To say rf beauty, first briefly introduce what is rf. We all know the electromagnetic field, right? Current flowing through a conductor will produce a magnetic field, and alternating current produces an electromagnetic field.
The frequency of electromagnetic field is lower than 100kHz will be absorbed by the ground, higher than 100kHz can be propagated in the air. Those high-frequency electromagnetic waves with long-distance transmission are called Radio Frequency (RF). See here you should understand, the use of radio frequency can not only in the beauty of yo, a lot of communication systems are realized with the help of radio frequency, such as television signals.
In fact, summarized in one sentence:
Radio Frequency is everywhere in life
Radio Frequency beauty can really anti-aging? What is the principle of it?
Simply put, radiofrequency beauty is
the use of radiofrequency wave penetration, through the skin to reach the dermis (or other action sites), damage to the molecular structure of which the cells undergo a small damage, thus activating the cell newborn (especially the generation of collagen).
