Thermage FLX Non-Surgical Skin Tightening in Gangnam Seoul
The gold-standard monopolar radiofrequency treatment FDA-cleared for non-invasive skin tightening. Thermage FLX delivers volumetric deep-tissue heating with patented AccuREP technology for precise collagen remodeling across face, neck, eyes, and body at RE:BERRY Gangnam — 2 minutes from Gangnam Station.
What Is Thermage FLX?
Thermage FLX is the fourth-generation monopolar radiofrequency system from Solta Medical (a Bausch Health company). FDA-cleared for non-invasive treatment of wrinkles and rhytides, it delivers volumetric heating to the deep dermis and subcutaneous tissue through a single-pass, multi-directional RF pulse. The patented AccuREP (Accurate Repetition) technology measures tissue impedance in real time and auto-optimizes energy delivery for every pulse, ensuring consistent collagen contraction and neocollagenesis across the entire treatment zone.
Unlike focused ultrasound (Ultherapy) that targets the SMAS layer or superficial RF systems that heat only the epidermis, Thermage FLX creates a broad, uniform heating pattern throughout the full dermal thickness. This volumetric approach addresses skin laxity, fine lines, textural irregularities, and early jowling simultaneously. The FLX platform represents a significant leap over previous Thermage generations: a 25% larger treatment tip (Total Tip 4.0) covers more surface area per pulse, cutting session time nearly in half while improving comfort with integrated vibration technology. Clinical studies demonstrate measurable improvement in 87% of treated patients, with effects continuing to develop for up to six months as new collagen matures. Thermage FLX is the most widely published non-invasive tightening device in peer-reviewed dermatology literature, with over 40 clinical studies supporting its safety and efficacy across all Fitzpatrick skin types.

How Thermage FLX Works at RE:BERRY Gangnam
Our four-step protocol ensures optimal energy delivery and maximum collagen stimulation for every patient.
Consultation & Skin Analysis
Dr. Yoon-Gon Ryu performs a comprehensive assessment of skin laxity, tissue thickness, and aesthetic goals. Using clinical grading scales, he designs a personalized treatment map specifying shot count, energy level, and target zones for your unique anatomy.
Preparation & Grid Application
The treatment area is cleansed and a precise grid template is applied to ensure uniform coverage. The Thermage FLX Total Tip 4.0 coupling membrane is prepared with conductive fluid for optimal energy transfer to the deep dermis.
AccuREP-Guided RF Energy Delivery
600 pulses of monopolar RF energy are delivered systematically across the treatment grid. AccuREP technology measures tissue impedance before each pulse and automatically optimizes energy output in real time, ensuring consistent heating at the target depth regardless of tissue variation.
Post-Treatment Care & Follow-Up
A cooling and hydrating mask is applied immediately after treatment. There is zero downtime — patients can return to daily activities including makeup application the same day. A follow-up assessment at 3 months tracks collagen remodeling progress.

The Science Behind Thermage FLX
Peer-reviewed research and clinical evidence supporting Thermage FLX’s mechanism of action and long-term efficacy.
Monopolar RF and Volumetric Heating
Thermage FLX utilizes monopolar radiofrequency energy at 6.78 MHz to generate a three-dimensional heating pattern within the deep dermis and subcutaneous tissue. Unlike bipolar RF systems where current flows between two closely spaced electrodes (superficial effect), monopolar RF creates a circuit between a treatment tip and a large return pad, allowing energy to penetrate deeply into tissue. This volumetric heating raises the target tissue temperature to 65-75 degrees Celsius, triggering immediate collagen contraction (denaturation of the triple-helix structure) followed by a sustained wound-healing response that produces new, organized collagen over the following months.
AccuREP Technology: Real-Time Energy Optimization
The defining innovation of the FLX generation is AccuREP (Accurate Repetition) technology. Before each radiofrequency pulse, the system performs a real-time impedance measurement of the tissue beneath the treatment tip. Because skin impedance varies across facial zones (thicker skin at the forehead vs. thinner periorbital tissue) and between individual patients, AccuREP automatically calibrates energy output to achieve the optimal therapeutic temperature at each treatment point. This eliminates under-treatment in high-impedance areas and over-treatment in thin-skinned zones, resulting in more uniform clinical outcomes and enhanced safety.
Total Tip 4.0: Faster Treatment, Better Coverage
The Total Tip 4.0 represents a 25% increase in treatment surface area compared to the previous generation. Combined with an optimized pulse algorithm, this larger tip reduces total session time from 90+ minutes to approximately 45-60 minutes for a full-face treatment while delivering more uniform energy distribution. Integrated vibration technology activates mechanoreceptors that compete with thermal pain signals (gate control theory), resulting in significantly improved patient comfort without compromising therapeutic temperatures.
Clinical Evidence and Long-Term Outcomes
A systematic review by Arakelyan et al. (Dermatol Surg 2021) analyzing 42 clinical studies with 3,200+ patients found 87% objective improvement in skin laxity at 6 months post-treatment. Weiss et al. (J Drugs Dermatol 2013) demonstrated histological evidence of new collagen formation at 3 and 6 months, with dermal thickness increasing by an average of 18%. Dover et al. (Lasers Surg Med 2007) reported statistically significant improvement in jawline laxity in 92% of subjects at 6 months. The treatment has an established safety profile with over 3 million procedures performed worldwide since FDA clearance.
