1. 980nm laser is the optimum absorption spectrum of Porphyrin vascular cells. Vascular cells absorb the-highenergy laser of 980nm wavelength, solidification occurs, and finally dissipated. 2. Compared with traditional method, 980nm diode laser can reduce redness, burning of the skin. It also has a less chance for scaring. To reach the target tissue more accurately, the laser energy is delivered by a professional design hand-piece. It enables energy to be focused onto a 0.2-0.5mm diameter range. 3. Laser can stimulate the dermal collagen growth while vascular treatment, increase epidermal thickness and density, so that the small blood vessels are no longer exposed, at the same time, the skin's elasticity and resistance is also significantly enhanced.
