RF (radio frequency) is a kind of electromagnetic wave that changes more than 10,000 times per second. Electromagnetic waves of different frequencies can cause different stimulation effects on the treated skin.
For example, 1-10MHz electromagnetic wave can penetrate the skin surface, heating the collagen fiber in the dermis layer to 55℃~65℃. The collagen fiber will shrink after absorbing the heat, which strains the formal skin and puts it in a healthier and more energetic state.
13.56MHz ultrahigh-frequency electromagnetic wave can be absorbed by hemoglobin and breaks it down. Therefore, it is widely used in rosacea treatment.
