The main role of low-energy laser bio-stimulation (Bio stimulation) is to provide appropriate energy to stimulate biological cells and induce or strengthen a number of physiological responses, including promoting local blood circulation, regulating cell function, enhancing immune function, and promoting cell metabolism and proliferation. Wavelength of 650nm-660nm red laser just in human eye color of the visible spectrum, so we can see the red light 650nm -660nm can penetrate the organization up to 8-10mm, effectively activate and repair cells, stimulate the synthesis of cell metabolism, for the superficial cells biochemical stimulation and hyperemia. Irradiation of meridian points stimulates the meridian points related organizations, the skin tissue will not cause harm exempting patients' fear of needles, and also has the function to healthily stimulate the meridians.
