Actinic keratoses (AK) are precancerous epidermal proliferations commonly present on chronically sun-damaged skin. These lesions are among the most often treated dermatologic conditions. We sought to investigate the 6-month safety, tolerance, and efficacy of nonablative 1927-nm fractional resurfacing of facial
