How it works

How Thermage FLX works, in plain language

Thermage FLX uses radiofrequency (RF, a type of radio-wave energy) to warm the deeper layers of skin without a blade. Cooling protects the surface, and the warmth prompts your skin to make new collagen.
  1. 1

    Cooling and tuning start first

    A cooling system and automatic tuning begin as soon as treatment starts, so energy delivery is matched to your skin.

  2. 2

    Heat reaches deeper layers

    RF energy, delivered with gentle vibration, warms the dermis and the fat layer beneath it.

  3. 3

    Skin stays protected, then rebuilds

    Cooling continues through the final stage. New collagen builds over the following weeks.

How your skin responds

  1. Cooling and auto-tuning

    A cooling system and automatic tuning start as soon as treatment begins, calibrating energy delivery to your skin.

  2. Deep RF heating

    Monopolar radiofrequency energy, delivered with vibration, reaches deep into the dermis and the fat layer beneath it.

  3. Continuous cooling

    The cooling system runs throughout energy delivery to keep the skin surface protected.

  4. Protective finish

    Cooling continues through the final stage of treatment to protect the skin.
