Abstract

A striking consequence of 248-nm excimer laser irradiation of skin is a stable vivid blue fluorescence easily visualized under UVA illumination. Its spectral properties (excitation maximum at approximately 335 nm; emission maximum at approximately 430 nm) are somewhat similar to those of the fluorescent pigments associated with aging of tissue and peroxidation of lipids, and the fluorescent pigments formed during exposure to high temperatures. This study explores the spectral properties, magnitude, dose response, and laser pulse intensity dependence of this phenomenon in both isolated stratum corneum and epidermal cell suspensions from human skin.
