It is suggested that the laser speckle removal effect is better. 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. Moreover, only diseased cells can absorb specific laser, while normal skin tissues will not be damaged, and laser depigmentation will not leave scars.

Let's see what others say.
