How does the newborn see if she has a birthmark

summary

I feel that when my grandfather lost his birthmark, his grandmother would be afraid to see his son's face when he grew up. Later, I took him to the hospital for laser surgery, and now there is no birthmark. Let's talk about how a newborn sees whether she has a birthmark.

How does the newborn see if she has a birthmark

The first aspect: genetic factors are generally considered to be the main factors causing the formation of birthmarks, but so far there is no solid scientific basis. Some biologists believe that the formation of birthmarks is due to the mutation of chromosomes in human evolution.

Second, environmental pollution, such as the abuse of pesticides, is one of the main causes of birthmarks.

The third aspect: malnutrition, fetal lack of certain nutrients, such as calcium, iron, zinc, magnesium and other trace elements and phenylalanine, tyrosine and so on, are easy to affect the biochemical process of pigment synthesis, resulting in abnormal increase of pigment secretion by pigment cells, and through nerve conduction to the epidermis, and gradually spread to form a birthmark.

matters needing attention

Birthmarks are congenital diseases, but some environmental and human factors are the predisposing factors that affect the incidence rate of this disease. Birthmark can be divided into pigmented birthmark and vascular birthmark. Pigmented birthmark refers to the increase of pigment deposition in epidermis or dermis, while vascular birthmark refers to the expansion and deformity of dermis or subcutaneous blood vessels.
