The role of the RF beauty instrument is to directly penetrate the skin by using RF waves. Besides, using the impedance of skin, RF waves also allow the cells to produce intense resonance rotation (millions of times per second) to generate heat for collagen tissue heating and fat cell heating, causing the temperature of the lower layer of the skin to rise instantly. According to the principle that stimulation with the dermis produces immediate collagen tightening and regeneration, which achieves the effect of face lifting and wrinkle reducing. After treatment, collagen will gradually proliferate and reform, so that the sagging or loose skin can be lifted and tightened.
