RF CO2 Fractional Laser System fires a laser beam through RF CO2 Tube which is then split into numbers of microscopic beams, producing tinier dot than general CO2 laser, or pixel-like treatment zones within the selected target area of the skin, leaving the other zones within it perfectly intact. Therefore, the heat of laser only passes deeply through the factional damaged area. This allows the skin to heal much faster than if the whole area was treated. During the skin self-resurfacing, a great amount of collagen is produced for skin rejuvenation, eventually the skin will look much healthier and younger.
