Actinic keratosis (AK) is a common skin disorder that can progress to invasive squamous‐cell carcinoma. AK can present as clinical (visible) or subclinical (invisible) lesions within areas of chronic sun damage. The importance of treating subclinical AK is gaining support. We present a subanalysis of a previously published Phase III, double‐blind, vehicle‐controlled study (NCT02289768), to assess 5‐fluorouracil (5‐FU) 0.5%/salicylic acid 10% treatment of subclinical AK lesions, based on reflectance confocal microscopy (RCM).
