The yellowing of a circle around a woman’s mouth may be caused by a lack of trace elements, local inflammation, jaundice and other reasons. 1. Lack of trace elements: for example, the lack of zinc and vitamins in the female body may lead to yellowing around the lips. 2. Local inflammation: such as female patients with lipitis, often have a serious habit of licking the lips, feel dry around the lips, often unconsciously use the tongue to lick the upper and lower lips, which can lead to a circle of yellowing around the upper and lower lips. It may also be accompanied by dryness and cracking, and painful sensations. 3. Jaundice: For example, women with jaundice, which is usually caused by elevated levels of serum bilirubin due to diseases of the liver and biliary system, may also experience a ring of yellowing around the mouth. It is recommended that female patients with yellowing around the mouth, if the yellowing phenomenon is not relieved for a long time, should consult a doctor in time, under the guidance of the doctor to take targeted treatment.
