Monopolar RF takes that epidermis balances normal temperature, RF electric wave produces heat into deep skin as nuclear technique, based on assortments of skin comfortable, harmless, it uses RF electric wave to produce heat exchange, precisely attains skin deep, stimulates inner ion of body, colloid granule with electricity will be forced rapid movement, vibration or attrition, then produce heat energy. As same time, under effect of polarized molecule resonance, it heats collagen tissue of dermis layer. When deep collagen tissue is heated up to 45°- 60°C, it will naturally produce instant shrinking, stimulate protein, and make them rear ray, rebuilt skin soft bracket, finally get tight skin, remove wrinkle, recover skin elasticity and luster.
