It can be removed, and the best way to remove freckles is to remove them by laser. The treatment time of laser depigmentation is relatively short, only 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. Moreover, only diseased cells can absorb specific laser, and normal skin tissue will not be damaged, so laser depigmentation will not leave scars. You can take anti-inflammatory drugs for treatment and observation after operation. Be careful not to eat spicy food. Wish you good health.
