Jaundice is the medical term that describes yellowing of the skin and eyes. This condition forms when there is too much bilirubin in your system. Bilirubin is a yellow pigment that is formed by the breakdown of dead red blood cells in the liver.f you only have yellow skin, it’s more likely due to having too much beta-carotene in your system. Beta-carotene is an antioxidant found in carrots and pumpkins. An excess of this antioxidant is not a cause of jaundice.
