These birthmarks may be born, or they may appear shortly after birth or many years later. If left untreated, it will not disappear on its own, and sometimes it will change and develop. The lesion is located in the skin and deep, so it is difficult to remove it by conventional methods. If the treatment is too shallow, the lesion cannot be removed, and if you want to reach the ideal depth of treatment, you will leave scars. The laser therapy machine in Plastic Laser Center can treat coffee spots safely and selectively, and it is fully computer controlled. The emitted laser can penetrate the epidermis, reach the lesion site, be selectively absorbed by the lesion pigment particles, be destroyed by the photothermal decomposition of the laser, and be destroyed by phagocytes in the body. Normal skin and tissues are not affected, and the skin is not damaged after treatment, leaving no scars. It is the safest and most effective treatment for pigmented nevus at present. There are some rare genetic or chromosomal diseases in clinic that can also cause coffee and milk spots. Therefore, when children are found to have coffee milk spots with dysplasia or other physical abnormalities, they should go to the hospital for examination in time.
