What should you know about dry skin on lips?

The lips have a delicate surface that can lose moisture quickly. Wind, sun, dry air, dehydration, habitual licking, saliva, and fragranced or flavoured lip products may cause tightness, flakes, burning, and cracks. Atopic Dermatitis or contact irritation can affect the lips, and Psoriasis may involve the surrounding skin. Asteatotic Eczema is less typical on the lips but is part of the broader dry-skin pattern. Persistent changes should not be labelled from appearance alone.

Use a bland, fragrance-free ointment or balm several times through the day and before sleep. Reapply after eating or drinking, and use lip protection suited to sun exposure outdoors. Avoid licking, biting, peeling flakes, and products that sting, tingle, or contain strong flavouring. Keep irritating toothpaste or cosmetics away from broken skin. Emollient Therapy principles also apply here: a simple occlusive layer helps reduce water loss while the surface repairs.

Arrange a medical review if lips stay cracked, bleed repeatedly, develop a persistent scaly area, or fail to improve after removing suspected irritants and using bland protection. Seek prompt care for rapidly increasing swelling, spreading redness, pus, fever, or trouble breathing. A sore that does not heal or a change confined to one area also deserves examination.

Could a lip product, toothpaste, medicine, eczema, or sun exposure be contributing? Which balm or ointment should I use? Do I need treatment for inflammation or infection? How should I protect the area while it heals?
