What is Thermage FLX?
Thermage FLX is a non-invasive radiofrequency (RF) skin-tightening treatment. It heats the deeper, collagen-rich layers of the skin so your body rebuilds collagen — making skin firmer and the jawline and face contour more defined, without surgery or downtime.
Unlike lasers, which work on the skin surface, Thermage FLX sends RF energy into the dermis and the layer beneath it. It is the latest generation of Thermage and one of the most requested lifting treatments in Seoul.
Thermage FLX is a one-session, no-downtime radiofrequency treatment that firms and lifts skin by rebuilding collagen.
