Laser freckle removal can help patients with pigmented spots realize their dream of freckle removal. Laser freckle removal has been very safe and effective after long-term practice. 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, and normal skin tissue will not be damaged, so laser depigmentation will not leave scars. During the operation, the subject will feel like a needle, and there is no need to use anesthetic drugs. Wish you good health.
