You can choose laser to remove pigment spots, and the treatment time is relatively short, which is about ten minutes at most. After each treatment, the skin should be given a metabolic process. Therefore, the interval of laser pigmentation treatment is usually 3 months. The principle of laser speckle removal is that different types of lasers produce different colors of light, and the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Therefore, the shaping mechanism uses a laser instrument to generate a high-intensity beam to make the pigment fade, so as to achieve the purpose of removing pigment spots.
