★ This week's finding
Korea's top 20 and the US top 100 share almost nothing.
Same store. Same week. Different planets.
A map of how Korean skincare moves from Korea to global shelves — and a radar for how products already breaking out in the US expand into the next sales channel. We snapshot every channel's rankings weekly and archive them permanently; rankings can't be recovered retroactively, so this history exists nowhere else.
Same store. Same week. Different planets.
One lead read, one follow-up, one official launch signal — selected from the archive.
Rankings can't be collected retroactively. Every week we don't capture is gone permanently — which is why the archive, not the analysis, is the moat.
