Thermage FLX in Gangnam, Seoul: Procedure, Results & Cost
Thermage FLX uses monopolar radiofrequency to tighten and firm the face, eyes, neck and body without needles or incisions.
Thermage FLX is the fourth-generation Thermage system, a monopolar radiofrequency (RF) device that heats deeper skin layers to remodel collagen. It suits mild to moderate laxity on the jawline, cheeks, eyelids, neck and some body areas. A full face takes about 45–60 minutes, redness usually fades within hours, and tightening develops over 2–6 months, typically lasting 12–18 months. Approximate Seoul pricing ranges from ₩900,000 (eyes) to ₩1,800,000–₩2,800,000 (full face).
What is Thermage FLX?
Thermage FLX is the 4th-generation Thermage system, with faster treatment times, more even energy delivery and improved comfort compared with earlier versions. It uses monopolar radiofrequency (RF) energy to heat the deeper layers of the skin (up to about 3 mm) while a cooling system protects the surface. The heat causes existing collagen to contract and stimulates new collagen production over the following months.
Thermage is FDA-cleared and commonly used for:
- Jawline definition
- Sagging cheeks and jowls
- Loose neck skin
- Crepey eyelids and fine lines around the eyes
- Mild laxity on the arms, abdomen or knees
Procedure at Nest Clinic Gangnam
- Consultation: the doctor assesses skin laxity and selects target areas and shot count.
- Comfort: numbing cream may be applied.
- Treatment: the handpiece delivers RF pulses with surface cooling. Patients describe a warm, deep heating sensation.
| Area | Approx. time |

Real result: Thermage FLX
Firmer contours develop gradually over 2–6 months after a single Thermage FLX session.
Recovery and aftercare
Mild redness usually fades within a few hours, and most people return to normal activities right away. Peeling and bruising are uncommon. Use sunscreen and keep the skin well hydrated. Rare side effects include temporary swelling, tenderness or small surface burns, which is why treatment should be done by trained medical staff with a genuine Thermage FLX device.
Results and who it suits
- Skin tightens gradually over 2–6 months after treatment.
- Usually one session; a touch-up after 12–18 months is typical.
- Best for mild to moderate laxity—not a replacement for surgery when there is significant excess skin.
- Often combined with HIFU such as Ultherapy for deeper lifting, or skin boosters for texture.
Results vary by age, skin thickness and lifestyle.
