This treatment is based on lowering tissues temperature. The aim of cryotherapy is to decrease the temperature of skin and deeper tissues, resulting in deep hyperaemia at the site of procedure. Cryotherapy has mainly an analgesic and hyperaemic effect. Low temperature causes superficial vessels to constrict, which leads to increase in diameter of deep vessels. Thanks to this mechanism hyperaemia of deeper structures is achieved. This condition lasts in this area for about 4 hours.
