The aim of this study was to explore the effect of medical LED (830 nm and 590 nm) in the prevention and treatment of PIE and PIH. Methods The in vivo PIE/PIH model was simplified to erythema and pigmentation reaction after acute UVB exposure. 308 nm LED light (225 or 270 mJ/cm²) was induced in vivo in the PIE/PIH model on the thigh of ten healthy subjects. Every subject received therapeutic and preventive irradiation (n = 10 in each group). 830 nm (60 J/cm²) and 590 nm LEDs (20 J/cm²) were irradiated, respectively. For therapeutic irradiation, the PIE/PIH model was induced on D1, and LEDs were irradiated on D0, 1, 3, 6 and 8. For preventive irradiation, LEDs were irradiated on D0, 1, 3, 6, and 8 and the PIE/PIH model was induced on D9. Erythema index (EI), melanin index (MI), transdermal water loss (TEWL), and C-Cube photography were measured during 10-day follow-up visits.
