You may have noticed that your lips turn purple or blue in the cold, or you may have seen a baby, an elderly person or someone else with bluish or purplish lips. In many cases, this type is caused by cyanosis, which is a discoloration of a part of the body resulting from a lack of oxygen in the blood.
A thyroid disease and psoriosis can also cause dryness of the lips. Perleche, or angular cheilitis, can cause dryness around the mouth as can diabetes. Those with Downâs syndrome commonly have dry, chapped lips as do those with actinic cheilitis, which is caused from too much sun exposure.
