Q:The difference between an ultrasonic knife, Germagi, and radio frequency

Ultrasonic knife: 4.5mm probe directly acts on the deep layer of the muscle layer of the skin, precisely positioning, energy focused on one point, so that the muscle layer of the largest extent of the contraction. The 3.0mm probe focuses energy directly into the dermis 3.0mm, and there is no energy decay during the process.Germagi: when acting on the skin, the energy is transmitted through the epidermis to the deeper dermis, which is from the outside to the inside because it is heated in large areas rather than focused, so the energy is constantly attenuated during conduction.Radio frequency wrinkle is a probe to touch the skin, the radio wave energy transmitted to the skin deep. This deep balanced heating can promote the skin structure and subcutaneous tissue to stretch immediately, and there is no energy decay during the process.
