What is radiofrequency?

Radiofrequency is the term given to any alternating electrical current that, if applied to an antenna, creates an electromagnetic field that propagates through space in the surrounding area. The frequencies of radio waves in this group can be anything from 3 kilohertz (kHz) – a unit of alternating current or electromagnetic wave frequency equal to one thousand hertz – to 300 gigahertz (GHz) – unit of alternating current or electromagnetic wave frequency equal to one thousand million hertz. 

The radiofrequency spectrum can be divided into bands, sometimes referred to as the microwave spectrum, ranging from very low frequency (3-30 kHz) to extremely high frequency (30-300 GHz). This spectrum is inversely proportional to the free space that these wavelengths can transmit, for example, very low frequencies can transmit between 10-33km distance whereas extremely high frequencies can only transmit 1-10mm.

 The advantage of this principle in medicine is that the energy generated in this way can be transmitted from such an antenna and applied directly to tissues, so that this energy can be directed and absorbed and even retransmitted for a variety of purposes. The major reason for using RF over other devices on the skin for rejuvenation is that it can be used to deliver heat energy to tissues non-specifically, unlike lasers, which depend on chromophores.1
