1ULTRASOUND WAVES: The high level frequency vibrations convert sound energy into heat, gently massaging skin cells to promote microcirculation, improve blood flow, accelerate metabolism, enhance nutrient absorption. 2NO SIDE EFFECTS: Ultrasound massage falls under normal massage, known for its mature technology, reliable effectiveness, non invasiveness, no radiation, and no side effects. 3MULTIFUNCTIONAL: Ultrasound vibrations improve cell movement, providing massage and soreness relief. It enhances metabolism, improves blood and lymphatic circulation, alters protein synthesis speed, and increases regenerative functions. 4ENHANCED ABSORPTION: Ultrasound waves facilitate emulsification of liquids and liquefaction of gels, allowing skincare products to penetrate and absorb into the skin, promoting skin metabolism. 5SIMPLE AND SAFE: The ultrasound machine features touch controls with clear and understandable buttons and instructions, offering 3 adjustable strength levels, 2 working modes, and 6 time settings, with indicator lights. 6WIDE APPLICATIONS: Ultrasound vibration massager is suitable for neck, back, legs, feet, and eye area, promoting muscle relaxation, reducing fine lines around the eyes, assisting in activating eye cells, accelerating eye serum absorption, and improving eye blood flow and circulation to reduce under eye dark circles.
