Introduction: What is Red Light Therapy?

Red light therapy (RLT), also known as Photobiomodulation (PBM) and Photodynamic Therapy (PDT), is a non-invasive treatment that uses low-wavelength red light or near-infrared light to stimulate cellular function. It’s gaining traction for its potential to support skin health, reduce inflammation, promote tissue repair, and alleviate neuropathy symptoms.[i]

RLT targets the mitochondria, the energy-producing centers of cells. When exposed to specific wavelengths (typically 600–850 nm), mitochondria absorb the light, stimulate mitochondrial cytochrome c oxidase, and produce more ATP (adenosine triphosphat...
