Actinic keratoses (AK) are areas of sun‐damaged skin found mainly on parts of the body which have received lots of sun exposure. At first, they can be hard to see, and are more easily felt, being rough, like sandpaper. They may grow to a centimetre or two in diameter. Up to 20% of AKs may progress to a type of skin cancer called squamous cell carcinoma (SCC) within 10 to 25 years.
