Where K-beauty already won on America's shelf — and where it's never shown up

A single average — Korea holds 12.1% of the positions on America's four mainstream beauty charts — tells you almost nothing about where Korea actually lives on the shelf. Split those 340 positions by what the product is, and the flat line pulls apart into strengths that over-index hard and aisles with no Korean presence at all.

Where it already won

The strengths are the small, Korea-native formats. K-beauty holds 25% of patch & mask positions, 23.7% of serum & ampoule, and 19.2% of sun care — each roughly double its overall share. These are the routine steps K-beauty popularized, and on America's charts they punch well above the category's weight. This is the real arrival: not a broad 12%, but a few aisles Korea helped invent and now over-indexes on.

One of those strengths is solid. The others are thin.

The number that matters isn't the share — it's how many brands hold it. Serum & ampoule's 23.7% is spread across seven Korean brands: a category Korea genuinely occupies, resilient to any one brand slipping. Patch & mask's 25% rests on two; the sets-and-kits share, on one. A share built by a single brand is a position, not a category — one delisting and it halves. Same colour on the chart, very different foundations underneath.

Where it's just ordinary

The biggest aisle on the US skincare shelf is moisturizer — 61 of the 340 positions — and there Korea is exactly average: 11.5%, sitting right on the overall line, held by four brands. The largest, most-contested shelf is the one where K-beauty neither leads nor lags. It simply blends in.

Where it's never shown up

And then the blanks. This week Korea holds zero positions in eye care — the one empty aisle visible on the chart — and, just below the chart's cut, none in body care either, with a single position in lip. But zero here has a narrow meaning: no Korean product charted in that type on these four lists this week. It is not proof Americans won't buy a Korean eye cream — only that none reached these charts. Whether Korea hasn't built those formats for the US or simply didn't chart this week, our data can't separate the two, so we read a blank as open, not lost.
