the 6.78MHZ radio frequency penetrates the epidermis directly into the Dermis with a sine wave output.  Ultra-pulse shock wave technology Generates high-energy focused ultrasound, rapidly penetrates the epidermis, fat Layer, stimulates the membrane contraction of the SMAS layer, instantly makes the skin tissue reach 65°C, thus producing a thermal coagulation effect on the Skin, forming a mesh coagulation point in the dermis and fascia layer
