The fourth-generation evolution of Thermage FLX
Thermage FLX at Secret Clinic near Sinnonhyeon: monopolar RF, vibration and cooling, authentic tips, treatment process, precautions and consultation.

The fourth-generation evolution of Thermage FLX
Thermage FLX delivers monopolar radiofrequency energy to the dermis and subcutaneous tissue to support collagen contraction and remodeling. Energy and coverage require assessment of skin thickness, sensitivity and laxity direction.
Key features of Thermage FLX
- Non-incisional monopolar radiofrequency
- Possible initial feeling of tightness
- Larger 4.0 Total Tip
- Gradual change through collagen remodeling
- Tip selection for face and eye area
- A pathway designed around daily life
How Thermage FLX works
Radiofrequency energy reaches the dermis while cooling protects the surface. Collagen fibers may contract in response to heat, followed by remodeling during healing. Fine-line, texture and firmness changes are assessed gradually.
Vibration and cooling for comfort
Vibration and multi-stage cooling help protect the surface and manage discomfort during RF delivery. Sensation varies by area and individual sensitivity.
