What should I do if angular cheilitis keeps recurring?

Angular cheilitis that fails to heal may be related to incomplete removal of the underlying cause, bad habits, nutritional deficiencies, reduced immunity, and other factors. To address this issue, the following measures can be taken: 1. Identify the cause: Recurrent angular cheilitis may be associated with bacterial infection, fungal infection, viral infection, malnutrition, or trauma. Targeted treatment should be administered after the specific cause is identified. 2. Medication: Based on the underlying cause, use appropriate antibiotics, antifungal agents, or antiviral medications under a doctor's guidance, such as erythromycin ointment, miconazole ointment, or acyclovir ointment, applied topically to the affected area. 3. Correct bad habits: Avoid bad habits such as lip licking or biting, maintain cleanliness and moisture in the corners of the mouth, and avoid using cosmetics or skincare products with strong irritants. 4. Nutritional supplementation: Eat more foods rich in vitamins and minerals, such as vegetables, fruits, and animal livers. Vitamin supplements may also be taken when necessary. If symptoms persist or fail to improve, prompt medical consultation is recommended.
