[0002] Radio frequency beauty uses radio waves emitted by a radio frequency treatment device into the subcutaneous tissue, causing the natural resistance of the subcutaneous tissue to move and generate heat energy. It uses the principle that the collagen fibers in the dermis will immediately contract at 55-70°C. While the collagen contracts immediately, it also stimulates the dermis to secrete more new collagen fibers for regeneration, thereby supporting the skin's support again, increasing the thickness and density of the dermis, smoothing wrinkles, and improving sagging.

[0003] Currently, the use of non-invasive radio frequency beauty therapy devices requires personnel to hold the end that emits radio waves and move it back and forth on the human skin. This method not only fails to free the staff's hands, but also the labor intensity of the back and forth movement is high, which undoubtedly increases the workload of the staff.
