What is the real cause of itchy lips?

The severity of lip itching depends on the cause. In many cases, lip itching is simply a small crack that is healing. This healing process will cause an itchy feeling, according to the health website Healthline (USA).

Another cause is chapped lips due to cold, dry air. This condition is very common during the winter months, when the air temperature drops. Chapped lips can cause an itchy feeling.

Medically, itchy lips are a manifestation of cheilitis. In addition to itching, cheilitis is also accompanied by a painful and burning sensation on the lips. Excessive exposure to sunlight, eczema or infection are all factors that can cause cheilitis.

In some cases, external factors such as allergens in certain products such as toothpaste, sunscreen or lipstick can also aggravate the symptoms of cheilitis. This is especially true when using products that contain fragrances to create a pleasant smell.

Similarly, cheilitis can also be caused by exposure to certain fresh fruits that can cause an allergic reaction and a tingling sensation on the lips. Highly acidic citrus fruits such as lemons, grapefruits, oranges, tangerines, and kumquats can all cause this effect on the lips. Cheilitis can also be caused by weather factors such as hot, dry winds and high temperatures.

Itchy lips can also occur with certain medications, infections, or health problems such as lupus, chronic hives, nutritional deficiencies, herpes simplex virus infection, or ingrown hairs.

If you have eliminated factors such as side effects of medication, illness, allergens, and weather, the cause may be the habit of biting or licking your lips. This condition is also known as traumatic cheilitis. Giving up these habits will help reduce inflammation and itching of the lips.

Itchy lips caused by an infection or illness can be treated with medication. If the cause is an allergy, identify the allergen and avoid it. Drinking enough water, keeping your bedroom humidified at night, and using lip balm can help reduce itchy lips, according to Healthline .
