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.

Ruby laser is the best choice for laser treatment of pigmented birthmarks. At present, the idea is that the earlier the treatment, the better. Take Ota master spot as an example. Generally, children need 4-5 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.

Vascular birthmarks are generally treated with dye laser, but the effect and reaction are difficult to predict. For example, the blood vessels stained with wine can be removed by laser, and the effect is most obvious when the ratio of 1 and 2 times, which can reach 50-60%. After that, the therapeutic effect will decrease because the residual blood vessels become deeper and deeper, and usually as many as 7- 10 treatments are needed. Because of the deep tissue depth, strawberry hemangioma can only dredge superficial blood vessels by using laser as auxiliary treatment. Generally, sclerosing agent or steroid injection is needed, and even vascular embolization and surgical resection are needed. The traditional idea is that strawberry hemangioma will naturally shrink without treatment, but the result of delaying treatment is that the hemangioma shrinks incompletely, leaving ugly scars. Therefore, the current concept is to recommend early treatment, even at the age of 6 months.
