[Microfocussed vs. macrofocussed ultrasound for body contouring].

Focussed ultrasound is capable of heating tissue in small microscopic areas up to 65-70 °C and is a technique that can be used not only for destruction of superficial tissue but also for fat reduction. The focussing of sound waves according to the principle of a bundling of rays is carried out without injury to the skin. The penetration depth of the coagulation depends on the wavelength. Wavelengths that reach penetration depths of 6mm, 9mm and even 13mm and therefore deeper layers of the dermis and fat tissue are new. These enable fat cells to be eliminated and ultimately lead to girth reduction and also additionally to tightening. The effectiveness has been confirmed by several studies.
