Health content carries higher responsibility than most. People make real decisions — about money, about their bodies, about whether to delay seeking medical care — based on what they read online. We take that responsibility seriously. This page documents how we research, write, fact-check, and maintain the content on Red Light Benefits.

Sourcing hierarchy

When we make a factual claim, we draw from sources in this order of preference:

  1. Systematic reviews and meta-analyses in peer-reviewed journals (typically indexed on PubMed or Cochrane).
  2. Randomized controlled trials (RCTs) published in peer-reviewed journals, with adequate sample sizes and reasonable blinding.
  3. Mechanistic studies (in vitro, animal models) when human data is sparse — explicitly labeled as such.
  4. Clinical guidelines and position statements from recognized medical bodies (e.g., American Academy of Dermatology).
  5. Manufacturer technical specifications for device claims like wavelength, irradiance, or FDA clearance status — verified against the FDA 510(k) database where applicable.

We do not cite blog posts, marketing pages, social media, or unverified anecdotes as evidence for biological claims.

How we write

Each article follows a consistent process:

  1. Topic scoping. We identify the questions a reader is actually asking — not just keyword variations — and outline an article that answers them directly.
  2. Literature review. Primary sources are gathered from PubMed, Cochrane, ClinicalTrials.gov, and the relevant subspecialty journals. We read studies in full, not abstracts.
  3. Drafting. Content is written in plain language with clear structure: what it is, how it works, what the evidence shows, how to use it safely.
  4. Fact-check pass. Every numeric claim, study citation, and biological mechanism statement is verified against its primary source.
  5. Editorial review. A second editor reviews for clarity, balance, and tone — flagging any claim that overstates or understates the underlying evidence.
  6. Publish and date-stamp. Every article shows a "Published" and "Last Updated" date.

How we handle uncertainty

Red light therapy research is uneven. Some applications (skin rejuvenation, wound healing, hair growth) have strong, repeated RCT evidence. Others (thyroid, depression, fat loss) have promising early results but lack large-scale confirmation. We label this clearly:

  • "Strong evidence" — multiple high-quality RCTs or systematic reviews showing consistent results.
  • "Moderate evidence" — one or more RCTs, but limited replication or moderate effect sizes.
  • "Preliminary" — small studies, mechanistic data, or single-trial findings that haven't been independently replicated.
  • "Insufficient" — claims that lack credible human evidence; we explicitly say when something is not supported.

Conflict of interest policy

Red Light Benefits earns affiliate commissions when readers purchase devices through our links. To prevent this from biasing our content:

  • Product recommendations are made before commission rates are checked, not after.
  • We never accept free devices, paid placement, or sponsored content disguised as editorial.
  • If a top-recommended device pays no commission (or a lower commission than alternatives), it stays as the top recommendation.
  • We disclose every affiliate link inline, not just in the site-wide disclosure.

Updates and corrections

The science of photobiomodulation moves. New studies publish constantly, devices get updated, and prices change. To keep articles accurate:

  • Quarterly review. Every published article is reviewed at least once per quarter for accuracy, with the "Last Updated" date refreshed when meaningful changes are made.
  • Reader-flagged corrections. Any reader can report an error via our contact page. Verified corrections are made promptly and noted in the article.
  • Major revisions. When new evidence substantially changes a recommendation, we say so explicitly in the article rather than silently rewriting.

What we will never do

  • Diagnose conditions or recommend treatment plans for individuals.
  • Tell readers to stop, start, or adjust prescription medication based on what they read here.
  • Promise specific outcomes from any device or protocol.
  • Promote devices or claims that are not supported by credible evidence, regardless of commission potential.
