HOW RED LIGHT THERAPY WORKS
Red (≈630–660 nm) and near‑infrared (≈800–850 nm) light penetrate skin and soft tissue and are absorbed by mitochondrial chromophores—especially cytochrome c oxidase—boosting ATP production. That rise in cellular energy supports faster tissue repair, increased collagen synthesis, reduced inflammatory signaling, and improved cellular resilience, helping wounds close sooner and skin recover more effectively.
These wavelengths also improve microcirculation and trigger nitric‑oxide–mediated vasodilation, enhancing delivery of oxygen and nutrients and clearing metabolic waste. Clinically and practically, this means faster healing, less swelling and bruising, reduced pain after injury or exercise, and better endurance and recovery. NIR penetrates deepest to reach muscles, joints, and other deep tissues for pain relief and recovery, while red light is especially effective at skin‑level outcomes like collagen stimulation, texture improvement, and surface wound repair.
