Xanthelasma is a sharply demarcated yellowish deposit of cholesterol underneath the skin.  It usually occurs on or around the eyelids ( xanthelasma palpebrarum , abbreviated XP).   While they are neither harmful to the skin nor painful , these minor growths may be disfiguring and can be removed.  There is no high-quality evidence that xanthelasma deposits are related to blood low-density lipoprotein levels or increased risk of atherosclerosis .
