Treatment for lichen planus on the lips

Lichen planus is an inflammatory condition that may affect the lips as well as the mouth or skin. Lip involvement can cause dryness, scaling, erosions, tenderness or changes in colour. Itchy Skin and Skin Bumps elsewhere can provide useful clues, but a lip lesion may resemble irritation, allergy, infection or another disorder. A clinician may inspect the lips and mouth and decide whether further testing is needed.

Use a plain, fragrance-free lip balm or ointment and avoid licking, biting, peeling scale, smoking, spicy foods and products that sting. Consider changing toothpaste or cosmetics only with a clear reason, because multiple changes can make triggers harder to identify. Topical Corticosteroids may be prescribed for local inflammation; use the named product for the instructed duration and application site. More extensive disease may lead to discussion of Oral Corticosteroid Treatment or another specialist option.

Arrange a dermatology or oral-medicine review for persistent sores, bleeding, crusting, difficulty eating, or symptoms extending inside the mouth. Seek prompt care for rapidly worsening swelling, inability to drink, pus, fever, or a lesion that becomes firm, changes quickly or fails to heal. Regular review helps distinguish an active flare from infection or another lip condition.

Does the appearance fit Lichen Planus, and is the mouth involved? Which ointment should I use and where should it be applied? Could toothpaste, cosmetics, dental materials or medicines be contributing? Do I need a biopsy, oral review or follow-up examination?
