1. Top Trending Ingredients
Ingredient interest — English Wikipedia pageviews · 16/16 tracked ingredients measured · 18/18 article requests OK · comparing 2026-09-29 vs 2026-09-28 (two complete days)
| # | Ingredient | Views 2026-09-29 | Prev day 2026-09-28 | Δ | Δ % |

| 5 | Salicylic Acid (BHA) | 885 | 809 | +76 | +9.4% |

| 10 | Panthenol (B5) | 82 | 84 | -2 | -2.4% |
| 11 | Vitamin C | 758 | 777 | -19 | -2.4% |
| 12 | Centella Asiatica (Cica) | 377 | 387 | -10 | -2.6% |
| 13 | Hyaluronic Acid | 402 | 418 | -16 | -3.8% |
| 14 | Tranexamic Acid | 483 | 526 | -43 | -8.2% |
| 15 | Squalane | 82 | 96 | -14 | -14.6% |
| 16 | Benzoyl Peroxide | 155 | 236 | -81 | -34.3% |
Complete table — all 16 measured ingredients (snapshot data). Biggest mover: Glycolic / AHA +112 views (+58.0%, now 305); biggest fall: Benzoyl Peroxide -81 views (-34.3%). Highest absolute volume: Glycolic / AHA (305 views).
Proxy note: Wikipedia pageviews measure public curiosity about an ingredient — not sales, not search volume, not social chatter. The two days compared are both complete days, so a partial "today" bucket never distorts the delta.
Secondary signal — Google Trends daily RSS (news-driven feed, low skincare yield by design)
Markets queried: 12/12 answered · items seen: 120 · skincare-matching trends: 0
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).

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.

Methodology & caveats
- Trends: the primary signal is ingredient interest measured as English Wikipedia pageviews for 18 tracked articles (Wikimedia pageviews API: public, no key, no cookie), comparing two complete days. Pageviews are a curiosity proxy — not sales, not search volume. Google Trends RSS is kept as a secondary signal only: it publishes no global feed and no per-keyword RSS, so "worldwide" is 12 markets queried individually, and its daily feed is news/sports-driven (0 skincare matches on 2026-09-15 → 2026-09-17). Google Trends' informal keyword endpoints were re-probed on 2026-09-17:
/trends/api/dailytrendsanswers 404 (retired) and/trends/api/exploreanswers 429 (throttled), so neither is used. - Community: the public JSON endpoint is currently blocked (HTTP 403 for non-browser clients), so 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, never an error. Titles keep their source wording; feed-truncated titles are restored from the post URL where possible and stay linked to the full post.
- 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. - News: Google News RSS headlines (English + Korean queries) are filtered against the same ingredient/brand lexicon and printed with publisher and timestamp. Editorial coverage is a coverage signal, not consumer demand or sales volume; unmatched headlines are counted as read-but-skipped, never padded into the table.
- Watchlist: price/rating/BSR stay
TODO (PA-API); this tool never contacts Amazon. - Summary: rule-based only — every line derived from the values above, never generated prose.
