What Causes Angular Cheilitis in Infants, and How Is It Treated?
Treatment of infantile angular cheilitis may involve supplementation with vitamins (e.g., vitamin B₂) and folic acid to address underlying systemic deficiencies. Topical management includes moist compresses to remove crusts, application of protective barrier agents (e.g., clear nail polish), and maintaining local cleanliness and hydration. Topical antibiotic ointments may also be applied—but care must be taken to avoid ingestion into the oral cavity. For infectious angular cheilitis, treatment must be tailored to the causative pathogen: topical antiviral, antibacterial, or antifungal agents may be used to suppress microbial proliferation and control infection. In cases of traumatic angular cheilitis, correction of harmful habits—such as habitual rubbing of the mouth corners with fingers or pencils—is essential. Local irrigation and moist compresses, combined with anti-inflammatory medications, may further support healing.

Optimize the infant’s diet by ensuring balanced nutrition and adequate intake of key micronutrients. Encourage healthy eating habits—avoiding picky or selective eating. Provide ample fluids, and include foods rich in vitamins B, C, and E, as well as zinc—such as liver, lean meats, eggs, milk, soy products, carrots, and fresh leafy green vegetables.

Prevent vitamin loss during food preparation: avoid excessive rinsing of rice; refrain from adding alkaline substances (e.g., baking soda) when cooking porridge or beans; wash vegetables thoroughly before cutting; and cook them promptly after chopping. We hope this information proves helpful!
