An abnormal buildup of blood vessels on or under the surface of the skin is called a hemangioma. In such a case, the skin may look like a red coloured birthmark and may protrude from the skin.
Red coloured birthmark of this kind frequently appear on the face, neck and behind the ears. They often look painful, but rarely cause any discomfort. Furthermore, they are usually small but can grow to be quite large. Sometimes they grow in internal organs such as the liver, larynx, or small and large intestines.
One of the most effective treatment for hemangioma is IPL Photofacial at Laser Genesis Skin Clinic.
