What is Thermage FLX?
Thermage FLX is a monopolar radiofrequency treatment that tightens and smooths skin by heating the dermis and fibrous septae evenly over a wide area.
How Thermage FLX works
Radiofrequency energy heats collagen, causing immediate contraction and stimulating gradual remodeling. A cooling tip protects the surface while vibration improves comfort.
Who is Thermage FLX best for?
- crepey or loose skin
- fine texture and laxity across cheeks and neck
- eyelid hooding (with a dedicated eye tip)
- patients wanting skin quality rather than deep lift

Who should avoid or delay it?

Apgujeong insight
Many Apgujeong patients book Thermage and Ultherapy together as a 'layered lift': Ultherapy for depth, Thermage for surface tightness.
