Cell Glow recommends: Red and NIR light can influence inflammatory processes, but 'inflammation' is not a diagnosis that one panel can treat. Choose RLT for a defined goal supported by relevant research; have a red, hot, painful or rapidly worsening area assessed first.
What is the mechanism?
Photobiomodulation is examined for cellular signals, blood flow and inflammatory markers. Much of this comes from laboratory and animal research. Clinical evidence must then demonstrate that a clearly defined condition improves in humans compared to placebo or standard care. Without that distinction, a biological effect too quickly becomes a medical promise.
Why does it differ per complaint?
A skin reaction, an inflamed tendon and an infection require different diagnostics. Light source, wavelength, dose and application site also differ. Evidence for pain reduction in knee osteoarthritis has been described, but with very low certainty. For lower back pain, a review found no clinically important benefit over sham treatment.
When to seek help?
A warm, red, rapidly increasing or feverish spot could be an infection. Do not use light as a substitute for medical care. Anyone who wants to try light as a supplement should discuss the purpose and a measurable result with their practitioner.
