Monopolar radiofrequency (RF) is a nonsurgical approach to skin tightening and photorejuvenation. The FDA first cleared its use for treatment of periorbital rhytids in 2002. Additional clearances were given for tightening of the lower face in 2004 and for skin tightening on the body in 2005.
Monopolar radiofrequency (MRF) for facial rejuvenation works by diffusely heating the dermis and subdermal fibro-septal network. Immediate collagen contraction and long-term neo-collagenesis produce antiaging effects.
