Skincare article: methods and saved evidence

Return to the article

The focused article and existing short skincare summary are completed outputs. A more extensive skincare flagship report remains unfinished.

This article draws on the corrected October 19 reading edition of Gist’s skincare foundation. Its mixed-date capture and replacement-run limits remain part of the article. It is not cleared for publication.

AI Overview article

S07 — Population and exclusions

Foundation C01/C13, T01/T10, methods sections 2–3. The selected corpus contains 681 nonempty AIO answers across 30 questions. Eighteen failed original runs were replaced by later runs of the same questions; 292 usable original partial answers were excluded. Replacement runs were not pooled with those original partial answers. The selected captures remain incomplete in disclosed ways.

No inference is made from separately reported defects in later automotive or real-estate collections. This article uses the skincare study’s own evidence and known limitations.

S08 — Product fields recover names

Foundation C11, T04/T07. SKINCARE-03-2 AIO epochs 12, 16, 17 and 18 repeat an introduction-only stored-text version with five structured product titles. Exact titles include “CeraVe Moisturizing Cream” and “The Ordinary Natural Moisturizing Factors + Phytoceramides.”

Across that question’s 20 selected answers, stored prose yields CeraVe 15/20 and The Ordinary 0/20; adding overview snippets/shopping titles yields 19/20 and 4/20. The complete capture audit finds added tracked names in 51/681 answers across 11 questions. These are name-recovery findings, not 51 corrected recommendation labels or proof of complete interface capture.

S09 — Sunscreen recurrence and distinct versions

Foundation C12, T07/T09. The 16 successful SKINCARE-04-2 AIO records contain nine distinct combined stored-plus-structured text versions. One repeats eight times. Vacation and Colorescience each appear in 9/16 records and 2/9 versions; Black Girl Sunscreen appears in 5/16 and 5/9. Supergoop and La Roche-Posay occur in 16/16 and 9/9.

The run contains 32 failed saved epochs, excluded from these denominators. Distinct text is a sensitivity unit, not a claim of independent retrieval or a uniquely correct recommendation rate.

S10 — Source-family sensitivity

Foundation C04/C12, T05/T09; source-task-engine-outcomes and source-classification-coverage tables. In AIO, the equal-question average incidence of mapped social/video/forum hosts is 83.8%; grouping identical stored prose and unioning each group’s source families yields 82.1%. Listed skincare-brand domains change from 37.8% to 32.7%.

The source map leaves 1,804/5,727 AIO answer–host pairs unclassified, or 31.5%. Families overlap within answers. They are not shares of a single citation pool or estimates of source quality. This source check groups stored prose; S09 groups combined stored-plus-structured content. The two procedures answer different sensitivity questions.

S11 — Concrete platform/source example

SKINCARE-03-2|aioverview|12 preserves citation URLs on YouTube, Instagram, Facebook, beauty-publisher sites and theordinary.com. Selected saved evidence is available below. The article claims coexistence only: no source-body, causality, creator identity or influence assessment.

Selected saved excerpts and capture fields are available below. Independent review was scoped to selected claims and evidence; it was not complete independent semantic recoding.
