Chapped Lips

Chapped lips are mainly caused by a lack of sebaceous gland protection, rapid moisture loss, dry and cold weather, frequently licking your lips with your tongue, mouth breathing, or deficiencies in B vitamins and iron. It's recommended to soften dead skin with a warm water compress, then apply a thick layer of pure petroleum jelly to lock in moisture. Avoid tearing or licking them off forcefully. Common Causes • Environment & Habits: Prolonged exposure to air conditioning, cold winds, excessive sun exposure, or habitually licking/biting lips and breathing through the mouth. • Physiological & Nutritional Factors: Insufficient body hydration, deficiencies in B vitamins (like B2, B6, B12) and iron, or taking certain medications (e.g., oral isotretinoin). • Pathological Factors: Causing cheilitis, angular cheilitis, or allergic contact dermatitis. First Aid & Daily Care Strategies • Proper Moisturization: Choose a lip balm without fragrances or minty irritants, or apply a thick layer of pure petroleum jelly to create a protective barrier. • Warm Water Compress: If you have dead skin, gently soften it with a warm water compress or a warm towel. Do not forcibly tear it off with your hands, as this can cause bleeding. • Break Bad Habits: Avoid licking your lips with saliva, as evaporation will take away more moisture from your lips. • Dietary Supplementation: Increase intake of foods rich in B vitamins and iron (e.g., dark leafy greens, egg yolks, whole grains, lean meats). • When to Seek Medical Help: If chapped lips, redness, or blisters persist for more than two weeks without improvement, consult a dermatologist.
