The NARS Seongsu pop-up is running at Musinsa Megastore Seongsu to mark the launch of ‘Insatiable Liquid Blush.’ For visitors tracking Seongsu Pop-ups in July 2026, this event is especially useful because the core details are clear: it opened on July 11, 2026, and is scheduled to operate through July 24, 2026.1
The pop-up centers on product testing and offline brand experiences built around the new liquid blush line. Musinsa’s official content lists the venue as Musinsa Megastore Seongsu, 62 Seongsui-ro, Seongdong-gu, Seoul, with operating hours from 11:00 a.m. to 10:00 p.m.2
NARS Seongsu Pop-up Dates, Location, and Visit Basics

The most important planning detail is the limited operating window. The NARS pop-up began on July 11 and continues until July 24, 2026, giving visitors a two-week period to see the space in Seongsu.3 Since the current date is July 19, 2026, the event is already open and still within its scheduled run.
The location is Musinsa Megastore Seongsu, which Musinsa identifies as 서울 성동구 성수이로 62, or 62 Seongsui-ro, Seongdong-gu, Seoul.2 That official address is the most useful detail to copy into a map app, because several beauty, fashion, and lifestyle pop-ups can cluster around Seongsu at the same time.
The stated operating hours are 11:00 a.m. to 10:00 p.m.2 No separate reservation rule is included in the supplied source material, so readers should not assume booking is required based on the available information. The safest practical approach is to use the confirmed dates, venue, and hours as the baseline, and check the Musinsa event page before traveling if timing is tight.
What You Can Do at the Insatiable Liquid Blush Pop-up
The event was created for hands-on discovery of NARS ‘Insatiable Liquid Blush.’ CMN describes the pop-up as a place where visitors can directly experience the new product, with product testing, participatory content, and purchase benefits forming the offline brand experience.3
The reported activity zones include Liquid Color Play, a Liquid Blush Discovery Zone, a photo zone, a lucky draw, and touch-up makeup service.1 These details make the event more than a retail display: it is structured around trying shades, exploring the product texture and finish, and using the brand space for photos and small participation-based benefits.
Two Musinsa-exclusive colors are also part of the visit draw. The shades ‘Itsy Bitsy’ and ‘Orgasm Fantasy’ are introduced by Musinsa as exclusive colors, and they are connected to the pop-up experience and purchase benefits.2 For shoppers deciding whether to visit in person, these exclusives are the strongest product-specific reason to prioritize this location over a general online search.
Musinsa also announced gift benefits based on purchase quantity and included a makeup show schedule in its official content.2 The exact gift tiers and makeup show times are not included in the provided source summary, so visitors should rely on Musinsa’s official event content for those details before planning around a specific show.
A celebrity-related moment also helped draw attention to the pop-up. Chosun Ilbo reported that actor Moon Ga Young attended the NARS ‘Insatiable Liquid Blush’ pop-up opening event at Musinsa Megastore Seongsu on July 13, 2026.4 Separately, CMN reported that NARS had selected Moon Ga Young as the brand’s new model and released campaign images for the new product under the ‘EMOTIONAL FLUSH’ concept.5
NARS linked the model announcement to Moon Ga Young’s image as an actor. A NARS brand representative said the brand was pleased to appoint Moon Ga Young, describing her as having “artistic sensibility and unique charm.”5 In practical visit terms, this background explains why campaign visuals and the new blush launch are closely connected, but the core visitor value remains the product trial experience at the Seongsu venue.
How to Plan a Focused Visit
Because the pop-up is scheduled only through July 24, 2026, visitors who want to go should treat the remaining days as limited.1 The event hours, 11:00 a.m. to 10:00 p.m., provide a broad daily window, but the source material does not provide crowd forecasts or entry rules.2
If your main goal is shade testing, start with the product experience areas: Liquid Color Play and the Liquid Blush Discovery Zone.1 If your goal is a purchase, check the Musinsa-exclusive shades ‘Itsy Bitsy’ and ‘Orgasm Fantasy’ first, because exclusivity is the clearest shopping distinction identified in the official content.2
For visitors comparing multiple Seongsu Pop-ups, this NARS event is best approached as a beauty product trial stop rather than a general exhibition. The available facts point to makeup testing, participatory content, purchase benefits, a photo zone, lucky draw activity, and touch-up makeup service.1 That makes it suitable for people who want to test blush shades in person, look at the campaign concept, or combine a short beauty visit with other Seongsu plans.
