Utilizing the explosive effect of the ND:YAG LASER, the laser permeate the epidermis into the dermis and takes effect on pigment mass and is absorbed by pigment. Since the laser pulses is extremely short in nanosecond and comes with super high energy, the pigment mass would swell quickly and break into small pieces, which will be eliminated through metabolism. In this case, the pigments become lighter gradually and finally disappear.

Thermal effect of Laser is utilized to cure telangiectasis (vascula). Laser irradiates on the abnormal vessels and the hemoglobin absorbs the Laser energy and solidifies and to achieve the purpose of vascular removal.
