Where the data comes from

Skinceptor is a navigation layer over public scientific resources. The current dataset is curated and static: 54 ingredients, 6 biology maps and 96 studies. It is a demonstration corpus, not an exhaustive index of cosmetic science.

Chemical identity: molecular formula, molecular weight, CID, SMILES and 2D structure images.

Protein and enzyme records for biological targets, including accession numbers and functional annotation.

Gene symbols, official names and identifiers for the genes referenced in networks and topic maps.

Curated human pathway definitions used for the pathway tier of every network.

Gene Ontology

Standardised biological process terms where a Reactome pathway is not the right level of description.

Chemical entity ontology identifiers for cross-referencing molecules.

PubMed / Europe PMC

Primary literature. Each curated study links to its PMID or DOI; unverified identifiers link to a title search instead.

Provenance check

When each identifier was last verified

Public records change: accessions are merged, deprecated or re-annotated. Every database reference in Skinceptor stores the date it was checked against the live record, and anything older than 365 days is flagged for re-verification rather than presented as current.

Known limitations

  • Coverage is uneven — well-funded ingredients have far more literature than newer actives.
  • Many cosmetic studies are small, short, industry-funded, or in-vitro only; we label these explicitly.
  • Absence of a relationship here means absence from our curated dataset, not absence from science.
  • Database identifiers carry the date they were last verified; anything past the re-check window is flagged, not hidden.
  • Nothing here accounts for formulation, concentration, pH, stability or individual biology.
