How are red birthmarks formed on babies?

After the baby is born, he or she will have birthmarks on the body, which is normal. However, parents need to pay special attention to the color of the birthmark. If it is a red birthmark, it is likely to be a hemangioma. Therefore, parents should learn more about how the red birthmark on the baby's body is formed, and seek treatment as soon as possible if any problems arise.

1. Hemangioma. In the early stages, capillary hemangiomas in the human body look similar to red birthmarks, but most of them appear about half a month after birth and grow rapidly within 6 months after birth. It is 0.3 to 0.5 cm higher than the skin, purple in color, and gradually turns bright red, thus forming a birthmark. Cavernous hemangioma is an irregular tumor in size and shape, formed by dilated vascular sinuses and cavities filled with blood flow, and has a sponge-like appearance. It is not only seen on the skin, but can occur in organs throughout the body. Sometimes it is very large and deep into the subcutaneous tissue or muscle layer. The resulting birthmarks need to be treated early to avoid threatening your health. Among the causes of birthmarks, racemose hemangioma is formed by the communication between arteries and veins, which is a relatively rare cause.

2. Port-wine stain. This type of birthmark is flat and does not protrude from the skin, and fades when pressed with the fingers. When a child cries, feeds, or shouts, the subcutaneous plaques may become more obvious or reappear due to facial congestion and dilation of local capillaries. Port wine stains are related to family genetic factors. Generally speaking, it rarely expands, but except for a few that may disappear naturally, most of them will remain for life, and if they affect the appearance, they need treatment.

3. Since the health status of each person varies, some people may suffer from severe deficiency of trace elements such as zinc, copper, calcium, magnesium and phenylalanine and tyrosine in their serum, which may also cause birthmarks. People with birthmarks should eat more foods such as soybeans, mushrooms, and whole grains, and less alcohol, mutton, beef, and seafood. Frequent irritation of the affected area is also an important factor in the occurrence and development of birthmarks.

4. Melanin is produced by melanocytes and is the main factor causing skin color changes. The production of eumelanin depends on the supply of tyrosine and oxygen, the activity of tyrosinase, and the number of melanosomes produced.
