Safety
Near Infrared light in clinical use at appropriate irradiances has been described since more than 15 years as helpful and safe. In accordance with previous studies, NIR is unlike ultraviolet especially not implicated in photoaging of the skin, mediated by the collagenase matrix metalloproteinase 1 (MMP-1).
