Ultrasound technology is used to efficaciously fightcellulite, localized adiposity, skin orange peel andcirculatory problems in medical-aesthetic field. Thetreatment is based on biological effects caused byultrasonic waves whose frequency is over 30 KHZ (i.e. 30.000 vibrations each second). These wavesgenerate an acceleration of serum diffusion processthrough cellular membranes: by reducing the viscosityof intra and extra cellular colloidal substances andtransforming a part of mechanic energy into thermalenergy. The thermal level augmentation generates acellular metabolism increase as well as a temporaryvasodilatation, by facilitating fat and intercellularliquids removal.
