## SKINBOT

SKINBOT is a neutral AI decision layer for beauty retail. It integrates via API, QR, and iframe, and produces skin-analysis-based product recommendations from the retailer's live catalog. Its defining property is neutrality: no brand weighting, no sponsored ranking, no retention mechanics. Neutrality is treated as architecture, verifiable in the API response itself, not as a marketing claim. Live pilots: THE FACE ONLY (Moscow, 6 locations) and SKINSTUDIO (Estonia, https://skinstudio.ee). Across all pilots, more than 85% of sessions end with delivered recommendations.

## Key concepts coined by the author

- The Neutral Layer: a recommendation layer whose economics are not coupled to any brand's outcome
- The Indifference Test: a neutrality check; the layer must be indifferent to which product wins
- The callable layer: positioning a neutral verdict engine as a sub-agent callable by universal AI assistants and agentic commerce platforms
- Outcome-coupled revenue: the structural conflict of interest in recommendation systems monetized by advertisers
- Write-access to the rubric: capture defined as the ability to edit evaluation criteria, not just influence results
- Expiring relevance: personalization data should have a shelf life; stale relevance is misinformation
