CosmeticFountainThe Beauty Evidence Index
How to read a dossier
CosmeticFountain uses a two-axis model so readers do not confuse “tested” with “safe for everyone,” or “insufficient evidence” with “dangerous.”
A — Strong: multiple quality trials and consistent findings. B — Promising: some quality trials with limited replication. C — Preliminary: small, in-vitro, or biologically plausible evidence. D — Insufficient: no quality studies found. X — Unsupported: reviewed evidence does not support the specific claim.
Clear: no known concerns at standard cosmetic concentrations. Monitor: context-dependent concerns such as pregnancy, sensitive skin, UV exposure, or device parameters. Caution: adverse potential may require professional guidance. Regulatory flag: restricted, prohibited, or classification-sensitive in at least one jurisdiction.
Every full dossier follows the same order: Claim, Evidence grade, Evidence narrative, Uncertainty, Safety context, Verdict, Sources and metadata.
Each dossier is designed to show first publication, last review, methodology version, source count, reviewer type, and grade history when available.
Strong, replicated evidence: “Evidence supports this claim at standard cosmetic concentrations.”
Some evidence, not replicated: “Preliminary evidence is directional but not yet replicated at scale.”
In-vitro only: “Lab findings are promising; human trial data is absent.”
No studies found: “No published human trials were identified for this specific claim.”
Evidence contradicts the claim: “Available evidence does not support the stated claim.”
Manufacturer-funded only: “Available evidence is manufacturer-funded; independent replication is absent.”
