Unless pale skin is accompanied by pale lips, tongue, palms of the hands, inside of the mouth, and lining of the eyes, it is probably not a serious condition, and does not require treatment.
General paleness affects the entire body. It is most easily seen on the face, lining of the eyes, inner mouth, and nails. Local paleness usually affects a single limb.
How easily paleness is diagnosed varies with skin color, and the thickness and amount of blood vessels in the tissue under the skin. Sometimes it is only a lightening of skin color. Paleness may be difficult to detect in a dark-skinned person -- and is detected only in the eye and mouth lining.
Paleness may be the result of decreased blood supply to the skin. It can also be due to decreased number of red blood cells (anemia). Paleness of the skin is not the same as loss of pigment from the skin. Paleness is related to blood flow in the skin rather than deposit of melanin in the skin.
Paleness can be caused by:
Normal fair complexion
Lack of exposure to the sun (it is healthier to be pale than tanned)
