The "bruising" on newborn babies is not really bruising, but a normal skin phenomenon called "congenital dermal melanocytosis", also called "Mongolian spot". Simply speaking, it is a kind of birthmark, which is a pigmented skin abnormality after birth. Generally speaking, the color of the plaque will gradually become lighter or even disappear from Qing Wu, and rarely last until adulthood.
The reason for this phenomenon is that melanin accumulates and deposits under children's skin, forming "bruises", which is also commonly known as Mongolian spots. However, parents need not worry. Usually this Mongolian spot will gradually disappear after the baby grows up. Parents don't have to interfere and worry too much.
Congenital dermal melanocytosis refers to the aggregation and deposition of melanocytes in dermis. When the baby is still in the embryonic state, melanocytes move from neural crest to epidermis and fail to penetrate the interface between epidermis and dermis, so that melanocytes are "trapped" in the deep dermis, thus forming. This is a genetic disease that appears on the skin. Harmless to human body, it will fade after a few years.
The answer to many newborn babies' buttocks "bruises" has come out, so parents don't have to worry too much. Even if a small part of Mongolian spots are ectopic, they will appear in the obvious parts of children. Parents should also keep abreast of their children's inner needs. If he feels depressed, pushed out by his classmates and feels inferior, he must not be afraid to waste time and money and go to the skin hospital for treatment as soon as possible. Children's physical health and mental health are issues that parents should pay attention to. Generally speaking, Mongolian spots will not cause much problem. With the increase of age, Mongolian spots will gradually disappear. However, it should be noted that some people have Mongolian spots on their faces or necks, which makes children feel a little inferior at an early age and will also affect their physical and mental health. This kind of situation can be treated in dermatology or plastic surgery hospital as soon as possible.
