More than 80 percent of babies have some kind of birthmark which may be fade away over time, while some last for life. Most birthmarks fall into one of two categories: vascular or pigmented.

Vascular birthmarks are caused by blood vessels below the surface of the skin. They range in color from pink to red to bluish, depending on the depth of the blood vessels.

Pigmented birthmarks—usually brown, gray, bluish, or black—result from an abnormal development of pigment cells.

Some of the birthmarks such as hemangioma pushing on the eye may require early removal. The decision for removal can be made later because some of this birthmarks fade on their own without causing any physical problems.

Pigmented birthmarks such as Nevus of Ota or Cafe-au-lait however usually grow bigger in size as the child grow up.

If you have any birthmark, consult the dermatology doctor.
