Why do babies have birthmarks after birth

Factor 1: in the process of embryonic development, especially in the early stage of vascular tissue differentiation, due to the small-scale dislocation of its control gene segment, the tissue differentiation of specific parts is abnormal, and the development of the baby's birthmark. If the embryo in the process of development, because of the influence of the environment, it will also lead to the child has a birthmark.

Factor 2: according to the observation, the incidence rate of girl with baby birthmark is higher than that of boy. The level of estradiol in hemangioma tissue is higher. Estradiol is an estrogen in human body, which indicates that it is related to the level of estrogen. Generally speaking, most girls have birthmarks, while few boys do.

Factor 3: the reason for the birthmark of a long baby is the lack of nerves that dominate the blood vessels at the lesion site, which makes the capillaries dilate and congest. At first, it appears as red or pink patches. Later, it can deepen with age, turn into bright red and purple, and thicken into nodules. In clinical medicine, this kind of person is relatively rare, generally speaking will not appear.
