Principle The massager probe can create ultrasonic vibration at the speed of 1,000,000 times per second, which is most suitable for body care and can have effects on skin mainly in two ways: Mechanical and heat action (Physical) and chemical action.The ultrasonic vibration at the speed of 1,000,000 times per second can bring changes of volume and movement to every cell, thus have an effect of fine massager, which Is called cellular massager. Cellular massager can activate and adjust cell membrane, at the same time enhance the permeability of skin surface. Its heat action, physical and chemical action can increase the deep skin temperature by 0.5-1C, which can benefit for absorption of nutrition and medicine, accelerate metabolism and enhance the regeneration of fat and evacuation of tissue waste, repair lymph and capillary vessels, thus promoting body slimming.Furthermore, ultrasonic can introduce nutrients deep into skin. 3MHZ Ultrasonic Head Ultrasonic use of high frequency ultrasonic wave (1000000 / 3000000) shocks to promote human blood circulation and speed up metabolism.
