Summary

The aim of this study is to explore the effect of medical LEDs (830 nm and 590 nm) in the prevention and treatment of PIE and PIH.

Conditions

  • Hyperpigmentation

Interventions

DEVICE

LED

308 nm LED light was utilized to induce an vivo PIE/PIH model on the thigh of subjects. The irradiation dose was 1.5 MED. Five circular experimental lesions measuring 1.5 × 1.5 cm were selected on the thighs, categorizing into five groups: control group, 830 nm LED treatment group, 590 nm LED treatment group, 830 nm LED prevention group and 590 nm LED prevention group. 830 nm LED and 590 nm LED were irradiated, respectively. For therapeutic irradiation, the PIH model was induced on D1, and 830 nm (60 J/cm2, 50 mW/cm2) and 590 nm LED (20 J/cm2, 20 mW/cm2) were irradiated on D0, D1, D3, D6 and D8, respectively. For preventive irradiation, 830 nm and 590 nm LED were irradiated on D0, D1, D3, D6 and D8, respectively, and the PIE/PIH model was induced on D9.
