What is red light therapy? This complete 2026 guide breaks down photobiomodulation in plain English: how red and near infrared light interact with mitochondria, the dose-response science behind wavelength selection, and what peer-reviewed research actually shows for skin, hair, pain and recovery. Covers safety, eye protection, UK regulation, and how to choose between panels, beds and masks for home or clinic use, backed only by PubMed, PMC and Cochrane citations.

Red light therapy accelerates healing and recovery. When combined with hyperbaric oxygen therapy, results improve faster. This comprehensive UK guide covers mechanisms, benefits, protocols, equipment choices, and real case studies from elite athletes and clinics.
