Ultraviolet‐Induced Fluorescence Dermatoscopy in the Management of Non‐Neoplastic Dermatoses—A Narrative Review

Ultraviolet‐induced fluorescence dermatoscopy (UVFD) is a novel, promising dermatoscopic modality that uses excitation–emission phenomena to visualize endogenous and exogenous fluorophores. By highlighting both visible‐light emission signals and absorption patterns, it provides valuable diagnostic data that complement conventional dermatoscopy. Although its potential for diagnosing and monitoring various dermatoses has been increasingly recognized in recent years, the technique’s role in guiding management decisions has not been comprehensively reviewed. In this narrative review, we integrate current literature with the authors’ clinical experience to demonstrate how UVFD can guide management across inflammatory, infectious, pigmentary, and scalp disorders. Specifically, we focus on how the presence or absence of particular fluorescence patterns—originating from organism‐derived fluorophores, inflammatory metabolites, and treatment‐related changes—may reflect disease activity, predict prognosis, confirm therapeutic response, or serve as a test of cure.
