Radiofrequency surgery, also called RF or Radiosurgery, is the application of ultra-high frequency electrical current (radio waves) to the skin.
Radio waves are generated by a device called the Ellman Surgitron and applied to the skin using a specially-shaped electrode. The shape is selected depending on the procedure being performed.
Radio waves cause water molecules in cells to vibrate, which generates heat, and the water turns to steam. This causes cutting or coagulation (clotting) of the skin cells and blood vessels.
In the radiosurgery procedure, the mole or skin lesion is:
- Physically removed using a shaving motion, and/or
- Destroyed by heat (a process known as ablation).
