beauty and health back pain relief physical therapy 405nm 635nm cold laser therapy device machine

980nm diode laser is the optimum absorption spectrum of porphyrin vascular cells. vascular cells absorb the high-energy laser of 980nm wavelength, solidification occurs, and finally dissipated. to overcome the traditional laser treatment redness large area of burning the skin, professional design hand-piece, enabling the 980nm diode laser beam is focused onto a 0.2-0.5mm diameter range, in order to enable more focused energy to reach the target tissue aser can stimulate the dermal collagen growth while vascular treatment, increase epidermal thickness and density, so that the small blood vessels are no longer exposed.syi
