Moles, bumps, freckles, and warts appear on the skin from time to time. Birthmarks are those that develop in the first few years of life. While generally harmless, birthmarks sometimes alarm new parents, particularly when they appear in unexpected places such as the face. Understanding birthmarks can help ease this often-unwarranted fear.


1. How many types of birthmarks are there?

Birthmarks come in a variety of shapes, sizes, and colors, but there are two main types: pigmented and vascular. Pigmented birthmarks occur when skin contains more pigment than the surrounding area. Vascular birthmarks, on the other hand, form when the network of blood vessels in a particular area clumps together and becomes visible underneath the skin.
