Red Light Therapy Basics

Red light therapy is widely considered a safe, non-invasive wellness and skincare treatment, and it’s used daily in medical offices, physical therapy clinics, dermatology practices, and med spas across the country.

Red light therapy (often called RLT, photobiomodulation, or low-level light therapy) is a non-invasive wellness and recovery technology that uses specific wavelengths of red and near-infrared light to support how your body’s cells produce energy. People commonly use red light therapy for skin health, muscle recovery, joint comfort, inflammation support, and overall wellness either in a clinic setting or with at-home devices.
