What Causes Birthmarks

Birthmarks, medically termed 'naevus', are colored marks found on or under a newborn baby's skin. The mark can occur in different colors, including blue or blue-gray, brown, tan, black, pink, white, red and purple, varying in size and shape. The marks can either be smooth and flat or raised from the surface of the skin. Some of the birthmarks may fade away after the child reaches a certain age, while others may tend to grow in size, as he/she becomes older. Though harmless in nature, people still want to know what causes birth marks and look for ways to get rid of them.
