Now I'd like to introduce to you how birthmarks are formed.

How is birthmark formed

Reason 1: during the embryonic development, especially in the early stage of vascular tissue differentiation, the red birthmark developed into a red birthmark due to the small-scale dislocation of its control gene segment.

Reason 2: according to the observation, the incidence of red birthmark in girls is higher than that in boys. 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.

Cause 3: the cause of formation of red birthmark the cause of long red birthmark is due to the lack of nerves dominating 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 deepens with age, turns into bright red and purple, and thickens into nodules.
