Korea's Olive Young #1 is a sheet mask. America's is an anti-aging cream.

The same store sells a different Korea to America. For the first time this week we can place Olive Young's US storefront beside its Korean one — both sales-ranked best-seller charts from the same retailer — and the tops barely overlap. Olive Young Korea's #1 for 2026-W31 is a MEDIHEAL sheet mask; Olive Young US's #1 is Centellian24's Madeca cica anti-aging cream. It is the treatment-versus-routine split we saw at the ingredient level, now visible in what each country's cart actually holds.

What sits at the top of each chart?

Two different kinds of product. Korea's top five is masks and basics: MEDIHEAL sheet masks at #1 and #4, beplain's mung-bean cleanser at #2, a UNOVE hair mask at #3, a d'Alba sun cream at #5. Olive Young US's top five is creams and treatments: Centellian24's Madeca cream at #1, AESTURA's Atobarrier365 cream at #2, beplain's cleanser at #3, a SKIN1004 Centella serum at #4, a REJURAN ampoule at #5. The Korean shelf opens with things you use up fast and often; the US shelf opens with things you commit to.

Is there anything both markets buy?

Yes — and beplain is the clearest case. beplain's Mung Bean pH-Balanced Cleansing Foam is #2 in Korea and #3 on the US storefront, the same product charting near the top in both places, so this is not two disconnected markets. A cleanser is the crossover: an everyday, low-commitment step that travels without translation. We don't publish a single overlap count for the two charts, because Korea's and the US site's catalogs assign different product IDs to the same item — but hits like beplain show the lists share more than the top-five contrast suggests.

What does America's Olive Young lean toward that Korea's doesn't?

The clinical, anti-aging end. REJURAN — the PDRN skin-booster brand that also tops the worldwide chart — holds 5 of the US storefront's 100 slots but just 1 in Korea, and cica anti-aging creams (Centellian24's Madeca, SKIN1004's Centella line) sit high in the US top five. Korea, meanwhile, names hyaluronic acid on 10 of its top 100 to the US storefront's 4, and reaches for heartleaf more often. So the US storefront skews toward the results-promising treatments, and Korea's toward the hydrating, soothing everyday routine — the same direction the worldwide chart pointed, now confirmed on a US-specific signal.

What this does and doesn't tell you.

It is a first look at one US channel, not a verdict on American shelves. This is the first week Olive Young's US storefront is in our archive, so there is no week-over-week yet — treat it as a snapshot, not a trend. Olive Young US is a K-beauty-forward direct storefront, not all of US retail, and it carries more than skincare: tools, supplements and snacks appear in its top 100, and its catalog parses brands less cleanly than Korea's, which is why we lean on the well-identified top of the chart rather than precise brand-overlap counts. Both charts are the same retailer, sales-ranked for 2026-W31, so the merchandising is held roughly constant and what differs is closer to demand. What's already clear is the shape at the top: America reaches Olive Young for the cream; Korea reaches it for the mask.
