EMS Muscle Stimulator: Adopting EMS technology to continuously expand and contract muscles and deeply remodel the internal structure of muscles. It can boost the generation of new proteins and muscle fibers, thereby increasing muscle density and volume.
Roller: This device is designed to make the ball rotate 360 degrees along its axis. As the ball roller applies pressure to the skin, it creates a ‘pulsating compression’ effect that tightly pulls the skin tissue without squeezing or damaging it.
