Our standards
Science & Sources
Scientific credibility is part of the brand. Here is how we work with evidence.
What we aim to do
- 01
Reference credible research
Where we make a claim about how something works, we aim to point to peer-reviewed research, clinical guidance, or recognized reference texts. References appear at the end of articles and ingredient entries.
- 02
Distinguish evidence from tradition
Traditional practice is a form of long-term observation and deserves respect — but it is not the same as controlled evidence. We say which is which.
- 03
Acknowledge uncertainty
Much of skincare and nutrition science is smaller, shorter, or more industry-funded than headlines suggest. When evidence is thin, we say so.
- 04
Update as science evolves
Understanding changes. Articles carry publication dates and are revised when meaningful new evidence appears.
- 05
Never present emerging research as settled
An interesting laboratory finding is a reason for curiosity, not a reason to buy something. We keep the two apart.
How we label knowledge
Five kinds of claim, kept distinct.
Education
General explanations of how the body works, drawn from textbooks and reviews. High confidence.
Research findings
Specific studies, with their size, design, and funding noted where relevant. Confidence varies.
Traditional practice
Long-standing use in a culture or tradition. Meaningful, but not a controlled test.
Emerging evidence
Early, small, or laboratory-only findings. Interesting; not yet actionable.
Medical treatment
Prescription therapies and clinical procedures. Outside our scope; we point to professionals.
