Birthmark, medically known as mother spot or mole, is an abnormal proliferation of skin tissue and abnormal shape and color of skin surface during development. Before the popularization of skin laser, most birthmarks were frozen by electrocautery, and severe birthmarks had to be surgically removed and repaired, but they were easy to leave scars. At present, pigment spot laser can selectively destroy pigment, and dye laser can target vascular diseases without leaving scars after treatment. Therefore, apart from serious birthmarks, it is easy to leave scars.

The method of removing birthmarks is also related to the size, shape and position of birthmarks. Generally, small birthmarks do not need skin grafting, but if the area is large, skin flap method can be used in addition to skin grafting now, but the operation time is longer. The birthmark in delicate skin is not easy to remove, the scar is not easy to heal, and it is difficult to find the same delicate skin in other parts of the body after skin grafting.

Before skin laser was popularized, except birthmarks, most of them were frozen by electrocautery, and severe birthmarks had to be removed and repaired, but they were easy to leave scars. At present, pigment spot laser can selectively destroy pigment, and dye laser can target vascular lesions without leaving scars after treatment. Therefore, in addition to serious birthmarks, laser has become the best choice to remove birthmarks.

For the laser treatment of pigmented birthmarks, ultra-pulse laser is the best choice, and the current concept is that the earlier the treatment, the better. Take Ota master spot as an example. Generally, children need 3-5 times of treatment, while adults need 7- 10 times, so it is best to remove melanin before it accumulates. However, there are great differences in the treatment of birthmarks. Some people have obvious effects, and some people may have slow progress in treatment, so you should give yourself and your doctor more time to fully evaluate before receiving treatment.
