Radio waves are a band of wavelengths that can be used for skin surgery and mole removal by shaving. They are high frequency wavelengths that generate minimal heat. The wavelength that is optimal for skin surgery is a frequency of 4.0 megahertz (MHz), which is similar to the frequency of marine band radios. This wavelength when channeled through an electrode tip, can cut the skin as well as simultaneously coagulate blood to produce a bloodless incision. Also, as it has minimal heat generated, surrounding tissues are unaffected.
