medicube now holds 11 of TikTok Shop's top 20 skincare listings.

TikTok Shop is the fastest-moving K-beauty shelf we track. Its ranking is an estimate of sales from a commercial data provider (TikTok Shop · data via Kalodata), not a list TikTok publishes, so we keep it on its own scale. This week the story on it is one brand's width.

How much of the top 20 is medicube? Eleven listings.

Fact. In 2026-W46, 11 of the 20 highest-ranked listings in TikTok Shop's US skincare ranking are medicube's, including #1, #2 and #3: its NAD+ EGF firming serum, Zero Pore Pads and a five-step set. A week earlier, medicube had 5 of the top 20. In the weeks we have read this list — W34, W35 and W40 to W46 — its top-20 count ran from 5 to 9 until now.

Fact. Across the full top 100, medicube has 27 listings, up from 23 in W45 and level with W42, the highest we have recorded. It has 5 of the top 10.

Fact. Week by week, medicube's count in the top 20 has been: W34 7 · W35 6 · W40 6 · W41 6 · W42 9 · W43 9 · W44 7 · W45 5 · W46 11. Its count in the top 100: 22 · 20 · 20 · 26 · 27 · 20 · 22 · 23 · 27. Observation. The top-100 count moves in a band of about 20 to 27; the top-20 count is what jumped this week. The top-100 count rose by four; the top-20 count more than doubled.

Last week's big jump didn't hold.

Fact. In W45, ongredients' BakuGlow Capsule Lotion jumped to #2 — we wrote about it then. This week that listing is not in the top 100. The brand's only listing left is a different lotion, at #77. Observation. A listing that reaches #2 and is gone a week later moved like a single push — a campaign, a creator video, a stock run — more than like a steady seller. Inference. On this ranking, one week at the top proves reach, not staying power. medicube's case is the opposite: many listings, every week, and this week more of them high up.

The rest of the top ten barely changed hands.

Fact. Nine of the top ten listings are from Korean brands, the same as last week. Besides medicube they are epais (#4), Dr.Melaxin (#7 and #8) and Sungboon (#10). The one non-Korean listing is GOPURE's eye gel at #9. Across the whole list, at least 65 of the 100 listings are from brands in our Korean ledger. Dr.Melaxin has nine listings in the top 100, its best at #7, up from #10 a week ago.

Observation. When one brand fills more of the top 20, the other brands have fewer places to land there. This week, medicube's gain from 5 to 11 top-20 listings came while ongredients, Dr.G and BASED, all in last week's top 20, fell out of it.

What this does and doesn't say about sales.

Counter-argument, answered first. An estimated ranking can move because the estimate moved. We can't rule that out, and we don't publish the provider's revenue estimates. What we report is position on the ranking as delivered each week, compared only between weeks we actually re-read. That is enough to say medicube occupies more of the top of this list than at any point we have seen. It is not enough to say how much it sold.

How to read this

TikTok Shop US, skincare, top 100 by estimated sales, 2026-W46 vs earlier weeks we re-read (W36–W39 repeated W35 and are not counted). TikTok Shop's all-category list was not re-collected this week, so this story uses the skincare list only. Brand = brand named in the listing; 16 listings this week could not be read cleanly enough to attribute to a brand, so brand counts are floors. Listing position, not sales.
