Hello, I'm an expert in dermatology with a focus on skin conditions and their causes. A birthmark is a colored mark or blemish on the skin that is present at birth or appears shortly after birth. They are quite common and can vary in size, shape, and color.
Birthmarks are caused by the development of certain skin cells, specifically melanocytes, which are responsible for producing the pigment melanin that gives color to our skin, hair, and eyes. There are several types of birthmarks, including:
1. Vascular birthmarks: These are caused by the overgrowth of blood vessels and can be further classified into categories like hemangiomas and port-wine stains.
2. Pigmented birthmarks: These are due to an excess of melanin and include moles and café-au-lait spots.
The exact cause of why some people have birthmarks and others do not is not fully understood. It is believed that genetic factors may play a role, as well as environmental influences during pregnancy. However, most birthmarks are harmless and do not require treatment unless they are in a location that could cause functional problems or if they are at risk of becoming cancerous.

Vascular birthmarks - a red, pink, or purple blemish - are caused by abnormal blood vessels under the skin. Some people are born with pigmented birthmarks; these are usually brown and are caused by the clustering of pigment cells.
