Another feature is added by allowing you to switch on 7 red/blue/green... light to support biochemical processes. Permanent automatic monitoring of ultrasound. Constant ultrasonic output by mains operation. Timer function. Double probes to create high-frequency oscillations that penetrate ultrasound, which acts on the human body to absorb the sound energy in heat, skin cells, promotes blood circulation in the skin, promotes metabolism, improves the absorption of nutrients and the body's defences, activates the cell and inhabits the bacte. (Important: the power supply. The pen must be connected to the socket via a power supply. Without wiring, it does not turn on, it needs a power source 10-15 minutes/time.
