Birthmarks or ‘naevus’ are colored marks found on a newborn baby’s skin. The mark can occur in many different colors such as blue, blue-gray, tan, brown, black, pink, white, red and purple. They come in many different shapes and sizes. They can be smooth and flat or are raised above the skin surface.
The causes of birthmarks are not yet proven by science. Many experts are of the opinion that the birthmarks are inherited from parents or other family members. The other reason given is due to the overgrowth of blood vessels. The following are some of the common type of birthmarks.
