There are two main types of birthmarks; pigmented and vascular. Pigmented birthmarks are caused by the clustering of pigment cells and are usually brown, grey, bluish or black. They include moles, Café-au-Lait Spots and Mongolian Spots. On the other hand, vascular birthmarks are usually red, pink, purple or bluish in color, and are caused by abnormal blood or lymph vessels just below the skin’s surface. Vascular birthmarks generally do not fade away and include Macular Stains, Salmon Patches, Stork Bites, Angel Kisses, Port-Wine Stains and remnant Hemangiomas.
