SKIN TIGHTENING AND LIFTING (INTRAGEN) OVERVIEW
Volume loss, skin laxity and wrinkling are major findings associated with facial ageing. Skin laxity can also be caused by several heritable connective tissue disorders. In the ageing skin, acquired skin laxity seems to be a result of the combination of intrinsic and extrinsic processes. A major extrinsic factor is ultraviolet radiation (UVR), which can be potentiated by smoking. Monopolar radiofrequency (intragen) is one of the modes in which radiofrequency can be used in medicine and cosmetics to treat skin laxity.
Monopolar delivery is radiofrequeny for cosmetic rejuvenation is based on applying a single electrode to the treated area whereas the opposing electrode is relatively far removed so that the current goes deeply through the body. As a result, the tissue in the treated area is heated rather deeply (usually up to 20 mm) and intensely, which arguably increases both the potential benefits and risks. Monopolar radiofrequency is typically used to treat skin laxity and sag, usually of the face and neck.
