How is actinic keratosis different in outdoor workers?

Actinic keratosis is a rough, dry, scaly patch caused by cumulative ultraviolet exposure. It commonly affects the face, ears, scalp, forearms, and backs of hands. Outdoor workers may have several patches, different shades of redness or brown, and areas of sun damage that make a new spot less obvious. A patch can feel rough before it is easy to see. It is considered a precancerous change, so assessment helps guide follow-up.

Use broad-spectrum sunscreen as directed, reapply during outdoor work, and combine it with a brimmed hat, protective clothing, shade, and planned breaks away from direct sun. Check exposed skin regularly, including the ears and scalp. Do not scrape or burn a rough patch at home; a clinician can confirm the diagnosis and discuss suitable treatment.

Arrange a skin assessment for a patch that is growing, thickening, bleeding, tender, crusting, or failing to heal. Seek prompt review if it changes quickly or becomes a firm sore. Urgent care is appropriate for severe swelling, infection signs, or a serious reaction to a product.

Does this rough patch need treatment or monitoring? How should I protect exposed skin during work? Which changes should prompt an earlier appointment?
