RESULTS

Goal

Subjects received a monochromatic 415 nm blue treatment, or a polychromatic 415 nm and 660 nm treatment. Groups 3 and 4 received cool white light and 5% benzyl peroxide. Patients treated themselves 1x/day for 15 minutes for 12 weeks. At weeks 4 and 8, the red and red-blue groups achieved similar lesion reductions. At week 12, the blue-red group had significantly better results than blue alone. The blue-red group had a 76% inflammatory lesion reduction, significantly higher than the blue light, white light, and benzyl peroxide treatment.

In cataloguing this study, the “cool white light” is classified as having “unknown” wavelengths.
