Results: The treated subjects experienced significantly improved skin complexion and skin feeling, profilometrically assessed skin roughness, and ultrasonographically measured collagen density. The data collected at baseline and after 30 sessions included blinded evaluations of clinical photography, ultrasonographic collagen density measurements, computerized digital profilometry, and an assessment of patient satisfaction. Irradiances and treatment durations varied in all treatment groups. Of these volunteers, 113 subjects randomly assigned into four treatment groups were treated twice a week with either 611вЂ“650 or 570вЂ“850вЂ‰nm polychromatic light (normalized to в€ј9вЂ‰J/cm 2 in the range of 611вЂ“650вЂ‰nm) and were compared with controls ( n=23). Materials and methods: A total of 136 volunteers participated in this prospective, randomized, and controlled study. Because the action spectra for tissue regeneration and repair consist of more than one wavelength, we investigated if it is favorable to apply a polychromatic spectrum covering a broader spectral region for skin rejuvenation and repair. However, lasers and LEDs may offer some disadvantages because of dot-shaped (punctiform) emission characteristics and their narrow spectral bandwidths.

Background data: For non-thermal photorejuvenation, laser and LED light sources have been demonstrated to be safe and effective. Objective: The purpose of this study was to investigate the safety and efficacy of two novel light sources for large area and full body application, providing polychromatic, non-thermal photobiomodulation (PBM) for improving skin feeling and appearance.
