The yellow tint of the skin and eyes reflects the buildup of bilirubin in the body's tissues. Bilirubin is the yellow pigment in bile. The light helps break down the bilirubin into a water-soluble form so that the body can excrete it without conjugating it in the liver. Bilirubin (bil-ih-ROO-bin) is a yellowish pigment that is made during the breakdown of red blood cells. Unconjugated hyperbilirubinemia is usually a result of too much bilirubin presented to the conjugating machinery (from increased red blood cell destruction).
