Angular Cheilitis is also known under the name or cheilosis or angular stomatitis. This condition affects the skin around the lips leading to painful cracks most often in the corners of the mouth. In severe cases, the cracks can become inflamed, can bleed and sometimes infections are developed inside those cracks, which can make normal and banal actions, like talking or eating, a painful nightmare for the sufferer.
In most cases there is a cumulus of factors which lead to this condition. Probably the most important factor is the presence of moisture inside the mouth’s folds. This moisture favors the accumulation of bacteria which will eventually lead to irritation and even infection. Shallow ulcerations are also very often in severe case, these forming a crust if they are not wiped out from the surface. see more at :
