Thermage FLX in Korea: Complete Guide to Prices, Effects & Best Clinics 2025
Looking for a non-surgical way to tighten sagging skin and boost collagen? Thermage FLX—known as 써마지 (sseomaji) in Korean—is one of the most sought-after skin tightening treatments in Korea. This FDA-approved radiofrequency treatment has helped millions achieve firmer, more youthful-looking skin without going under the knife.
What is Thermage FLX?
Thermage is a brand-name device that uses radiofrequency (RF) energy to heat the deeper layers of skin, stimulating collagen production and tissue remodeling. The latest generation, Thermage FLX (4th generation), offers improved comfort, faster treatment times, and enhanced results compared to previous versions.
How It Works:
- RF energy penetrates from the epidermis to the SMAS layer (muscle fascia)
- Heat causes immediate collagen contraction (instant tightening)
- Triggers new collagen production over 3-6 months
- Results in gradual lifting and firming effect
Thermage FLX vs. Ulthera: What's the Difference?
These two treatments are often compared. Here's how they differ:
| Feature | Thermage FLX | Ulthera |
|---|---|---|
| Technology | Radiofrequency | Ultrasound (HIFU) |
| Depth | Epidermis to SMAS | Focused on SMAS |
| Best For | Overall tightening, texture | Lifting, defining contours |
| Pain Level | Moderate | Higher |
| Price (Full Face) | $400-600 | $400-800 |
| Sessions Needed | 1-2/year | 1/year |
Many Korean dermatologists recommend combining both treatments for optimal results—Thermage for surface tightening and Ulthera for deep lifting.
