These marks can be red, pink, brown, tan or blue. There is no way to prevent birthmarks. They are not inherited, and very little is known about how they occur. Most are benign and fade in early childhood. Some birthmarks, however, may be more dramatic and cause cosmetic problems, or even be precursors to cancer.
Red birthmarks can range from tiny, pink dots to large, deep-red marks.
Red birthmarks are caused by blood vessels very close to the surface of the skin, and are also called vascular birthmarks . Macular birthmarks or stains are sometimes known as stork bites or angel's kisses . These tiny, pink marks are most often found on the forehead, eyelids and back of the neck. They require no treatment and usually fade as the baby grows. Hemangiomas , known as strawberry birthmarks , are also very common.
