What Type of Light Is Red Light Therapy? A Science-Backed Guide to Wavelengths & Benefits
Red light therapy (RLT), also known as photobiomodulation, uses specific wavelengths of visible red and near-infrared (NIR) light to support cellular function and tissue repair. Unlike UV light, which can damage skin cells, red light therapy works at non-ionizing wavelengths that are widely studied for their biological effects. 1. The Core Light Types Used in […]
