The NARS Seongsu pop-up is an in-person launch event for NARS’ new Insatiable Liquid Blush at Musinsa Megastore Seongsu. Running from July 11 to July 24, 2026, it is one of the more product-focused Seongsu Pop-ups for beauty shoppers who want to test shades, join participation programs, and see Musinsa Beauty-exclusive colors tied to NARS’ arrival on the platform.1
NARS Seongsu Pop-up: Dates, Hours, and Location

The pop-up is being held at Musinsa Megastore Seongsu, with NARS Cosmetics Korea’s official Instagram notice identifying the location as the first floor of the store.2 For visitors planning a route, this is the key confirmed venue detail available in the source material.
The event period is July 11 to July 24, 2026. Daily operating hours are 11:00 a.m. to 10:00 p.m., but mission-based programs are available only until 8:00 p.m.1 That distinction matters: arriving near closing time may still leave room to look around, but it could limit access to activities connected to missions or participation rewards.
The pop-up is linked to the launch of Insatiable Liquid Blush. Musinsa Beauty also held an online showcase on July 11, 2026, to mark NARS’ entry into the platform, with the new liquid blush presented as part of that launch.3 In practical terms, the online showcase was the launch-day digital moment, while the Seongsu pop-up is the physical experience continuing through July 24.
What Visitors Can Do at the NARS Seongsu Pop-up
The reported setup is built around product discovery rather than simple product display. On-site elements include a Liquid Color Play zone, a Liquid Blush Discovery Zone, a photo zone, a lucky draw, and touch-up services by professional makeup artists.1
Other reported experience points include a color preference test, product trial areas, a photo program, and touchscreen kiosk game-style content.4 Together, those features suggest that the pop-up is designed for visitors who want to compare shades, try the new blush format, and take part in interactive brand activities.
If your main purpose is testing the product, plan enough time for the discovery areas rather than treating the visit like a quick counter stop. The source material does not provide a separate reservation method, service fee, or queue rule for the professional makeup artist touch-up service, so visitors should confirm the day’s operating conditions at the venue.
The mission cutoff is also important. Because mission programs are available until 8:00 p.m., shoppers who want the fullest participation experience should arrive well before that time. The published 10:00 p.m. closing time should be read as the overall pop-up closing time, not as a guarantee that every activity will remain open until the end of the day.1
Exclusive Shades and Purchase Notes
A major product point is the release of two Musinsa Beauty-exclusive shades: Orgasm Fantasy and Itsy Bitsy. These colors were introduced through Musinsa Beauty’s July 11 showcase as exclusive shades connected to the NARS launch on the platform.3
NARS Cosmetics Korea’s official Instagram summary also notes that two shades are being unveiled first through Musinsa, reinforcing the pop-up’s role as a launch-linked product experience rather than a general brand display.2 Separate reporting mentions two Musinsa-exclusive colors and gift promotions for purchasing customers during the event period.4
The available source material does not specify purchase thresholds, gift quantities, or detailed eligibility rules for those promotions. If the purchase benefit is your main reason for visiting, check the current conditions at Musinsa Megastore Seongsu or through Musinsa Beauty before deciding what to buy.
For shoppers comparing online and offline options, the simplest distinction is clear: Musinsa Beauty is the retail platform context, while the Seongsu pop-up is the hands-on product experience. Hyundai Economic Daily reported that Musinsa Beauty added NARS as part of an expanded luxury makeup lineup, with the Seongsu pop-up positioned as a customer contact point around the launch.5
