What are the treatment options for actinic cheilitis?

Actinic cheilitis is usually linked to repeated sun exposure and can make the lip feel rough, dry, scaly or less clearly bordered. It often affects the lower lip. Because a persistent area can contain more advanced change, a clinician may examine it closely and take a sample when the appearance is unclear or concerning.

Topical 5-fluorouracil is applied in a prescribed course to treat abnormal sun-damaged cells and can cause redness, soreness or crusting while it works. Photodynamic therapy uses a light-sensitive medicine followed by a specific light treatment. CO2 laser resurfacing removes or treats affected surface tissue with controlled energy. The choice depends on the extent and thickness of the change, examination findings, healing needs and previous treatment. Use lip sun protection, a broad-brimmed hat and a protective balm, and avoid picking crusts.

Book a prompt dermatology assessment for a rough, scaly or persistently cracked lip that does not settle with moisturising and sun protection. Seek earlier review for a sore that bleeds, becomes firm, forms a persistent crust, enlarges or causes increasing pain. Do not cover a changing lesion with cosmetic products without arranging an examination.

Ask whether the area needs a biopsy, which treatment fits its extent, what reaction to expect, how to protect the lip during healing and when the site should be checked again. Mention previous skin cancers, immune problems and medicines.
