What Are Chapped Lips? Symptoms, Causes, Diagnosis, Treatment, and Prevention

Most people have experienced chapped lips at some point in their lives. Medically known as cheilitis, chapped lips are characterized by cracks or fissures in the lips (usually the lower one) and dryness. Environmental stressors such as wind, cold temperatures, and the sun can lead to chapped lips. Products you use, such as lipstick, lip balm, and even toothpaste, can also cause chapped lips. ( 1 ) According to an article in Acta Clinica Croatia , there are several kinds of cheilitis. The most common types are: Cheilitis simplex Contact or eczematous cheilitis Angular cheilitis Actinic cheilitis Drug-induced cheilitis ( 2 )
Signs and Symptoms of Chapped Lips Symptoms In general, the signs and symptoms of chapped lips include: Cracks or fissures Dryness Redness Peeling That said, your symptoms may vary depending upon the exact type of cheilitis you have. Here are the signs and symptoms of each type: (2) Cheilitis Simplex Lip cracking, usually on the lower lip Contact or Eczematous Cheilitis Dryness, scaling, and fissuring Angular Cheilitis Inflammation and redness at the corners of the mouth Actinic Cheilitis Red patches, puffiness, scaly plaques, and small bumps caused by sun exposure. Drug-Induced Che ilitis Lesions (sores)
Causes and Risk Factors of Chapped Lips Causes The skin on your lips is thinner than on the rest of your body, so it’s more susceptible to dryness and chapping. Generally speaking, common causes of chapped lips include dry or cold weather, overexposure to the sun, and licking your lips too frequently. Here are the specific causes of each type of chapped lips: Cheilitis Simplex Frequent lip licking is usually to blame. Licking your lips too much removes the oily surface film that keeps moisture in and makes them more prone to dryness and cracking. On top of that, digestive enzymes in saliva may irritate lips by extracting moisture from them. Contact or Eczematous Cheilitis The culprit of this type of chapped lips is irritating substances, like preservatives and dyes found in products such as lipstick, toothpaste, certain foods, and even pens. Angular Cheilitis This type of chapped lips is common in people who have deep wrinkles at the corners of their mouths and who lick lip corners frequently. It can also be caused by a vitamin deficiency, such as B6 or zinc, or conditions like celiac disease . It’s frequently found in diabetics and people with psychiatric disorders such as bulimia and anorexia nervosa . Actinic Cheilitis Also known as “solar keratosis,” this kind of chapped lips is due to chronic sun exposure. It’s often found in people who work outdoors such as farmers, construction workers, and lifeguards. Drug-Induced Cheilitis Usually it’s caused by retinoids (used to treat acne or psoriasis) or other medications like topical antibiotics or local anesthetics. (2)
How Are Chapped Lips Diagnosed? Diagnosis Cheilitis simplex (run-of-the-mill chapped lips) can usually be healed with at-home remedies like drinking more water and using nonirritating lip balms. But if your chapped lips are severe, you may need to see a doctor who can make an official diagnosis and recommend targeted therapies, says the American Academy of Dermatology. ( 3 ) To diagnose chapped lips, your doctor will ask about your symptoms, take a careful medical history, and do a clinical examination. They may also need to do a patch test or take a swab of your lips to check for infection. In some cases, a biopsy may be necessary so the skin on your lips can be examined under a microscope. (2)
Duration of Chapped Lips Duration The length of time it takes to heal chapped lips depends on how severe your condition is. Less severe cases, such as cheilitis simplex, can be healed in two to three weeks. If your lips don’t feel better after a few weeks, see a board-certified dermatologist who can determine the proper course of treatment. (3)
Treatment and Medication Options for Chapped Lips Treatment Chapped lips typically heal on their own with at-home treatments. If your chapped lips won’t go away — or if your lips become severely cracked or swollen — see your doctor. These may be signs of an underlying medical problem. (3) Here are targeted treatment options for each type of chapped lips: Cheilitis Simplex Lip balm, petroleum jelly, topical corticosteroids, ointments Contact or Eczematous Cheilitis Topical corticosteroids and emollients such as Vaseline and Aquaphor Angular Cheilitis Topical antifungal medication, antiseptics, antibiotics, topical corticosteroids Actinic Cheilitis Emollients and topical corticosteroids Drug-Induced Cheilitis Emollients and discontinued use of the drug (if possible) (2) Chapped lips will persist until the sun damage is treated. Sometimes, a laser or nitrogen freezings can improve damaged skin. Prevention of Chapped Lips There are a number of steps you can take at home to prevent chapped lips: Try not to lick your lips too much. Saliva evaporates quickly and can leave your lips feeling even more chapped. Protect your lips. For maximum moisture and protection, choose a lip-soothing product that contains beeswax or petrolatum (petroleum jelly, such as Vaseline). Choose a nonirritating (fragrance- and flavor-free) lip product with SPF sun protection if you’re outside for long periods during daylight in cold or dry weather. Cover Up. Cover your lips and face with a scarf on cold, windy days. Stay Hydrated. Drinking plenty of fluids, and even using a humidifier can help, especially in the colder, drier months of the year. Avoid Irritants. Don’t use any personal care products, fragrances, or foods that cause irritation. Close Your Mouth. Breathe through your nose instead of your mouth. ( 4 )
Complications of Chapped Lips Complications Actinic cheilitis (the kind that’s induced by the sun) can lead to squamous cell carcinoma (lip cancer). In rare cases (usually glandular cheilitis and cheilitis granulomatosis), chapped lips can cause permanent swelling. (1)
Research and Statistics: Who Gets Chapped Lips? Research and Statistics Unfortunately, there isn’t precise data on how many people suffer from chapped lips. However, there is research on who is most likely to get each kind: Eczematous Cheilitis This form is most prevalent in people with a history of allergies. Angular Cheilitis This kind of chapping, around the corners of the mouth, is often found in older people who wear dentures and in children with immunodeficiency, which decreases their ability to fight off infection. Actinic Cheilitis This is common in people who live in sunny locales and people with fair skin. Glandular Cheilitis This rare inflammatory disorder is usually found in older men. (1)
Related Conditions and Causes of Chapped Lips Related Conditions Some skin conditions and other chronic disorders can also affect the lips, leaving them feeling dry, cracked, or irritated. These conditions include: Eczema Lichen planus Lupus erythematosus Autoimmune bullous diseases Crohn’s disease Sarcoidosis Certain nutritional deficiencies (1,2)
