Working principle of 980NM Diode Laser Therapy Machine: 980nm laser is the optimum absorption spectrum of porphyrin vascular cells. Vascular cells absorb the high-energy laser of 980nm wavelength, solidification occurs, and finally decomposed by phagocytes, excluded in vitro. Compared with the traditional method, 980nm diode laser can reduce redness, burning of the skin and scar. Besides, 980nm laser can stimulate the dermal collagen growth while vascular treatment increases epidermal thickness and density so that the small blood vessels are no longer exposed. As well as the skin's elasticity and resistance are significantly enhanced. To reach the target tissue more accurately, the laser energy is delivered by a professional design hand-piece. Assist with infrared ray 635nm, it enables energy to be focused. As the technology matures, it is not limited to vascular treatment, but can also be applied in the fields of dentistry, gynecology, physiotherapy, etc.
