K-Beauty Market Report — 2026-10-07

Generated 2026-10-07T12:15:47.446Z · tool v1.1.0 · sources: Wikimedia pageviews, Google Trends RSS, Reddit public feeds, Google News RSS (EN + KO), TikTok Creative Center, static watchlist · no paid APIs · no Amazon requests

1. Top Trending Ingredients

Ingredient interest — English Wikipedia pageviews · 16/16 tracked ingredients measured · 18/18 article requests OK · comparing 2026-10-06 vs 2026-10-05 (two complete days)

Complete table — all 16 measured ingredients (snapshot data). Biggest mover: Tranexamic Acid +67 views (+15.9%, now 488); biggest fall: Vitamin C -98 views (-12.8%). Highest absolute volume: Tranexamic Acid (488 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).

5. 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.

6. Auto-Summary

1. Source health: 6/6 sources produced data · degraded (documented fallback): Reddit community (SkincareAddiction + KoreanBeauty), TikTok Creative Center · no source failed
2. Ingredient interest: 16/16 tracked ingredients measured (Wikipedia pageviews, 2026-10-06 vs 2026-10-05). Biggest rise: Tranexamic Acid +67 views (+15.9%). Highest volume: Tranexamic Acid (488 views). Secondary Google Trends signal: none today (12/12 markets answered, 120 items scanned, 0 skincare matches).
3. Community pulse: 25 posts analysed; the most-discussed ingredient is Retinol / Retinoids (10 posts), with CeraVe the most-mentioned brand (5 posts).
4. News pulse: 200 headline(s) read across 2 quer(ies), 57 matched the lexicon. Most-covered: PDRN / Salmon DNA (35 headline(s)), brand Medicube (3 headline(s)) — editorial coverage, not consumer demand.
5. Biggest mover (pageviews 2026-10-06 vs 2026-10-05): up — Tranexamic Acid +67 views; down — Vitamin C -98 views. Community mention deltas: up — Retinol / Retinoids +4, down — Collagen -1.
6. Next action: watchlist holds 6 ASINs with price/rating/BSR still TODO (PA-API); while those wait, prioritise content around Retinol / Retinoids, the strongest demand signal available today (source: community mentions; social source: static-fallback).

Source status

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/dailytrends answers 404 (retired) and /trends/api/explore answers 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.mjs is 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.
