What is the Cause of Birthmarks?
Birthmarks are colored marks on our skin which are present at birth or appear shortly afterwards.
Birthmarks are of two types, vascular and pigmented.
Vascular birthmarks are caused when a lot of blood vessels clump together or they are stretched wider than usual.
Pigmented birthmarks are generally caused when cells called melanocytes grow together in clusters.
Birthmarks may also be inherited sometimes and some of them may be similar to marks on other family members.
