Everybody is not born with a birthmark. More than 10 babies out of 100 have a birthmark when they are born or develop one shortly after birth.
Birthmarks can be different colors, shapes and sizes. The color can range from shades of red, pink, brown or blue. They can be flat or raised and are categorized according to characteristics. Common birthmarks include cafe-au-lait spots, hemangiomas and macular stains, according to the NYU Langone Medical Center. Birthmarks are commonly found on the face and neck but can form anywhere on the body. Birthmarks on the back of the neck are referred to as "stork bites," while those found on the forehead are often called "angel kisses." Most birthmarks fade over a period of months to a few years. Those formed on the back of the neck may not fade and do not require treatment.
