K-Beauty Market Report — 2026-09-16

No skincare-specific trend in today's feed. Google Trends' daily RSS is news- and sports-driven; skin-related queries simply did not surface in this window. No data is inferred or fabricated — the filter runs on real feed items only.
Monitored lexicon: 127 skin-related terms and brands · endpoint health: retired keyword endpoint skipped (HTTP 404).

4. Competitor Watchlist
Tracked ASINs: 6 · live metrics: TODO (PA-API) · Amazon requests made by this tool: 0
Our picks are cosmetic product recommendations, not medical prescriptions. Some links are affiliate links — we may earn a commission at no extra cost to you.

Why the columns are empty: Amazon presented an IP throttle after earlier scraping, so v1 makes no Amazon requests at all. Price, rating and BSR will be populated through the official Product Advertising API (PA-API) in a later version — the ASINs above are pre-wired for that switch.
5. Auto-Summary
- Source health: 4/4 sources produced data · degraded (documented fallback): Reddit community (SkincareAddiction + KoreanBeauty), TikTok Creative Center · no source failed
- Trend mover: none. 12/12 Google Trends markets answered (120 items scanned) but no skin-related query surfaced — a dry day for this feed, reported as-is.
- Community pulse: 25 posts analysed; the most-discussed ingredient is Sunscreen (unspecified) (7 posts), with CeraVe the most-mentioned brand (5 posts).
- Biggest mover vs 2026-09-15: up — Sunscreen (unspecified) +2 (now 7); down — Hypochlorous Acid -1 (now 0).
- Next action: watchlist holds 6 ASINs with price/rating/BSR still TODO (PA-API); while those wait, prioritise content around Sunscreen (unspecified), the strongest demand signal available today (social source: static-fallback).

Methodology & caveats
- Trends: Google Trends publishes no global feed and no per-keyword RSS, so "worldwide" is 12 markets queried individually and aggregated; a term ranking in more markets ranks higher. The retired keyword endpoint is probed once and skipped on 404.
- Community: the public JSON endpoint is currently blocked (HTTP 403 for non-browser clients); the Atom feed is the documented fallback, Score shows engagement (upvotes + comments) where Reddit shares both counts; "—" means Reddit shared no counts for that row.
- Social: TikTok Creative Center hashtag rankings are gated behind an authenticated session, so the curated list in
src/lib/lexicon.mjsis used and the probe verdicts are printed as evidence. - Watchlist: price/rating/BSR stay
TODO (PA-API); this tool never contacts Amazon. - Summary: rule-based only — five lines, each derived from the values above, never generated prose.
