Topical treatment for actinic keratosis

Actinic keratoses are rough, scaly or gritty patches caused by accumulated ultraviolet exposure. They may be pink, red, brown, or close to the surrounding skin and can occur on the face, scalp, ears, forearms, or backs of the hands. A clinician should confirm the diagnosis because some lesions resemble other conditions.

Topical options such as 5-fluorouracil or imiquimod treat a field of affected skin rather than only one visible spot. Redness, scaling, crusting, and tenderness can occur during treatment. Sun-Damaged Skin can continue to produce new lesions, so daily protection remains useful.

Apply the prescribed product exactly where directed and keep it away from the eyes, nostrils, lips, and broken skin unless specifically instructed. Do not pick crusts or add exfoliants while the area is inflamed. Use gentle cleansing, a bland moisturiser if advised, and broad sun protection with clothing and shade.

A review checks whether the treated patches have settled and whether any lesion needs a different approach. Cryotherapy (Lesion Removal) or Photodynamic Therapy may be considered for selected lesions. Skin Cancer Screening can help assess other changing areas.

Arrange prompt assessment for a lesion that becomes thick, tender, rapidly enlarges, repeatedly bleeds, develops a persistent sore, or forms a firm raised area. These features do not prove cancer, but they need examination because actinic keratosis can sometimes progress to Squamous Cell Carcinoma. Seek urgent help for facial swelling, breathing trouble, or severe eye irritation after treatment.

Ask which lesions are suitable for topical treatment, how to apply it, what reaction is expected, and when the skin should be checked. Ask how to distinguish a normal treatment response from a lesion needing biopsy or another procedure, and how often your clinician wants future reviews.
