Market intelligence
K-Beauty Market Report — 2026-10-18
Our guides and picks are cosmetic curation for education only — not medical advice. Skin varies person to person: patch-test new products and see a dermatologist for persistent or concerning issues.

1. Top Trending Ingredients
Ingredient interest — English Wikipedia pageviews · 0/16 tracked ingredients measured · 18/18 article requests OK · comparing 2026-10-17 vs 2026-10-16 (two complete days)
No ingredient pageview data today. Every tracked article request failed; the per-title log below is the evidence, and nothing is estimated to fill the gap.
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).

5. Competitor Watchlist
Tracked ASINs: 6 · live metrics: TODO (PA-API) · Amazon requests made by this tool: 0

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.
6. Auto-Summary
- Source health: 5/6 sources produced data · degraded (documented fallback): Reddit community (SkincareAddiction + KoreanBeauty), TikTok Creative Center · failed: Wikimedia pageviews (ingredient interest)
- Ingredient interest: no pageview data today — every tracked article request failed (see section 1). Secondary Google Trends signal: 12/12 markets answered (120 items scanned), 0 skincare matches.
- Community pulse: 32 posts analysed; the most-discussed ingredient is Sunscreen (unspecified) (13 posts), with CeraVe the most-mentioned brand (9 posts).
- News pulse: 200 headline(s) read across 2 quer(ies), 57 matched the lexicon. Most-covered: PDRN / Salmon DNA (33 headline(s)), brand Medicube (4 headline(s)) — editorial coverage, not consumer demand.

- 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 (source: community mentions; social source: static-fallback).

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.
