Olive Young N Seongsu: what's inside and how to shop it
Olive Young N Seongsu is the chain's biggest single store and its test bed for what a K-beauty flagship can be, according to https://www.glowolive.net/ko/oliveyoung-n-seongsu/. Set inside the Factorial Seongsu building, it spreads across roughly 4,628 square meters (about 1,400 pyeong) on five floors, and CJ Olive Young has framed it as a showcase for where the brand is heading next rather than just a bigger branch store.
Floor 1 is a playground-style space with a café, rotating pop-ups and a merchandise corner. Floor 2 covers colour cosmetics and fragrance, with a makeup studio and a men's grooming section. Floor 3 is dedicated to skincare and wellness, anchored by a skin-diagnosis studio that visitors line up for before opening. Floors 4 and 5 are mostly VIP and partner-brand space, plus a 25th-anniversary archive exhibition — worth a look if open, but not where you shop.
Across reviews, the free skin diagnosis and the well-stocked, well-organised testers with proper wash stations come up again and again as the highlight, alongside praise for how often the pop-ups and exhibitions rotate. The complaints cluster too: weekend crowds that spill into a line outside the building, restroom waits reported near 25 minutes, and more than one visitor saying the specific skincare item they came for was out of stock despite the store's size. Google's rating sits around 4.3 out of 5 from 541 reviews as of August 2026.

One extra logistics note: instant tax refunds are usually capped per day per store based on total spend, so if you're planning a big haul it can help to split payments. Confirm the exact cap at the counter on the day, since it can change.
