What do chapped lips mean?

Why do lips get dry so easily?

Lip skin is thin and has no oil glands, leaving it vulnerable to drying out. Chapping can feel tight, look flaky or cracked, and cause itching or mild pain. Cheilitis is the medical word for inflamed lips. Winter is a common trigger, but hot, dry weather can cause trouble too, so chapping does not respect the seasonal skincare calendar.12

Do chapped lips mean dehydration?

Sometimes, but not necessarily. Dehydration leaves less water available to the skin and can make lips dry and flaky. Drinking plenty of water helps maintain hydration, but weather, saliva and irritating lip products can cause chapping too. Water addresses dehydration; lip balm helps keep moisture from escaping. Neither replaces the other when both problems are present.13

How to help chapped lips heal

1. 1Choose a fragrance free lip balm or ointment. For very dry, cracked lips, try white petroleum jelly, which seals in water longer than waxes or oils. While lips heal, avoid menthol, camphor, eucalyptus, fragrance, flavoring, lanolin and salicylic acid.
2. 2Wash your hands before applying balm. Apply it when you wake up, whenever lips feel dry and before bed. Reapply after eating and drinking. Keep your own balm rather than sharing it, because sharing can spread germs.
3. 3Before going outdoors, apply lip balm with SPF 30 or higher containing zinc oxide or titanium oxide. Reapply every two hours outdoors. Cover your lips with a scarf in cold weather.

Avoid licking, biting or pulling off flakes. Saliva makes lips dry out faster, and picking can create cracks and sores. Apply balm instead when you catch yourself licking. A humidifier can reduce moisture loss in dry indoor air, especially in a bedroom if you breathe through your mouth at night. Balm keeps existing moisture in, which is a less glamorous job than the flavor selection suggests.34

Stop using any lip product that burns, stings or tingles. Those sensations indicate irritation, not that a treatment is working. A pharmacist can help you choose another product or decide whether you need a doctor.45

What if only the corners crack, or peeling never stops?

Painful cracks at the mouth corners, especially when opening your mouth, can be angular cheilitis. Prolonged contact with saliva is its most common cause; infection can also be involved. Frequent use of a thick ointment is often enough for saliva related cases, but treatment for infection depends on the cause. A clinician can assess persistent cracking, crusting or oozing.7

Continuous, recurring peeling can occur in a rare condition called exfoliative cheilitis. Licking, biting, picking and mouth breathing can worsen it. Other conditions can look similar, so persistent peeling needs assessment rather than a diagnosis based on appearance alone.2

When should you see a doctor?

Expect noticeable improvement within two to three weeks of consistent care. See a doctor sooner if lips become hot, painful and swollen, which can indicate infection, or if symptoms worsen. Frequent bleeding or no improvement after a few weeks also needs assessment. Persistent chapping can involve an allergy, nutritional deficiency or medication reaction, including retinoids. Persistent dry, scaly lips can also be actinic cheilitis, a precancerous condition linked to sun exposure.3456
