Comme l'énergie à haute fréquence peut être appliquée à une plus grande surface de la peau de façon continue grâce à l'utilisation d'une haute fréquence triphasée, il est possible d'améliorer l'effet de soin. De plus, il est possible de simplifier une structure et un fonctionnement du dispositif du fait de la suppression de l'unité de commutation de multiplexage compliquée.
