Abstract

Actinic keratoses are common, often multiple, epidermal lesions found mainly on the sun-exposed skin of fair-skinned middle-aged and older people.¹ Over time, lesions may remain unchanged or may proliferate, regress, reappear or develop into squamous cell carcinoma (SCC).² Detectable (spot) lesions are often associated with alteration of the surrounding skin (field) where subclinical lesions might be present.² Interventions may target individual or multiple lesions or a whole field.² Here, we update our previous review³ on the prevention and treatment of actinic keratoses, focusing on the licensed treatments most commonly used in the UK and recommended in UK guidelines.
