Radio frequency skin promotion system, also known as thermage beauty technology, of which the unique 0.25 ~ 47MHZ adjustable technology is applied. The BS-RF2 model chooses the best frequency range for cosmetic purpose with good treatment result as well as providing comfortable user experience. And make sure the transition between anodes to cathode is efficient, for the optimization of frequency. The skin organization resists the electrode changing action naturally; in this case, heating effect heats up the collagen and causes the denaturalization, which is called collagen shrinkage.
