Daylight photodynamic therapy for actinic keratoses: a randomized double‐blinded nonsponsored prospective study comparing 5‐aminolaevulinic acid nanoemulsion ( <scp>BF</scp> ‐200) with methyl‐5‐aminolaevulinate

Abstract

BF-200 ALA showed a trend towards improved efficacy results compared with MAL. Thicker lesions in both groups responded when treated repeatedly. Importantly, a thin 0·25-mm layer of the photosensitizer precursors was sufficient, which may lead to lower expense.
