Where do birthmarks come from?
“It is not clear why some children have birthmarks and others do not. Some birthmarks appear because a child has extra color (pigment) in his or her skin. Other birthmarks appear because a child’s blood vessels did not develop normally or are grouped together too closely. Many folktales and myths exist about the causes of birthmarks, but none has been proven to explain the true causes of birthmarks.” http://www.peacehealth.org/kbase/topic/m… “A birthmark is a blemish on the skin formed before birth. They are part of the group of skin lesions known as naevi. The cause of birthmarks is unknown.” http://en.wikipedia.
