The answer is on the 4th floor of the Olive Young Seongsu Beauty Mansion.

If you prioritize “trying” over “buying” in Seongsu, head to Olive Young Beauty Mansion Seongsu（올리브영 뷰티 맨션 성수）. Opened in Bukseongsu（북성수）on June 30, 2026, this four-floor, approximately 500-pyeong experiential store is dedicated to hands-on beauty experiences.

Until now, the standard for shopping in Korea was “put everything from the shelves into your basket at the Olive Young（올리브영）in Myeongdong（Myeongdong）.” But this isn’t a store where you stand in front of the shelves trying to decide. With 3D skin analysis, AI image analysis-based makeup recommendations, and beauty device usage lessons, it is designed for you to walk in empty-handed and leave with “your own answers.”

What’s more, it has only been about a month since opening. It has barely appeared in Japanese travel information yet. Now is the freshest time to visit.

How to Explore the Four Floors

As the building’s name suggests, each floor is designed as an independent “room.” Since the order of the experience changes depending on whether you start from the top and go down or begin at the bottom and go up, it’s best to first familiarize yourself with the floor layout.

Floor	What’s There	Best For
1st floor	Open lounge＋shop-in-shop and pop-up stores	Those who want to discover currently featured brands
2nd floor	Services specializing in the color cosmetics category	Those who want to find colors that suit them
3rd floor	Services specializing in the skincare category	Those who want to choose based on their skin condition
4th floor	Beauty books and an LP listening break space	Those tired from walking／those waiting for their companions

The pop-up space on the 1st floor is where brands without permanent stores in the Seongsu area set up during new product launches and campaigns. In other words, the contents change depending on when you visit. It’s best to assume that not having “that thing you saw last time” is by design.

The 4th floor is the most distinctly Korean aspect of this store. An entire floor dedicated solely to books and LPs sits above the shopping floors. It also serves as an escape during the afternoon of a Korea trip, when you’ve walked until your energy runs out🔖

The Main Attraction: Newly Introduced Experiential Services

The 2nd and 3rd floors feature specialized services by category. The three new additions this time are as follows.

1️⃣ Advanced Derma Consulting（어드밴스드 더마 컨설팅）
A service that recommends K-dermocosmetics suited to you based on a 3D skin analysis. It transforms the task of comparing ingredient lists in front of the shelves into a process of working backward from your diagnostic results.

2️⃣ Color Fit Touch（컬러핏 터치）
Personalized makeup recommendations based on AI (artificial intelligence) image analysis. For those who used to make a separate appointment solely for a personal color analysis, this offers another option to complete the experience here.

3️⃣ Beauty Device Studio（뷰티 디바이스 스튜디오）
A studio inside the floor where you can actually pick up K-beauty devices and learn how to use them correctly. Beauty devices are expensive, and you cannot tell their size or weight from online shopping photos alone. Being able to hold one before buying is a major advantage.

In addition, Skin & Scalp Consulting（스킨·스칼프 컨설팅）, Quick Touch-Up（퀵 터치 업）, and Find Your Color（파인 유어 컬러）are also available. Having a pathway that lets you get your scalp checked as well is an experience you are unlikely to find at Japanese drugstores.

Editor's note / The local information is the most up to date source for service hours and check-in procedures. Since analysis services take time, the right approach is to set aside time for them as a specific purpose, rather than trying to fit them in while shopping.

Why “North Seongsu”?

The K-beauty buzz in Seongsu（ソンス・성수）had previously centered around Yeonmujang-gil（연무장길）. The Beauty Mansion was created as an attempt to organically connect that flow to North Seongsu as well.

According to CJ Olive Young, the concept is to maximize brand visibility, expand points of contact with international visitors, naturally direct people to showrooms and pop-ups throughout Seongsu, and build an open K-beauty ecosystem in which the entire commercial district coexists (Herald Economy report, June 29, 2026).

For travelers, the significance is simple. Rather than returning home after visiting this one building, it is more efficient to use it as a starting point for touring Seongsu's showrooms. It has become an area worth setting aside a half-day block for.

What to know before you go

The opening promotion was limited to the five days from June 30 to July 4. Merchandise such as reusable bags and pouches was given away according to purchase amount tiers, with additional discounts also offered at the same time—but this has already ended. It is better not to plan your visit around “going for the merchandise.”

The reason it is worth going now is that you can try the experiential services while the crowds are still predictable. The buzz immediately after opening has died down somewhat, and this is a window of opportunity before the location is featured in Japanese guides. Conversely, once more introductions appear, waiting times for diagnostic services may change😳

• If you are going for the experiences, set aside a time slot from the morning to early afternoon
• Visit with the expectation that the pop-up on the first floor changes periodically
• Factor in the fourth floor as a lounge floor that you can enter even without making a purchase

Summary

Beauty Mansion Seongsu is “a place to make decisions,” not “a place to shop.” If you have a reason to use any of these three services—the Advanced Derma Consulting 3D skin analysis, the AI-based Color Fit Touch, or the Beauty Device Studio where you can try the devices—you have more than enough reason to visit.

On the other hand, if your only goal is to buy items in bulk, the large stores in Myeongdong or Gangnam are faster. The deciding factor in whether to include it in your Korea trip itinerary is whether “you want to determine on-site what suits you.” On your next trip to Korea, try setting aside half a day for the Seongsu area and planning your visit around these four floors✨

Frequently Asked Questions

Where is Olive Young Beauty Mansion Seongsu located?

It is located in Seoul’s Bukseongsu (북성수) area. This area extends north from Yeonmujang-gil, the center of Seongsu’s K-Beauty scene, and features approximately 500 pyeong of total floor space across four floors. It is situated in a location intended to be visited together with the nearby showrooms and pop-ups.

Are the experiential services available in Japanese?

For language support, it is safest to check the official information on-site. The Advanced Derma Consulting 3D skin analysis and the Color Fit Touch AI makeup recommendation service display the diagnostic results on-screen, so the setup makes it relatively easy to understand the results even if your language skills are not perfect.

Can I still receive the opening commemorative merchandise?

No. The opening promotion, which included reusable bags and pouches as gifts along with additional discounts, was limited to the five days from June 30 to July 4, 2026, and has already ended. Please check the in-store information available at the time for current benefits.
