Radiofrequency (RF) devices are commonly used in skin care and medical practices for skin tightening, body contouring, hair removal, minor skin imperfections, and much more. Radiofrequency waves are a form of radiation, which is the release of energy in the form of electromagnetic waves. These waves can be classified as low or high energy depending on the amount of energy dispersed.

The Federal Communications Commission (FCC) regulates radiofrequency devices under the category of electronic-electric products or devices that are capable of emitting radiofrequency energy by radiation, conduction, or other means. It should be noted that nearly all electronic or electric devices are capable of emitting radiofrequency energy, even cell phones or an FM radio.
