What exactly is the very popular radio frequency?

          Radio frequency (RF) is the abbreviation of Radio Frequency, which represents the electromagnetic frequency that can be radiated into space, and the frequency range is between 300kHz and 300GHz. Radio frequency is radio frequency current, referred to as RF, which is the abbreviation of high frequency alternating electromagnetic wave.


          When their frequency is higher than 100kHz, electromagnetic waves can be propagated in the air, forming long-distance transmission capabilities. Radio frequency is widely used in the field of wireless communication, which is closely related to our life and is everywhere.


          In recent years, with the development and maturity of radio frequency technology, it is more and more used in medical, beauty and other fields.


          When the radio frequency beauty instrument is working, the human body has become a part of the circuit, and the human body has impedance. When the radio frequency current encounters different parts of the human body, it will generate different heat due to the size of the impedance. The greater the impedance, the greater the heat. 


          The impedance of the muscle is about 100Ω, the impedance of the skin is about 300Ω, and the impedance of the fat is above 2000Ω. In theory, the application of radio frequency to fat-dissolving will have a more significant effect.


          When the target is set to the connective tissue in the middle layer of the dermis, the radio frequency will form an electromagnetic field under the skin, which will act on the water molecules in the collagen, causing the water molecules to vibrate and rotate at a speed of millions of times per second to generate heat. When the temperature reaches 55-70°, the collagen fibers shrink and tighten, the face is lifted obviously, and the skin becomes tight.


          When the target is set to the deep layer of the dermis, it will stimulate the collagen fibers to shrink immediately, and a series of physical reactions will be produced after the tissue is heated, which will enhance the metabolism of the new morning, so that the fibroblasts in the dermis layer will continuously synthesize new collagen and synthesize elasticity. Hard protein, secretes base fluid, so that the skin restores its original elasticity and becomes plump and smooth again.


          When the target is set to the subcutaneous tissue layer, the fat cells in the subcutaneous tissue layer will be heated to reduce the volume, so as to achieve the effect of weight loss.


          After radiofrequency acts on the organism, it can lead to vasodilation, accelerated blood and lymph circulation, increased capillary and cell membrane permeability, increased intracellular enzyme activity, and accelerated metabolism.
