    *BIRTHMARKS ARE GODS STAMP OF APPROVAL!!!

    Birthmarks are colored skin spots that either are present at birth or develop shortly after birth. Birthmarks can be many different colors, including brown, tan, black, pale blue, pink, white, red, or purple. Some birthmarks are only colorations of the surface of the skin; others are raised above the surface of the skin or extend into the tissues under the skin. Most are types of moles.
    A birthmark (also known as nevus) is a result of a development abnormality of the skin. This leads to proliferation of blood vessels or abnormal pigmentation in the dermal and epidermal structures of the skin, resulting in birthmarks. Birthmarks are perceived to be non-hereditary. In addition, twice as many females as males are observed to have various forms of birthmarks. However, scientists have not yet come up with an explanation for these phenomena.


    Birthmarks fall in to two main categories, vascular birthmarks, and pigmented birthmarks. Vascular birthmarks are made of the abnormal proliferation of tiny blood vessels and related to vascular skin changes. They are rarely fully-grown at birth.Hemangiomas observed to be more common among females than males, with 5 times as much females having hemangioma. Another interesting fact is that hemangiomas occur predominately in Caucasian people as opposed to dark skinned people. It has also been noted that low birth weight infants of less than 2.2 pounds have a 26% chance of being born with or developing a hemangioma shortly after.
