Radio frequency skin tightening is an aesthetic technique that uses energy to heat tissue and stimulate subdermal 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.

Radio frequency for volumetric dermal heating, aimed primarily at skin tightening treatments was awarded a CE Mark in June 2005 for cellulite reduction, and FDA approval for the treatment of wrinkles in April 2007, with further approval for more applications currently pending. Radio frequency uses mono-polar and bipolar devices which utilize one or two poles to conduct the RF energy.
