The pressure wave through deep massage reduces the tissue oedema which is one of the initial phenomena of the Cellulite. Reduction of oedema causes less puffiness of the skin. In addition, due to the oedema, there is an elevation of toxins in the skin tissue which induces degeneration of collagen fibers that hold the fatty chambers. By reducing the toxins, through reduction of oedema, there is less damage to the collagen fibers, thus, less degeneration and tighter holding of the skin. Moreover, there is evidence of enhanced collagen synthesis as a result of acoustic wave treatments.
