What Are Chapped Lips? Dry, Cracked Lips Explained
Updated: 3 days ago
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
Quick Answer
Chapped lips, medically called cheilitis, are dry, cracked, peeling lips caused when the thin lip skin loses moisture, often from cold weather, sunburn, lip licking or dehydration. [5] Fragrance-free balms, SPF 30+ lip protection and hydration help, and most cases heal in two to three weeks. [4] [5] See a provider if chapping persists, as it may signal another issue. [5]
Key takeaways
Lips have thinner, more sensitive skin and no oil glands, so they dry out faster than the rest of your body. [5]
Cold, dry weather, sun exposure, lip licking, and dehydration are the most common triggers. [5]
Nine recognized forms of cheilitis exist, from actinic (sun-related) to angular (fungal) and contact (allergic) types. [5]
Treat at home with fragrance-free balm or ointment, SPF lip protection outdoors, a humidifier, and plenty of fluids. [4] [5]
Severely chapped lips take an average of two to three weeks to heal. [5]
See a provider if chapping lasts more than a few weeks or keeps returning, because it may signal an underlying condition. [5]
What the research says
Lip dryness that doesn't go away can be more than weather. A review of actinic cheilitis, a sun-related form of lip inflammation that causes dryness, scaling, and erosions, describes it as a precursor of lip cancer, with a reported rate of malignant transformation of 10 to 30%. The authors stress that early diagnosis and treatment are essential. Risk factors include chronic UV exposure, increasing age, male sex, fair skin, and tobacco use (Vasilovici et al., Front Med, 2022). [1]
Some medicines dry out the lips. A Cochrane review of 31 randomized trials (3,836 people with acne) found that oral isotretinoin, a retinoid, caused more minor adverse effects than oral antibiotics plus topical treatment (risk ratio 1.67, 95% CI 1.42 to 1.98; 351 participants in 2 studies), including dry lips and skin and cheilitis. The evidence was low quality (Costa et al., Cochrane Database Syst Rev, 2018). [2]
What Are Chapped Lips?
Chapped lips are dry, cracked skin on the lips. They usually develop when the lips are exposed to cold or dry weather, sun, frequent licking, or dehydration. The skin on your lips is thinner and more sensitive than the skin on the rest of your body, and lips contain no oil glands at all. [5] Without those natural oil glands, the lips are far more likely to dry out and chap.
Inflammation of the lips is known medically as cheilitis (kuh-LIE-tis). Cheilitis has many possible causes, and lips face more exposure to the elements than the rest of your body. Chapped lips can happen at any time of year, although wintertime is often the hardest on them because cold, dry air strips away moisture. Most people experience chapped lips at some point, and they are typically harmless and temporary. For some people, however, cheilitis reflects a more serious underlying medical problem. [5]
Symptoms of Chapped Lips
Chapped lips usually produce obvious signs because the affected area is so visible. The most common symptoms include:
Symptom | What It Looks or Feels Like |
Dry or scaling lips | Lips feel tight and rough with flaky, scaly patches |
Cracking skin | Fissures or splits form on the lip surface |
Peeling skin | The outer layer of lip skin flakes away |
Itching | A persistent tickle or urge to rub the lips |
Mild pain | Discomfort, especially when the lips stretch or smile |
Sores on lips and in the mouth | Tender spots inside or around the mouth |
Do chapped lips hurt?
They can. Severely chapped lips feel dry and tight and can be very uncomfortable. When cracks deepen, eating can cause painful stinging, especially with citrus, spicy, or salty foods that touch the raw, split skin. [5]
Causes of Chapped Lips
Several everyday factors can trigger chapped lips. The most common causes include:
Cause | How It Dries Out the Lips |
Sunburn | Ultraviolet exposure burns the thin lip skin |
Cold weather | Cold air pulls moisture from the skin |
Hot or dry weather | Heat and low humidity dehydrate the lips |
Frequently licking lips | Saliva evaporates quickly and strips moisture |
Medical conditions | Allergies, thyroid disorders, and some autoimmune disorders can cause lip dryness |
Medication reaction | Drugs such as retinoids can dry or inflame the lips |
Vitamin deficiency | Low iron or vitamin B levels contribute to lip problems |
Dehydration | Not drinking enough fluid dries the whole body, including the lips |
Types of Cheilitis
When lip inflammation becomes more than everyday dryness, it falls into one of nine recognized types of cheilitis. [5]
Type | What Causes It |
Actinic cheilitis | Frequent sun exposure |
Angular cheilitis | Fungal infection at the corners of the mouth |
Contact cheilitis | An allergic reaction to lip products or other substances |
Drug-induced cheilitis | A reaction to a medication, such as retinoids |
Eczematous cheilitis | A flare-up driven by eczema |
Exfoliative cheilitis | Continuous peeling from repetitive behaviors like lip licking |
Infective cheilitis | A viral or bacterial infection, such as herpes simplex |
Glandular cheilitis | Thickening of the salivary glands |
Granulomatous cheilitis | Persistent, painless swelling of the lips |
If your chapped lips keep returning or do not respond to home care, one of these specific types may be responsible, and a provider can help identify which one.
Reviews of cheilitis also group it by how long it lasts. Forms such as simple, angular, contact or eczematous, exfoliative, and drug-related cheilitis are mainly reversible, while actinic, granulomatous, glandular, and plasma cell cheilitis are mainly irreversible. Cheilitis can also appear as part of body-wide conditions such as vitamin B12 or iron deficiency anemia (Lugović-Mihić et al., Acta Clin Croat, 2018). [3]
Who Gets Chapped Lips and What Raises the Risk?
Anyone can develop chapped lips at any age. Certain groups and situations raise the likelihood:
Children and adolescents who lick their lips often can develop lip licker's dermatitis, a rash around the mouth combined with chapped lips. [5]
People in dry or hot climates experience chapped lips frequently. [5]
People in cold climates face seasonal chapping, especially in winter. [5]
People with naturally dry skin chap more easily. [5]
How Are Chapped Lips Diagnosed?
Diagnosis is usually straightforward. A provider performs a visual examination of the lips and the skin surrounding the mouth. [5] If a more serious cause is suspected, additional testing may include:
Test | What It Checks |
Allergy skin test | Whether an allergen is triggering contact cheilitis |
Skin biopsy | A small tissue sample to rule out other conditions |
Blood test | Vitamin levels or signs of an underlying medical issue |
Treatment: How to Heal Chapped Lips
Most chapped lips heal with simple self-care. Follow these steps:
Self-Care Step | Why It Helps |
Stay hydrated | Drinking fluid supports moisture from the inside |
Use lip balm or ointment throughout the day | Seals in moisture and eases discomfort |
Apply lip balm with sunscreen outdoors | Protects the thin lip skin from sunburn |
Avoid licking, picking, or biting lips | Stops the cycle of saliva-driven dryness and further damage |
Keep foreign objects away from your mouth | Pens, jewelry, and metal objects can irritate the lips |
Use a humidifier | Adds moisture to dry indoor air |
Best lip balm ingredients
Not all lip balms help. Look for products that are fragrance-free and hypoallergenic, with ingredients such as:
Ingredient Group | Examples |
Ointments | Petroleum jelly, glycerin |
Oils | Mineral oil, castor seed oil |
Moisturizing agents | Ceramide, dimethicone |
Sun-protective agents | Titanium dioxide, zinc oxide |
Lip balm ingredients to avoid
Some popular ingredients can irritate the lips and make chapping worse. Avoid balms containing:
Irritating Ingredient | Why to Avoid It |
Fragrances and flavoring | Can irritate chapped lips |
Lanolin | Can irritate chapped lips |
Menthol | Can irritate chapped lips |
Eucalyptus | Can irritate chapped lips |
Camphor | Can irritate chapped lips |
Waxes | Can irritate chapped lips |
If your balm causes stinging, burning, or tingling, stop using that product. That sensation means the product is irritating your lips, not working harder. [4] [5] A plain, fragrance-free ointment such as petroleum jelly is a simple alternative. [4]
How often should you apply lip balm?
Apply lip balm or ointment as needed throughout the day whenever the lips feel dry. Lip balm seals cracks, while ointments keep lips hydrated longer, so using a lip ointment at night supports overnight hydration. [5] Always reapply after eating and drinking. [5] When outdoors, choose a lip balm with SPF 30 or higher and reapply about every two hours [4] [5].
What about bleeding lips?
Bleeding happens when cracks (fissures) deepen into cuts or sores, sometimes called a split lip. Treat it at home with a lip-specific ointment. If frequent bleeding does not improve with home treatment, see a healthcare provider for more advanced treatment options. [5]
How long does recovery take?
Regular lip balm eases discomfort while the lips heal. Severely chapped lips take longer, with an average recovery of two to three weeks [5]. Treating chapping early helps lips heal faster and avoids complications such as infection. [5]
Outlook for Chapped Lips
Chapped lips are harmless and cause only temporary irritation until treated. Persistent or severe chapping, however, could signal an underlying medical condition. If your lips are worsening or not healing, see a provider. They may perform allergy, biopsy, or blood tests to find the root cause. [5]
How to Prevent Chapped Lips
Prevention comes down to consistent moisture and protection:
Prevention Habit | How It Protects |
Wear lip balm with SPF before going outside | Blocks sun damage to the thin lip skin |
Apply lip balm or ointment before bed and when waking up | Maintains overnight and morning hydration |
Keep lip balm handy in your bag, on your nightstand, and in your car | Makes reapplication easy throughout the day |
Run a humidifier at home | Counters dry indoor air |
When to See a Healthcare Provider
Treat chapped lips at home first. If there is no improvement after more than a few weeks, see a provider for advanced treatment options and to rule out underlying conditions. [5]
Questions to Ask Your Healthcare Provider
What's causing my chapped lips?
Am I using the appropriate lip balm?
Could my chapped lips be a sign of another medical condition?
What else could this be?
Conclusion
Chapped lips are a common, temporary irritation that most people can resolve at home with the right lip care routine. The lips' unique anatomy, thin skin and no oil glands, makes them especially vulnerable to weather, sun, and habits like lip licking. Staying hydrated, choosing the right fragrance-free balm or ointment, protecting lips with SPF outdoors, and running a humidifier are usually enough to restore comfort within two to three weeks. If your lips stay chapped beyond a few weeks or keep bleeding, a provider can identify whether an allergy, vitamin deficiency, or medical condition is driving the problem.
