Twenty brands share a top 30 — the leader holds four slots
A buyer looking at the Korean shelf usually wants to know who has to be displaced first. In our daily Olive Young category top 30, a single category is split between a median of twenty brands, and even the leading brand holds a median of four slots. The spread runs from twelve brands to twenty-six.
Almost no brand owns a Korean category outright. In our daily Olive Young category top 30, collected 3 November 2026, a category holds a median of twenty distinct brands, and the leading brand holds a median of four of the thirty slots. What varies instead is the brand count itself — twelve in the tightest category, twenty-six in the widest.
Thirty slots, twenty names
The first question a buyer asks about the Korean shelf is who has to be pushed out. Counting our daily Olive Young category top 30 by brand, collected 3 November 2026, there is usually no giant to push.
Across the 39 categories with a full top 30, a single category holds a median of twenty distinct brands. Thirty slots split between twenty names leaves roughly one or two slots per brand. The leading brand in a category holds a median of four.
Pooling all 41 categories, 412 brands share 1,209 slots. The widest footprint belongs to Shingmulnara at 27 slots, which is 2.2% of the total.
Only seven categories have a leader above six slots
Lining up the leading brand's slot count across the 39 categories, every value falls between two and eight. Four slots occurs in 11 categories and five in 12, so the middle is thick, and only seven categories go past six.
The tightest blocks sit in sun spray/patch and skincare sets, where Shingmulnara and Sulwhasoo hold eight slots each. Skincare devices follows with MEDICUBE AGE-R at seven. All three are categories where one brand ships a wide family of SKUs, or where tooling and certification keep newcomers out.
Cream sits at the other extreme. Kiehl's leads with two slots, and 22 of the 26 brands present hold exactly one. Inside one retailer, the shape of the shelf differs this much from aisle to aisle.

Twelve brands and twenty-six are different shelves
The brand count itself more than doubles across categories, from twelve to twenty-six. Baby & maternity and skincare devices sit at twelve each. Cream reaches 26 and shower & bath 25.
The narrow end has a pattern. In baby & maternity, long-established names such as Atopalm and Freiol hold five slots apiece, and in hair removal Gillette and Dorco take nine between them. Placement there tracks brand trust rather than formulation.
| Category | Brands in top 30 | Leader's slots | New entries | Median shelf price |
|---|---|---|---|---|
| Baby & maternity | 12 | 5 | 0 | ₩25,000 |
| Skincare devices | 12 | 7 | 1 | ₩290,000 |
| Hair removal | 13 | 5 | 3 | ₩26,510 |
| Sun spray/patch | 16 | 8 | 1 | ₩14,820 |
| Toner | 23 | 5 | 4 | ₩21,600 |
| Shower & bath | 25 | 2 | 1 | ₩18,700 |
| Cream | 26 | 2 | 10 | ₩29,600 |
The cell worth pausing on is the median price for skincare devices. At ₩290,000 it reads as a signal that the thin brand count comes from cost and certification rather than competition. Today's figures from the same tracking sit on today's ingredient signal.
A thin shelf is not an open shelf
Fewer brands sounds like an easier entry, and this data does not support that. In the ten categories with the fewest brands, the same tracking flags an average of 4.0 items as new entries. In the ten widest it is 3.8 — no real difference.
Case by case it wobbles further. Baby & maternity and deodorant both show zero new entries while sitting at the narrow end. Base makeup, meanwhile, pairs 17 brands with 10 new entries, the fastest turnover on a crowded-but-narrow shelf. Brand count describes the shape of a shelf; replacement speed has to be read separately.
Reducing entry odds to one number therefore gets it wrong. Brand count, the leader's slot count and new entries belong side by side. To lay those three against price band and launch month on one page, work it through the product planner.
234 of 412 brands appear in one category only
Counting brands horizontally changes the picture again. Of the 412 brands present, 234 appear in exactly one of the 41 categories. More than half of them arrived through a single specialist shelf.
Brands holding a single slot number 159, or 38.6% of the total. The multi-slot side is smaller than it looks, too: the ten largest brands hold 136 slots between them, 11.2% of 1,209.
That 11.2% is the number worth keeping. The Korean shelf is not carved up by a handful of owners, so the realistic target is one or two slots inside a chosen category rather than displacing an incumbent.
In short
- A category top 30 holds a median of 20 distinct brands, and the leader a median of 4 slots, as of 3 November 2026.
- Only seven of 39 categories have a leader above six slots, and the maximum anywhere is eight.
- Brand count more than doubles across categories, from 12 in baby & maternity to 26 in cream.
- Narrow categories average 4.0 new entries against 3.8 for the widest — brand count does not predict turnover.
- 234 of 412 brands appear in one category only, and the top ten brands together hold 11.2% of all slots.
