Hi, Severely chapped lips that are red and peeling can be caused by several factors, including: * Dehydration: When your body is dehydrated, your lips can become dry and cracked. Drinking plenty of water and staying hydrated can help prevent this. * Environmental factors: Exposure to dry or cold weather, wind, or sun can cause your lips to become dry and chapped. * Licking your lips: Saliva contains enzymes that can break down the delicate skin on your lips, leading to dryness, cracking, and peeling. * Allergies or irritants: Certain lip products, toothpaste, or food can cause an allergic reaction or irritation, leading to dryness, redness, and peeling. * Medical conditions: Certain medical conditions, such as eczema or psoriasis, can also cause dry, chapped lips. To help relieve severely chapped lips, you can try the following tips: * Use a gentle lip balm or ointment to keep your lips hydrated and protected. Avoid using products that contain alcohol or fragrance, as they can further dry out your lips. * Drink plenty of water to stay hydrated and prevent dryness. * Avoid licking your lips, as this can further dry them out. * Use a humidifier in your home to add moisture to the air. * Avoid exposure to harsh environmental factors, such as cold or windy weather. If your chapped lips do not improve or if they are accompanied by other symptoms, such as pain, bleeding, or swelling, you should consult a healthcare provider to rule out any underlying medical conditions or infections. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
