Why do people have birthmarks and how are birthmarks formed? Birthmarks are formed from the beginning of a baby , so what are the reasons for the formation of birthmarks? Let's take a look!

Why are there birthmarks

Baby birthmark formation

1. Long birthmarks in babies are generally due to the serious lack of trace elements such as zinc, copper, calcium, magnesium and phenylalanine and tyrosine in the serum, which affect the biochemical process of pigment synthesis, resulting in an abnormal increase in the secretion of pigment by pigment cells. A plaque that gradually spreads through the epidermis caused by neurotransmission.

2. The pigment type in baby's long birthmark is usually formed by the accumulation of special pigment in cells in the dermis. As the child grows older, the pigment deposited by cells in the dermis gradually decreases. At about 2 years old, most of these birthmarks disappear completely, and a few pigment spots can be partially retained for life.

3. A baby's long birthmark is an abnormal growth of skin tissue during development, and abnormal shapes and colors appear on the surface of the skin. Baby birthmarks can be found at birth, or they may slowly emerge only a few months after birth. Baby birthmarks can generally be divided into pigmented and vascular types.

4. Vascular birthmarks are derived from capillaries remaining in the embryonic period, and most of them exist at birth. Hemangiomas are not real tumors. There are many types and different manifestations. The natural process of vascular type goes through three periods of growth, stasis, and subsidence.

5. When the fetus develops and grows, it is formed by the excessive proliferation of certain normal tissues. According to the research of relevant experts, the pigment cells of the birthmark begin to appear when the birthmark is 4-5 months old, and the birthmark is born. It disappears gradually within 1 to 2 years; but there are also a very small number of people who still have birthmark pigment spots when they reach adulthood.

Everyone has figured out the reasons for the formation of birthmarks, and it must be possible to prevent them. Once a birthmark appears, don't let it grow, but actively seek treatment. At present, laser treatment of birthmarks is good and can be the first choice for babies.

Causes of birthmark formation

1. External environment: The most environmental pollution is one of the main reasons for birthmarks. After the human body is stimulated by the external pollution environment, it will show different ways of expression, and birthmarks are one kind.

2. Living environment: Mainly refers to the acquired environment. Due to some bad problems of personal lifestyle, such as long-term irregular eating, irregular personal life and uncontrolled overeating, it may be intensified under certain conditions. The body, thereby forming a birthmark.

3. Genetic factors: Although this factor is generally considered to be the main factor that causes birthmark formation, there is no conclusive scientific basis so far. There are also biologists who believe that the formation of birthmarks is caused by chromosomal mutations in human evolution, which is then reflected by heredity On human skin.

4. Malnutrition: Due to the lack of certain nutrients such as calcium, iron, zinc, magnesium and other trace elements, phenylalanine, tyrosine, etc., the human body easily affects the biochemical process of pigment synthesis, resulting in abnormal pigment secretion by pigment cells It increases, and is transmitted to the epidermis through nerves, and gradually spreads, and birthmarks will be formed.

Causes of black birthmarks

1. Micro-substance factors in the body: due to the serious lack of trace elements such as zinc, copper, calcium, magnesium and phenylalanine and tyrosine in human serum. Patients with black birthmarks should eat more foods such as soybeans, mushrooms and whole grains, and less foods such as alcohol, lamb, beef and seafood.

2. Melanocyte factors: The pathogenesis of black birthmark formation: Melanin is produced by melanocytes and is the main factor that causes skin color changes. The production of eumelanin depends on the supply of tyrosine and oxygen, the activity of tyrosinase and the production of melanosomes.

3. Ultraviolet rays: Under normal circumstances, ultraviolet rays can activate melanocytes, which is manifested as an increase in melanocytes per unit area, strong melanin production and faster movement. Therefore, ultraviolet rays are the driving force for melanocytes to produce melanin. However, the response of melanocytes to ultraviolet light varies with the wavelength, which promotes the formation of melanosomes and forms black birthmarks.

4. External factors: Black birthmarks appear on the skin. Frequent irritation of the affected area is also an important factor in the development of black birthmarks. Therefore, it is necessary to avoid irritation of the affected area of ​​the black birthmark and do a good job of protection.
