Editorial standards

Our aim is to make red light therapy information understandable and useful. Each article should help you see what the evidence supports, what remains uncertain and how the findings relate to the question you are asking.

Sources that readers can inspect

We prioritize original human studies, systematic reviews and guidance from recognized medical organizations and regulators. Sources are linked so you can inspect the research or official guidance behind a claim.

Laboratory research can help explain how light interacts with tissue. We identify it as laboratory research and avoid presenting a cellular or animal result as a demonstrated benefit in people.

How we describe evidence

We keep findings attached to the population, device, treatment schedule and outcome studied. We distinguish a completed study from a study protocol, a measured change from a participant's impression, and a biological theory from a clinical result.

Study size, comparison groups, follow-up, commercial funding and other relevant limitations belong alongside the result. We avoid turning one promising study into a universal claim about every device or person.

Authorship and review

The byline identifies who prepared an article. RLC Editorial is the publication's editorial byline. A medical-review credit is used only when a named qualified professional has reviewed that specific content. A review credit on one article does not extend to the rest of the website.

Product information

Where a comparison includes ratings, the page explains what they represent. Publisher preference ratings express our recommendation choices and are distinct from clinical measurements, independent testing and manufacturer specifications. A separate overall preference score need not be the arithmetic mean of category ratings.

We identify where product information comes from: manufacturer specifications, published clinical research or direct testing. Any testing described should explain the model, method and conditions used. Readers should be able to tell what was measured and what was supplied by a manufacturer.

Regulatory claims should identify the relevant jurisdiction, model and intended use. Registration, clearance and approval carry different meanings.

Commercial connection

Red Light Clinician and Luscent Red share an owner. Product recommendations may include Luscent Red.

Updates and corrections

Publication and update dates should reflect actual publication or substantive revision. If you identify a factual error, broken source link or missing context, please send the article URL and the relevant detail through our contact page.

General medical information

Our articles are educational and cannot diagnose an individual condition or determine a personal treatment plan. We encourage readers to discuss persistent symptoms, treatment choices and device suitability with a qualified health professional.
