Eczematous cheilitis treatment: what to know

Eczematous cheilitis can make the lips dry, red, scaly, cracked, sore, or itchy. Irritant exposure may come from saliva, lip licking, wind, toothpaste, fragranced products, or cosmetics. Allergic contact reactions can follow ingredients in lip balms, flavourings, metals, or dental materials. The pattern and history help distinguish eczema from infection, a cold sore, or another lip disorder.

A clinician may ask what touches your lips and whether symptoms began after a new product. Keeping a short product diary can reveal a trigger. Treatment information for barrier repair is available in [Emollient Therapy](/treatments/medical-dermatology/emollient-therapy/).

Apply a bland, fragrance-free ointment or moisturiser frequently, including after eating and brushing your teeth. Do not lick, bite, peel, or scrub the lips. Pause flavoured balms, plumping products, essential oils, and cosmetics until the skin settles; reintroduce items one at a time only if advised. Drink normally and protect lips from wind and sun with a simple product that does not sting. A prescriber may recommend [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) for a limited course, with strength and duration matched to the delicate lip area. Persistent cases may need trigger investigation rather than repeated self-treatment.

Arrange an assessment if cracking persists, the rash repeatedly returns, one area remains scaly, or eating and speaking become difficult. Seek prompt care for rapidly increasing swelling, pus, spreading redness, fever, or painful grouped blisters. Swelling of the tongue or trouble breathing after a product is an emergency.

Could a product or toothpaste be causing contact allergy? Which moisturiser is least likely to irritate me? How should I use a prescribed steroid on my lips? Do I need patch testing? What symptoms would suggest infection or a cold sore?
