the device delivers heat during treatment. The practitioner then moves the Thermage tip across the skin in a grid pattern, delivering controlled radiofrequency pulses. Patients commonly describe a warming or tingling sensation with brief moments of heat during each pulse. The FLX platform includes a vibration feature designed to reduce discomfort compared with earlier Thermage generations. Session length varies depending on the number of shots selected and the size of the treatment area, so total time in the treatment room can differ from patient to patient.

Downtime and recovery

One of the appeals of Thermage FLX is that it generally does not require significant downtime. Most patients can resume normal daily activities immediately after the session. Some individuals notice mild redness or a warm sensation in the treated area for a few hours afterward, which usually subsides on its own. Because collagen remodeling is a gradual biological process, visible improvements in skin firmness typically develop over the following weeks to months rather than immediately after treatment. Results and timelines vary between individuals, and some patients may require a series of sessions or touch-ups to maintain their preferred appearance. Sun protection and gentle skincare are commonly recommended in the days following treatment to support skin recovery.

Pricing

The listed price for Thermage FLX at DERNA Clinic is 1,990,000 KRW. This figure should be treated as a reference point rather than a fixed quote, since VAT and the specifics of an individual consultation may affect the final cost. The exact protocol chosen, whether 300, 600, or 900 shots, or the addition of Eye Thermage, can also influence pricing. Patients are encouraged to confirm current pricing details and any applicable add-on costs directly with the clinic before scheduling a treatment.

Safety

Thermage FLX has been used in aesthetic clinics for skin tightening purposes, and at DERNA Clinic the treatment is administered by licensed medical doctors on staff. As with any energy-based skin procedure, there are potential risks, including temporary redness, swelling, or in rare cases blistering or changes in skin texture. A careful pre-treatment consultation helps the doctor assess suitability and reduce these risks. Patients should disclose their full medical history, including any skin conditions, prior cosmetic procedures, or implanted medical devices, so the treating doctor can make an informed recommendation. No treatment can be described as entirely free of risk, and individual responses to radiofrequency energy do vary.
