Please do laser cosmetic radiation?

Analysis: laser in essence and ordinary light, but because of the laser's high monochromatic brightness characteristics of the human body's mechanism, the role of the object, the role of the form and the role of the target is not the same, the reason is because of the different wavelengths, different dosages of laser light on different human tissues can produce different types of reactions to the level of the biological effects of laser. Laser biological mechanism of action including the intensity of the biological effects caused by photoluminescence, heat, pressure, chemical effects, electromagnetic fields and biostimulation. Advice: So the laser radiation damage to the human body is mainly photothermal, light pressure, photochemical damage to the eyes and skin.
