Red Light Therapy (RLT), also known as photobiomodulation (PBM), is a non-invasive treatment that uses low-wavelength red and near-infrared (NIR) light to stimulate cellular function. It harnesses specific wavelengths (typically 630–700 nm for red light, 700–1200 nm for NIR) to penetrate skin and tissues, promoting healing, reducing inflammation, and enhancing energy production.Key MechanismsCellu...
