Are birthmarks hereditary? These things need to be understood

Many children are born with birthmarks, and they may even change as the child grows. Many people want to know if birthmarks are hereditary. In fact, birthmarks are not hereditary diseases. They are a type of hemangioma, which may have a lot to do with a woman's development during pregnancy.

1. The birthmark is a maternal spot

Birthmarks are medically called "mother spots". They are abnormal proliferation of skin tissue during development, resulting in abnormal shapes and colors on the skin surface. Birthmarks are very common, occurring in about 10% of newborns. According to experts, birthmarks may be discovered at birth, or they may gradually emerge a few months after birth. Birthmarks can generally be divided into pigmented and vascular types. Common pigmented types include Ota's nevus, congenital melanocytic nevus, cafe au lait spots, etc., while vascular types include port-wine stains, strawberry hemangiomas, etc.

2. Are birthmarks hereditary?

Some people worry that birthmarks will be passed on to the next generation, thus affecting their love and marriage. Birthmarks are not hereditary diseases, so it is unlikely that they will be passed down from generation to generation, and patients do not need to worry about it. It can be seen that birthmarks are a very common skin symptom and there is no genetic factor, so parents don’t have to worry. If you want to get rid of the trouble of birthmarks, you can choose laser therapy to remove it. This operation is very simple and has no harm to the body. Experts recommend that birthmarks be removed as early as possible.

3. How are birthmarks formed?

A birthmark is an abnormal growth of skin tissue during development, which causes abnormal shapes and colors to appear on the skin surface. It is mainly due to the severe deficiency of trace elements such as zinc, copper, calcium, magnesium and phenylalanine and tyrosine in human serum, which affects the biochemical process of pigment synthesis, leading to an abnormal increase in pigment cells, which gradually spread to the epidermis through nerve conduction to form plaques; but birthmarks with neat edges spread more slowly.

The most common birthmarks on babies are stork bites on the back of the neck and eyelids. They are caused by the dilation of blood vessels and will gradually disappear within the first year. About 10% of newborns develop a strawberry birthmark - a raised, red, dot-like birthmark - in the first four weeks of life; it usually disappears within two years.
