When the frequency of electromagnetic field is lower than 100kHz, it will be absorbed by the surface, and when it is higher than 100kHz, it can propagate in the air. Those high-frequency electromagnetic waves transmitted over a long distance are called radio frequency (RF). You should understand that radio frequency is not only used for beauty, but also for many communication systems, such as TV signals.
In fact, in a word:
Radio frequency can be seen everywhere in life.
So can rf beauty really resist aging? What is the principle?
Simply put, RF beauty is.
Using the penetrating power of radio frequency waves, it penetrates the skin to reach the dermis (or other sites of action), destroying the molecular structure in it and causing slight damage to cells, thus activating cell regeneration (especially the production of collagen).
