Actinic Keratosis

Actinic keratosis (AK) is a rough, scaly patch on the skin caused by prolonged ultraviolet exposure. Fair-skinned people living in high-UV environments, including expats across Southeast Asia, Australia, and South Asia, are particularly susceptible. Left untreated, a small proportion of AK lesions can progress to squamous cell carcinoma, so early attention matters.

Topical treatments for actinic keratosis

For isolated or multiple lesions, topical creams are a common first approach. Imiquimod works by stimulating the local immune response to clear abnormal cells, while fluorouracil is a cytotoxic agent that selectively targets and destroys rapidly dividing damaged skin cells. Both are used under the broader umbrella of skin care and, given AK’s malignant potential, sometimes discussed alongside oncology support resources.

If a lesion changes shape, bleeds, ulcerates, or grows rapidly, see a doctor promptly, these signs warrant clinical assessment beyond topical management.
