When the radio frequency current passes through the dermis of the skin tissue, the charged particles in the skin cells will resist the radio frequency wave, thus generating oscillations in the rapidly changing electromagnetic field and causing heat. When the heat in the dermis accumulates to a certain extent, it will destroy the existing collagen triple helix structure and cause the molecules to tighten, while the fibroblasts responsible for producing collagen molecules will produce new collagen molecules. With long-term use, the total amount of collagen in the dermis will increase, achieving the effect of wrinkle removal and tightening.
