Index breakdown

  • Study design quality32% × 28%

    Mean design weight across curated studies (meta-analysis 1.0, RCT 0.9, other human 0.7, review 0.45, animal 0.35, in-vitro 0.25).

  • Human evidence share0% × 22%

    Proportion of curated evidence measured in people rather than cells or animals.

  • Evidence volume63% × 14%

    Log-scaled count of curated studies, so volume alone cannot dominate the score.

  • Largest sample size0% × 12%

    Log-scaled largest reported sample size across curated human studies.

  • Replication0% × 12%

    Independent human studies, capped at three; one study is never treated as replicated.

  • Recency25% × 7%

    Linear decay over a twenty-year window from the most recent curated publication.

  • Source traceability0% × 5%

Ingredient fingerprint

7 nodes · 6 relationships · seed "arbutin"

The fingerprint is a deterministic visual signature: ridge amplitude comes from the number of entities in each tier, node placement from identifier hashes, and opacity from confidence. Two ingredients can never produce the same figure unless their networks are identical.

Hydroquinone safety and regulatory status in topical depigmenting use

Summarises efficacy in melasma alongside reported risks including exogenous ochronosis and the resulting regulatory restrictions.

Limitations — Review; regulatory status varies by region and changes over time; identifier not verified during curation.

In-vitroInternational Journal of Cosmetic Science · 2004

Alpha-arbutin inhibits melanin synthesis in human melanocyte culture

Reported dose-dependent reduction of melanin content in cultured melanocytes.

Limitations — In-vitro only; hydroquinone release in skin not quantified; identifier not verified.

In-vitroBioscience, Biotechnology and Biochemistry · 2004

Alpha-arbutin and beta-arbutin: comparative tyrosinase inhibition in vitro

Reported stronger tyrosinase inhibition for the alpha isomer than the beta isomer in enzyme assays.

Limitations — Enzyme assay only, no skin model; identifier not verified during curation.
