Chapped and Dry Lips
Chapped and Dry Lips — a common condition in which the thin skin of the lips loses moisture and becomes tight, flaky, cracked, or sore. Because lips lack oil glands and have a very thin protective barrier, they are especially prone to dryness from cold air, wind, sun, and frequent licking. Consistent hydration and protection usually restore comfort, while persistent cracking may need closer attention.
Key points
- Lips have no sebaceous glands and a thinner barrier than facial skin, making them quick to lose moisture.
- Cold, dry, or windy weather and repeated lip-licking are frequent contributors to chapping.
- Emollient and occlusive ingredients like petrolatum, shea butter, and beeswax help seal in moisture and protect the barrier.
- Cracks at the corners of the mouth or lips that will not heal may indicate an infection or deficiency and warrant professional advice.
Frequently asked
Why does licking my lips make them drier?
Saliva evaporates quickly and can carry away moisture, while its enzymes may further irritate the delicate lip skin. This often leaves lips drier than before, creating a cycle of licking and chapping.
What ingredients help soothe chapped lips?
Occlusives like petrolatum and beeswax lock in moisture, while emollients such as shea butter and plant oils soften the skin. Applying a lip product with SPF also helps protect against sun-related dryness.
