The Short Answer
What is Thermage FLX?
Thermage FLX is a non-surgical, non-invasive skin tightening treatment that uses monopolar radiofrequency (RF) energy. The RF heats the dermis and deeper tissue while the skin surface is cooled. This causes existing collagen to contract straight away and prompts the skin to build new collagen over the next few months.
It is designed for mild to moderate sagging, softening jawlines, crepey skin and fine lines. Thermage FLX is usually done in a single session, which makes it popular with visitors to Seoul. Most patients see some tightening soon after treatment, with the main improvement developing over 2–6 months.
