d'Alba's tone-up sun cream went from #24 to #1 in Olive Young Korea's suncare in eight days.

We read Olive Young's 'Top in Korea' ranking every day, tab by tab, and our weekly chart uses one of those reads. This week three of Korea's four big aisles kept last week's #1 — AESTURA in skincare, JUNGSAEMMOOL in makeup, MEDIHEAL in face masks. Suncare is the one that changed, and the daily reads show how.

Who leads Olive Young Korea's suncare now? d'Alba, since Nov 8.

Fact. d'Alba's Waterfull Tone-Up Sun Cream (Pink Correcting) in a 50 mL + 50 mL duo was #1 in the suncare tab on Nov 8 and again on Nov 10, the read our 2026-W46 chart uses. The same listing was #31 on Oct 13, #24 on Oct 31 and Nov 1, #7 on Nov 2, #4 on Nov 4 and Nov 5, #2 on Nov 7, then #1. d'Alba has a second listing at #4 this week, a purple tone-up duo.

The listing that climbed isn't the one that had been there.

Fact. d'Alba sells the same pink tone-up cream in a second set — a 65 mL Olive Young-only duo. That one was #6 on Oct 13 and still #7 on Nov 1. By Nov 10 it was #51. Observation. The two listings crossed: as the 50 mL duo rose, the 65 mL duo fell. Counted as a brand, d'Alba was already near the top — its best listing was #3 or #4 on every October read. Inference. When two sets of one product swap places like this, a change in which set is promoted or in stock is a likelier cause than a sudden change in demand. The ranking alone can't tell us which.

Before d'Alba, the top spot had been stuck — then it wasn't.

Fact. ROUND LAB's Birch Juice Moisturizing Sunscreen 1+1 set was suncare #1 on every daily read from Oct 13 to Nov 2 — 15 reads. After that, #1 went to SKIN1004's Hyalu-Cica Water-Fit Sun Serum set on Nov 4, back to ROUND LAB on Nov 5, to MEDIHEAL's Madecassoside sun serum on Nov 7, and to d'Alba on Nov 8. Four brands in five usable reads. In this week's chart, ROUND LAB's best place is #9.

Observation. The products trading #1 are tone-up and serum-type sunscreens, not classic sun creams. In our weekly reads, d'Alba's purple tone-up duo led this aisle every week from W31 to W37; ROUND LAB led from W40 to W45. Inference. Korea's suncare aisle has had long reigns and short scrambles. This week is a scramble that d'Alba came out of on top. Whether it settles into a run is a question for next week's reads, not this one.

Counter-argument, answered first. November is not sun season, so why read this aisle at all? Because the list does not go quiet in winter: it turned over four times in a week on the reads above, while the skincare #1 did not move once in 22 reads. We report the position; we don't claim the reason.

d'Alba is near the top of skincare too.

Fact. d'Alba's White Truffle First Spray Serum set has been #2 in Olive Young Korea's skincare tab on every daily read since Oct 29, behind AESTURA's Atobarrier 365 Cream. In the overall 'Top in Korea' list this week it is #3. In Japan, a d'Alba skincare set was #1 on Rakuten's daily beauty ranking on Nov 3 — a different product, on a different market's chart. We look at that day on Thursday.

How to read this

Olive Young 'Top in Korea' suncare tab, daily reads Oct 13–Nov 10 (KST). The Oct 19 read repeats Oct 18 and is counted once. The Nov 6 read failed our consistency check — part of the list did not line up with its product numbers — so it is left out of the counts above. Sets and sizes of one product are listed separately by the retailer. Daily chart position, not sales.
