Radiofrequency waves are electromagnetic waves, which transform electrical energy into heat once administered to the dermis. Fractional radiofrequency consists of causing a multitude of temporary micro-injuries, by generating heating in the dermis. This increase in subcutaneous temperature makes it possible to generate significant collagen stimulation.
Fractional radiofrequency a technique that is similar to fractional rejuvenation lasers. Its principle consists of causing numerous temporary micro-injuries (by heating) in the dermis in order to generate significant collagen stimulation. The treatment applicator is made up of a multitude of current starting points (pins). Since the heated depth of the skin is approximately half the distance between the source electrodes, the applicator varies the two origins continuously in order to heat as many depths as possible. This is not possible with bi/multipolar radiofrequency, with which the heated depth is constant.
