There are many birthmarks in the hospital. What kind of birthmark are you? I have a birthmark in Zhengzhou, and I can give you some advice. The child has a nevus of OTA on his face, which has not been treated for a long time. I thought it would be bigger, but it's getting bigger. Other parents should pay attention to the birthmark or get it as soon as possible, and don't wait until the birthmark is big to affect their children. I saw it on the 7th floor of yiguang No.2 Middle School, next to the Erqi District Road Railway Station. I wish you a speedy recovery!
