Actinic cheilitis
Actinic cheilitis is a common, sun-induced condition that affects the lips—most often the lower lip. It’s considered a precancerous change, so early recognition and treatment are important for both health and cosmetic outcomes.
Actinic cheilitis (AC) is a form of chronic sun damage that appears on the vermilion border (the pink part) of the lip. Years of cumulative ultraviolet (UV) exposure, fair skin, older age, and outdoor activities all increase your risk. AC is closely related to actinic keratoses on the skin and is considered a type of in situ squamous cell carcinoma (SCC) of the lip.
what does actinic cheilitis look like?
Persistent redness, scaling, dryness, or roughness on the lower lip
Blurring of the border between the lip and surrounding skin
May develop fissures, crusting, or white patches
Usually painless, but may feel mildly tender or sensitive
Any ulceration, thickening, or persistent change should be checked by a dermatologist, as these can indicate progression to skin cancer
why is it important to treat actinic cheilitis?
Actinic cheilitis is more than just dry or chapped lips—it is a marker of significant sun damage and carries a risk of progression to invasive SCC (skin cancer of the lip). Ongoing monitoring and early treatment help prevent complications and support the best possible outcome.
how is actinic cheilitis treated?
Treatment is tailored to the severity and extent of the condition, as well as your personal and medical history. Options include:
CO2 Ablative Laser
How it works: The CO₂ laser precisely removes abnormal cells from the lip’s surface, targeting sun-damaged tissue while preserving healthy structures.
Benefits: High clearance rates (80–100%), excellent cosmetic results, and quick healing (typically 1–2 weeks).
What to expect: The procedure is performed in-clinic, followed by a short recovery with antiseptic soaks and moisturisers. Some redness and swelling are normal and resolve as the lip heals.
Risks: Temporary redness, swelling, pigment changes, and rarely, scarring.
Other Treatment Options
Cryotherapy: Freezing small, isolated spots (may cause lightening or scarring of the lip).
Prescription creams: Such as 5-fluorouracil or imiquimod, which can be effective but may cause a strong inflammatory reaction.
Photodynamic Therapy (PDT): A light-based treatment suitable for widespread sun damage. Learn more about Photodynamic Therapy.
Surgical excision: Reserved for suspicious or persistent lesions.
what’s The Next Step?
If you notice persistent roughness, redness, or changes to your lips—especially if you have a history of sun exposure—early assessment and treatment can make a significant difference. Dr Liz Dawes-Higgs is highly experienced in the diagnosis and management of actinic cheilitis, including advanced CO₂ laser treatments for field damage.
