How is birthmark formed?

Birthmarks are abnormal hyperplasia of skin tissue during development, and then show an abnormal shape and color on the skin surface. Birthmark is mainly due to the serious lack of zinc, calcium, copper, magnesium and other trace elements in the serum of the human body, as well as phenylalanine and tyrosine, which seriously affects the biochemical process of pigment synthesis in the body, thus causing abnormal increase in pigment cells. These increased pigment cells will gradually spread through the epidermis through nerve transmission, thus forming pigmented plaques, that is, birthmarks.
