Published: Last Updated on

Cheilosis is a lesion of the lips and mouth caused by the formation of scales and fissures due to a riboflavin deficiency. In general, this deficiency derives from an inadequate diet and, in severe cases, it can cause bleeding when opening the mouth and cause ulcers. It should not be confused with angular cheilitis, which may appear due to a fungal infection or may be part of a set of symptoms for Plummer-Vinson syndrome. At FastlyHealwe provide you with the Definition of cheilosis and its causes.


A disorder of the lips and mouth is characterized by the formation of scales and fissures caused by a diet deficient in riboflavin and perleche or stomatitis. It is an inflammatory lesion in the corner or a corner of the mouth and is often bilateral.

On the other hand, it is known as angular cheilitis to the lesions produced in the labial commissure that can be unilateral or bilateral. In some cases where the injuries are more severe, the fissures can bleed when the mouth is opened, as well as form ulcers or scabs.

The treatment for angular chelitis varies depending on the cause, and it is advisable to go to the dentist or the family doctor.

For mild cases caused by a bacterial infection, applying a topical antiseptic cream to the area for several days is enough to treat the disease and heal the lesions. Minor cases caused by a fungal infection can be treated with antifungal creams. The most severe issues of cheilosis may require the intervention of a dentist.

Causes of cheilosis

Riboflavin deficiency

A diet with low riboflavin levels can lead to flaking of the skin and the presence of cracks. Riboflavin is necessary for the metabolism of carbohydrates, fats, and proteins and to obtain energy for the body. In addition, it also has antioxidant powers. A riboflavin deficiency occurs when a person has other nutritional deficiencies, such as a lack of B vitamins, leading to choice and other symptoms such as a sore throat or swollen tongue. The recommended daily amount of riboflavin or vitamin B2 is 1.3 mg in adult men and 1.1 mg in pregnant women. Among the foods rich in vitamin B2 are meat, fish, eggs, cheese, and some grains and vegetables.


Minor cheilosis is produced by fungi or bacteria. In these cases, the treatments are usually the application of creams that combat the agents for several days.
