Radiofrequency (RF) body contouring uses electromagnetic energy to heat tissue deep beneath the skin's surface for fat reduction and skin tightening. RF energy causes oscillation of molecules which generates heat between 3-6 electrodes, heating superficial and deep layers up to 20mm below the skin. This heat causes fat cells to release fatty acids and shrink, reducing fat and circumference while renewing collagen for skin tightening. Proper treatment raises the skin temperature to 40-42°C and monitors patient tolerance to achieve these effects safely and with minimal side effects.
