Laser scar removal is to use the instantaneous high heat generated by the laser spot to sweep away the target in the scanning range, form the laser spot by changing the focusing characteristics of the laser, and complete the scanning by using the pattern generator. Laser scar removal uses composite color light, also called intense pulsed light (IPL), which is a kind of broad-spectrum visible light with special wavelength. Compared with pulsed laser, it has a softer photothermal effect. Composite color light scar removal is a new non-invasive skin medical beauty method based on composite color light technology, which can comprehensively improve and treat telangiectasia, various pigment spots, fine static wrinkles, large pores and so on. At the same time, improve skin texture and restore skin luster, softness and elasticity. Will not leave melanin.
