Radio Frequency is an aesthetic technique that uses RF energy to heat tissue and stimulate sub-dermal collagen production in order to reduce the appearance of fine lines and loose skin. The technique induces tissue remodeling and production of new collagen and elastin. The process provides an alternative to facelift and other cosmetic surgeries. RF treatment also causes apoptosis of fat cells, which leads to fat layer reduction in the treated area.

By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat. Currently, the most common uses of RF-based devices are to non invasively manage and treat skin tightening of lax skin (including sagging jowls, abdomen, thighs, and arms), as well as wrinkle reduction, cellulite improvement, and body contouring.
