Introduction
Angular cheilitis, also known as cheilosis or perleche, is a common inflammatory condition that affects the corners of the mouth, causing painful cracks, redness, and irritation. It can affect individuals of all ages but is more prevalent among the elderly, denture users, and those with weakened immune systems. The condition, often confused with cold sores or eczema, is distinct in its causes and treatment requirements. In Korea, where skincare and oral health are integral to cultural practices, angular cheilitis treatments are often innovative and highly effective.
Though angular cheilitis may appear as a minor inconvenience, it can significantly impact a person’s quality of life, particularly when eating, speaking, or smiling. The condition is also a potential indicator of underlying health concerns such as nutritional deficiencies or fungal infections. Korea, renowned for its advancements in dermatology and skincare, offers a variety of effective treatments and preventive measures, making it a hub for addressing such conditions both locally and internationally.
Causes of Angular Cheilitis
Primary Causes
Angular cheilitis commonly arises due to infections caused by fungi or bacteria. Candida-induced cheilitis, a fungal infection, is one of the leading culprits, thriving in the moist environment of saliva trapped in the mouth corners. Bacterial infections, such as those caused by Staphylococcus aureus, can also lead to this condition. Other factors, such as frequent lip licking, can exacerbate the irritation, creating a cycle of chronic inflammation.
Secondary Causes
Secondary causes often involve systemic health issues. Nutritional deficiencies, particularly a lack of Vitamin B2 (riboflavin) and iron, can make individuals more susceptible. Medical conditions such as diabetes or immune disorders may also increase the risk of angular cheilitis by impairing the body’s ability to fight infections. Poorly fitting dentures or braces, which can alter the alignment of the mouth, are additional contributors, particularly among elderly individuals.
