The cryolipolysis utilizes the increased sensitivity to cold of fetal cells compared to the surrounding tissue. A non-invasive applicator is applied to the desired area and cools the underlying fatty tissue, the tissue being cooled down to -9 degrees. A special nonwoven fabric with anti-freezing gel, which lies between the tissue and the applicator, reliably prevents frostbite. The fat cells thus cooled pass through the so-called apoptosis (controlled cell death) and are subsequently degraded by the body. This reduces the thickness of the grease layer. During the treatment, sensors contained in the applicator ensure a uniform, consistent temperature. These sensors are connected to the control console and enable continuous monitoring and adjustment of the cooling during the cryolipolysis process. In addition, the tissue is repeatedly massaged during the treatment by means of variable suction on the skin. The fetal cells die and activate inflammatory cells by means of messengers, which gradually degrade the affected fetal cells in weeks and months.
