Fractional laser is a new concept of medical optical skin care. It changes the mode of light emission, each pulsed laser emits a point of action that is composed of hundreds of micro-laser pulses, each micro-laser spot area is only tens of square nanometers. It is a minimally invasive treatment between invasive and non-invasive. With fractional laser treatment, the laser is applied to the skin in small, evenly spaced holes, causing a series of subsequent skin reactions to eliminate scars, tighten skin, rejuvenate skin and remove discoloration. Since there is intact skin between the tiny holes, the skin recovers quickly and can return to normal work life within a week after treatment. Therefore, fractional laser has the advantages of fast and significant effect of invasive treatment, and small side effects and short recovery time of non-invasive treatment.
