What we actually do, step by step
- Collect. We pull the public listing data for every Medicube product on Amazon in the United States: title, images, ingredient list, rating, review count, Best Sellers Rank and the rounded "bought" badge Amazon shows.
- Date everything. Every figure on this site carries the date we read it. Amazon changes constantly, so an undated number is a useless number.
- Rank by evidence we can point at. Ratings and review volume, not marketing copy and not commission. The how we rank page has the exact method.
- Write the honest version. Including the texture complaints, the one-star themes and the products where a rival simply wins.
- Publish the caveats with the claim. Sample sizes, what a flag does and does not mean, and where our data stops.
Where our numbers come from
- Ratings, review counts, Best Sellers Rank, "bought" badges: the public Amazon product page (read between 2026-09-29 and 2026-09-30 for ratings, read between 2026-09-29 and 2026-09-30 for rank and badges). Ingredient lists: the manufacturer's own site, cross-checked against the Amazon listing where possible.
- Prices: the Amazon price on the date shown beside each price. Not live, and never presented as live.
- Buyer sentiment: a sample of customer reviews per product, read and summarized in our own words. It is a sample, not a survey.
- Brand background: public reporting and company filings, cited on the page where we use it.
When we get it wrong
We will. Listings change, formulations change by market and batch, and automated data has failure modes. If you spot an error, tell us and we will correct it and say what changed. We would rather be corrected than be quietly wrong.
Our conflicts of interest, stated plainly
We earn affiliate commission when you buy through our links. Commission never decides a ranking or a verdict: rankings are computed from rating and review volume before any commercial consideration. Medicube has never paid us, sent us product, or been shown a page before publication.
