Korea's #1 is a different brand in each of its four beauty aisles

Olive Young publishes one overall best-seller list and a separate list for each category. The overall list is the one that gets quoted. This week it is led by a MEDIHEAL sheet-mask set — which is also the #1 in the face-mask tab.

Four aisles, four leaders

Fact. This week's #1 in each beauty tab: Torriden's Dive In hyaluronic acid serum in skincare, JUNGSAEMMOOL's Essential Skin Nuder Cushion in makeup, MEDIHEAL's Essential Mask Sheet in face masks, and ROUND LAB's Birch Juice moisturizing sun serum in suncare. Observation. No brand leads more than one aisle. Inference. "Korea's best-seller" is a fact about a category as much as a product: quote only the overall chart and you have quoted the mask aisle's winner.

Just below the top

MEDIHEAL holds both of the top two spots in face masks, and Torriden places its matching hyaluronic acid mask at #3 there. In suncare, ROUND LAB leads SKIN1004 and d'Alba. In makeup, JUNGSAEMMOOL's cushion leads rom&nd's lip tint and a WAKEMAKE eye palette.

How to read this

This is a single-week snapshot. We don't compare it with earlier weeks: our capture of these category tabs changed recently, so a different leader than before could reflect how we read the store rather than what shoppers bought. Sets, sizes and limited editions of the same product are listed separately by the retailer. We leave the Supplements tab out of this beauty read.
