Research Scope and Qualification

The public benchmark is narrower than the raw collection universe by design. Brand-level percentages use the qualified observations as the public denominator, not the raw collection.

Recommendation Placement Snapshot

Questions This Section Answers

• How do top-three and rank-one placement differ among the three leading luxury skin care brands?
• Can a brand with lower recommendation coverage still match the leader on rank-one rate?

Coverage alone does not show how prominently a brand is recommended. The three leading brands show differing relationships between top-three and rank-one placement. In October 2026, Augustinus Bader held a 35.6% top-three rate and a 14.3% rank-one rate. La Mer held a 31.8% top-three rate and a 13.9% rank-one rate. SkinCeuticals held a 26.6% top-three rate and a 10.5% rank-one rate.

Similar coverage can still hide different first-position rates: La Mer and Augustinus Bader ended October 2026 within 0.4 points of each other on rank-one rate despite a 6.2 point gap in valid recommendation coverage.

Buyer-Intent Distribution

Top 10 Cited Domains

Questions This Section Answers

• Which domains do AI platforms cite most often in luxury skin care recommendations?
• How reliant are AI recommendations on third-party editorial and retailer domains versus a brand's own site?

Across all AI platform responses in October 2026, 6,470 citations resolved to 1,603 unique domains.

Citations are moderately distributed: the top ten domains account for 18.3% of all citations, and no single domain exceeds 7.0%. One tracked brand's own domain appears in the top ten: us.babor.com, the Augustinus Bader site, at rank nine with 88 citations. Beauty editorial and review sites (whowhatwear.com, allure.com, instyle.com) and retail or marketplace domains (bluemercury.com, dermstore.com) together account for a substantial share, suggesting AI recommendations in this vertical draw heavily on third-party editorial coverage and retailer listings rather than on official brand properties alone.

Evidence and Source Layer

Questions This Section Answers

• What evidence does the benchmark retain at the prompt level, and what does source presence not prove?

The benchmark is built from prompt-level observations that retain the query, AI/search surface, answer, brand outcome, recommendation placement, sentiment, and, where exposed, citations or attributable evidence sources. Source presence is evidence about the information environment. It is not automatically proof that the source caused the recommendation.

Scope Boundaries

This public benchmark does not measure market share, attributable sales, every possible AI response, organic-search ranking, social mention volume, private or sponsored channels, or causality from a metric movement alone.
