Experiencing discomfort at the corners of your mouth is a common and bothersome issue. These cracks, often red and sore, can make talking, eating, and even smiling uncomfortable. Understanding their causes is the first step toward relief and prevention. This article explores factors contributing to cracked lip corners, provides home remedies, and outlines preventive measures.
Why the Corners of Your Lips Crack
The medical term for cracked lip corners is angular cheilitis, which involves inflammation and fissuring at the labial commissures. A common cause is saliva accumulation in the mouth’s corner folds, creating a moist environment. This constant moisture can macerate the skin, making it susceptible to infection and irritation.
Nutritional deficiencies, especially a lack of iron or B vitamins like riboflavin (B2) and cobalamin (B12), also contribute. These nutrients are vital for skin health and immune function; their absence weakens the skin barrier.
Fungal infections, often Candida albicans, or bacterial infections like Staphylococcus aureus, frequently colonize these moist areas. Dry weather exacerbates the issue by drying skin, while frequent lip licking introduces irritating saliva and digestive enzymes. Poorly fitting dentures can also create deep folds, trapping moisture and providing an ideal breeding ground for microbes.
Remedies and Relief at Home
When cracked lip corners appear, immediate action can provide relief and promote healing. Keeping the affected area clean and dry is a crucial first step, as reducing moisture inhibits microbial growth. Gently patting the corners of your mouth dry after eating or drinking prevents further maceration. Applying a thin layer of a protective emollient, such as petroleum jelly or a thick lip balm, forms a barrier against irritants and helps the skin retain moisture.
Over-the-counter creams with antifungal or antibacterial agents can address underlying infections. These topical treatments target the specific microorganisms often responsible for angular cheilitis, aiding healing. Avoid irritants like acidic foods, spicy dishes, or harsh oral hygiene products that can further inflame sensitive skin. Consistent application of these remedies significantly reduces symptoms and supports skin repair.
Stopping Cracks Before They Start
Preventing cracked lip corners involves consistent daily habits and addressing underlying factors. Maintaining good lip hygiene, including keeping the mouth area clean and dry, significantly reduces moisture accumulation. Staying adequately hydrated by drinking enough water helps maintain overall skin health, including the delicate skin around the lips.
Addressing nutritional deficiencies, especially iron or B vitamins, through a balanced diet or supplements, strengthens skin resilience. Avoiding excessive lip licking, which introduces saliva and irritants to the mouth corners, is a practical preventive measure. Regularly applying a protective lip balm, particularly in dry or harsh weather, creates a barrier that shields the skin from environmental stressors.
When to Seek Medical Advice
While many cracked lip corners resolve with home care, professional medical attention is sometimes warranted. If symptoms persist or worsen despite consistent home remedies for over a week, consult a doctor. Signs of a severe infection, such as increased redness, swelling, pus, or significant pain, indicate a need for professional evaluation. A healthcare provider can accurately diagnose the cause and prescribe stronger antifungal or antibacterial medications if necessary. Recurrent angular cheilitis or its association with other concerning symptoms may also suggest an underlying health condition requiring medical investigation.
