Hydrolipoclasia is a treatment used to reduce cellulite and localised fat, as well as to shape different areas of the body, mainly the waist, abdomen, thighs and arms. This technique is meant to reduce fat and volume, but not to reduce weight. The application of this technique consists of two phases. The first one is the infiltration of a type of hypotonic serum in the area to be treated, causing a reaction of adipose tissue. Then, low-frequency ultrasound is applied using specific technology in the area to be treated. This generates bubbles which cause the breakdown of fat cells,and their subsequent elimination through natural metabolic ways.
