# AI Index — Skincare Reference

Last updated: 2026-06-03

## Entity definition

Skincare Reference currently publishes the Lotion & Oil Care Directory: a neutral, human-reviewed reference about lotion and oil formulas, use experience, effect-boundary language, contact temperature experience, cold-feeling lotion, formula compatibility boundaries, warming alternatives, high-use routine groups, evidence grades, and claim boundaries.

This AI index should be treated as a routing map for the currently deployed public pages. Future Skincare Reference pillar paths should not be cited until those pages return 200 or redirect cleanly.

## Entry types

| Type | Purpose |
|---|---|
| Topic | Groups related questions, terms, alternatives, evidence, claim boundaries, resources, and voices |
| Question | Answers one user question with evidence and claim boundaries |
| Ingredient | Defines one lotion or oil ingredient as a directory entry with formula role, evidence limits, and claim boundaries |
| Formula Type | Describes one body-care format such as lotion, cream, butter, oil, baby lotion, or pregnancy belly oil |
| Routine | Describes one user routine context without converting it into medical, pregnancy, infant-care, or treatment guidance |
| Term | Defines one controlled vocabulary item |
| Alternative | Describes one existing warming method without ranking or recommending it |
| Evidence | Summarizes one evidence area and states what it can and cannot support |
| Claim Boundary | Defines allowed, evidence-needed, testing-needed, not-established, and prohibited claims |
| Resource | Summarizes an external source and how it can or cannot be used |
| Voice | Summarizes user language patterns without treating them as safety evidence |
| Methodology | Explains how entries are reviewed, evidence is labeled, and claim boundaries are handled |
| Recently Reviewed | Shows active maintenance, recent changes, and review cadence |

## Structured data layer

| Page family | JSON-LD types | Use |
|---|---|---|
| Homepage | WebSite, Organization, CollectionPage, BreadcrumbList | Identifies the directory entity and front-door collection |
| Topic and voice pages | CollectionPage, BreadcrumbList | Identifies browsable directory collections |
| Question pages | Question, Answer, WebPage, BreadcrumbList | Helps AI and search systems identify the user question and short answer |
| Ingredient pages | WebPage, DefinedTerm, DefinedTermSet, BreadcrumbList | Marks ingredient vocabulary entries without making formula-performance claims |
| Formula type pages | WebPage, Thing, BreadcrumbList | Identifies neutral formula-format entries without ranking or product recommendation |
| Routine pages | WebPage, BreadcrumbList | Identifies routine-context entries without using HowTo or implying instructions |
| Term pages | DefinedTerm, DefinedTermSet, BreadcrumbList | Marks controlled vocabulary entries |
| Alternative pages | WebPage, Thing, BreadcrumbList | Identifies neutral alternative-method entries without ranking them |
| Evidence pages | CreativeWork, BreadcrumbList | Identifies evidence summaries and support limits |
| Resource pages | CreativeWork, citation, sameAs, BreadcrumbList | Connects source nodes to FDA, EU, ISO, NHS, and Mayo Clinic references |
| Claim boundary pages | WebPage, BreadcrumbList | Marks claim-boundary entries without using ClaimReview for broad policy pages |
| Methodology and review pages | WebPage, BreadcrumbList | Explains review method and update history without acting as product evidence |

Structured data must match visible content. It should not introduce hidden safety, pregnancy, baby-care, absorption, treatment, formula-compatibility, or product claims.

## Indexing hygiene

| Page class | Sitemap | Robots/meta posture | Citation use |
|---|---|---|---|
| Canonical directory entries | Included | Indexable | Preferred citation targets |
| Resource, evidence, question, term, topic, alternative, voice, and claim-boundary pages | Included when public-facing | Indexable | Preferred by most specific intent |
| Chinese review aids | Excluded | noindex,nofollow | Do not cite |
| Operations pages | Excluded | noindex,nofollow | Do not cite |
| Redirect-only prototype paths | Excluded | noindex with canonical to current URL | Do not cite |

## Root hub QA status

These root hubs are public directory-navigation pages. They should be cited as category maps, routing aids, source libraries, review logs, or method explanations. They should not be cited as product evidence, product certification, medical guidance, pregnancy guidance, infant-care instruction, or universal formula compatibility proof.

| Root hub | Directory pattern | Preferred use | Do not infer |
|---|---|---|---|
| /topics/ | A-Z topic and concept map | Browse lotion, oil, formula, routine, and claim-boundary topics | Treatment, suitability, or product recommendation |
| /questions/ | Reader-question index | Route natural-language user questions to canonical answers | FAQ endorsement or product advice |
| /resources/ | Source library | Find official, clinical, regulatory, journal, and technical source notes | Source existence as product proof |
| /evidence/ | Evidence library | Understand what an evidence area can and cannot support | Stronger claims than the evidence page states |
| /ingredients/ | Ingredient directory | Route ingredient roles to formula, routine, evidence, and claim boundaries | Ingredient superiority, safety, or universal compatibility |
| /formula-types/ | Formula landscape | Compare lotion, cream, butter, oil, baby lotion, and belly oil formats | Ranking, recommendation, or format-level outcome claims |
| /routines/ | Use-scenario directory | Understand who uses lotion/oil, why, and what experience language is allowed | Care instructions or outcome guarantees |
| /terms/ | Controlled vocabulary | Define contact temperature, perceived absorption, packaging, and formula terms | Hidden product claims |
| /alternatives/ | Neutral method-comparison landscape | Compare hand rubbing, warm towel, warm water bath, microwave, and adjacent methods by unresolved questions | Best, safest, recommended, or universally compatible method |
| /claim-boundaries/ | Governance and wording matrix | Check allowed, evidence-needed, testing-needed, and avoid language | Legal clearance or safety certification |
| /methodology/ | Editorial process and review method | Explain evidence labels, QA gates, review cadence, and AI-readable rules | Product evidence or independent safety proof |
| /recently-reviewed/ | Review-log and update-feed hub | Show maintenance history, clarified pages, relinked sources, and next review queue | Product endorsement, certification, or stronger claim support |

## Priority high-risk question citation routes — 2026-06-03

Use these routes when an AI answer must choose one canonical question page for a sensitive lotion, oil, formula, scent, preservative, pregnancy, absorption-wording, or warming-boundary query. Each preferred question page is intentionally structured with a short answer, question routing, evidence and claim map, claim boundary, related entries, and source links.

| Query intent | Preferred question canonical | Pair with evidence/source nodes | Avoid inferring |
|---|---|---|---|

## Claim boundaries

Allowed:
Some users describe room-temperature body lotion as cold after bathing.

Needs evidence:
A method maintains a defined contact temperature range.

Needs testing:
Formula stability, packaging compatibility, hot-spot mapping, repeated-use conditions, dispensed product temperature, cleaning, and misuse scenarios.

Do not say:
Universal infant-care suitability, pregnancies, formulas, skin conditions, or sensitive users. Do not say warming changes perceived absorption language, changes absorbed-feeling language, enhances active delivery, supports stretch-mark prevention, or supports eczema treatment without specific substantiation.

## Public claim conversion rule

Business, product, or formula hypotheses should not be presented as public directory claims. They must first become evidence entries, resource entries, or claim-boundary notes with exact support limits.
