How We Source

Last updated Sep 30, 2026

Much of the most useful skincare information from Korean dermatologists, pharmacists, cosmetic scientists and estheticians exists only in Korean-language videos. We research it and report it to English readers — the way any publication reports on expert findings, in our own words, with the facts checked against the original source.

1. We start from what readers ask

Topics come from what English speakers actually search for, not from a list we invented. A topic is only written if people are searching for it.

2. We only draw on experts who state their own credential

We use a YouTube channel as a source only if its own name or description states the person's profession — for example “피부과 전문의” (board-certified dermatologist), “약사” (pharmacist), “화장품 연구원” (cosmetic scientist) or “피부관리사” (licensed esthetician). We also skip channels with fewer than 10,000 subscribers, which in our checks were mostly shop promotion channels. Channels that re-upload or summarise other people's clips, brand channels, and videos marked as sponsored are excluded. In the video itself, the person speaking must be the channel's own host, or a guest who states their credential.

3. We report the facts, not the video title

Each video is watched and listened to in full and logged statement by statement. Titles and view counts are only used to find candidate videos, never as source material. Every article is written up fresh, in our own words — never a translated transcript.

4. At least two experts per article

Every article draws on at least two different experts. We never turn a single video into an article.

5. A second check, fact by fact

After an article is written, a separate review compares every reported fact against the original Korean statement it came from (so nothing is made stronger than what was said, and no detail is attached to the wrong product or person) and checks that nothing in the article goes beyond what our research found. Articles that fail are not published.

6. Skincare you can do yourself

We report what experts say about skincare and cosmetic products, home beauty devices and everyday care habits. We do not cover prescription or pharmacy medicines, supplements, clinic procedures or surgery. Nothing here is medical advice — see our Disclaimer.
