FAQ

How did kbeautytmi choose these picks?
Every product on this list is a K-beauty item we track in our weekly retail rankings. We start from what is actually charting across retailers, then curate — so the list is grounded in observed data, not editor taste alone.
What does the data badge on each product mean?
It is that product's best observed rank in our latest weekly snapshot — for example “#2 on Amazon.” If a product has no badge, we did not observe it on a tracked chart that week, and we do not invent one.
Are these affiliate links?
Shop links point to the retailer's product page. Where affiliate programs apply, links may be monetized in future; they are always marked and never change which products we include.
