Monopolar radiofrequency tissue tightening

Abstract

Noninvasive tissue-tightening technologies rely on laser or radiofrequency (RF) energy to deliver heat to tissue without damaging the upper layers of the skin. This heating of the tissue results in mechanical and molecular changes to produce tightening of the skin. Immediately this heating produces collagen contraction, and then subsequent wound healing leads to new collagen production and wound contracture. The upper layer of skin is protected most frequently with a cooling mechanism or by utilizing low energy. There are currently multiple devices that claim noninvasive tissue tightening.
