COSRX
COSRX did not ask for this and is not a client. We ran it on a brand everyone in the category knows so you can check the result yourself.
Where you stand
Ten questions were asked. Four of them contained the word "COSRX", so being mentioned back proves nothing. The six that did not are the ones that decide whether a new customer finds you.

Brand-owned pages are being pulled into category answers
Three of the six discovery answers cited a brand's own website. Anua, Biodance and Beauty of Joseon. In two of those three the brand that owned the cited page was also named in the answer. Biodance was cited and not named, so this is a strong pattern rather than a rule.
cosrx.com was cited exactly once across all ten questions, on the one that already said the word "COSRX". Your own pages are not being retrieved for the questions where a new customer is deciding. That is a content and structure problem, not a product problem.
A Singapore publication is deciding a Singapore answer
The sunscreen question cited harpersbazaar.com.sg and the answer said in as many words that "Singapore beauty editors specifically highlight it". Local editorial is a reachable, and currently unclaimed, route into these answers.
What we cannot move
The part most providers leave out.
Three of the ten questions returned no citations at all
Both head-to-head comparisons and the reputation question came back with zero sources. Those answers came from what the model already holds, not from anything it went and read.
Publishing will not move them in the short term, and anyone who tells you it will is guessing. Only the category and constraint questions had live retrieval, and those are the addressable ones, and every action below is tied to one.
What to do
Ranked by expected value. Each one names the questions it targets and the evidence behind it. A free check carries three; a Core plan carries five, a Pro plan ten.
Build a barrier-repair moisturiser page that can be cited
The dry-skin question named AESTURA, ILLIYOON, Dr. Althea, Beauty of Joseon and Anua, and not COSRX. The answer justified its pick by pointing at a third-party ranking. COSRX has products that belong in that answer but no retrievable page framing them for the barrier-repair use case in the language the question uses.
Targets Q2 · evidence: allure.com cited, COSRX absent
Own the humid-climate sunscreen question locally
Beauty of Joseon took first and fourth place on the sunscreen question, supported by the Singapore edition of Harper's Bazaar. This is a market-specific answer decided by a market-specific publication. A page written for humid-climate daily wear, plus a push for local editorial coverage, targets the one question where geography is doing the work.
Targets Q3 · evidence: harpersbazaar.com.sg cited, COSRX absent
Make the sensitive-skin range legible as a range
The sensitive-skin question returned eight brands, each with a named product line: "Madagascar Centella line", "Atobarrier 365 line", "R.E.D Blemish line". The assistant is reasoning in lines, not products. COSRX was not named. Grouping the relevant SKUs into a clearly named, clearly described line is the structural change that makes a brand eligible for this answer.
Targets Q4 · evidence: 8 competitors named by product line, COSRX absent
Evidence
All ten questions, what came back, and what each answer cited. Full verbatim answers are attached to the email this link came with.
"If you have oily, acne-prone skin, my top Korean brand pick is Anua…" COSRX placed second, described as "Best for targeted acne care".
Questions that named COSRX in the question
"If your main goal is acne, I'd generally pick COSRX over Beauty of Joseon."
"If you can only buy one, I'd generally choose COSRX Snail Mucin because it's more useful for hydration and barrier support."
"Yes. COSRX is generally a good skincare brand…" with the caveat "COSRX isn't automatically good for everyone."
How this was measured
| Assistant | One of the four general-purpose assistants we track, on its standard consumer web app, not a developer API. Which one is named in your own report. |
| Questions | 10, each asked in its own separate session |
| Session state | Memory off, no chat history, no custom instructions |
| Market | Singapore. The assistant returned SGD pricing and local retailers unprompted |
| Date | 10 August 2026 |
Memory off matters. Asked the same question on a signed-in account with memory on, the same assistant put a different brand first and cited a different set of sources. A reading taken in your own account tells you what AI says to you, not to a stranger deciding what to buy.
AI answers vary between sessions and change over time. This is a reading taken on one date, not a permanent score. Competitor brands appear because the assistant named them; we report that as fact and do not evaluate their products. See Method & Disclaimer.
