About 90% of the skin's thickness is from the dermal layer of the skin, and much of the variation in skin thickness there is due to variations in collagen and elastin levels.ollagen and elastin break down with age. A gradual decrease in subcutaneous fat in the hypodermal layer of the skin also occurs with age, further decreasing skin thickness. Variations in thickness of these layers have the most dramatic effect on skin appearance.
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.
