Housed on the ground floor ('Youtiful Finder'). Bypasses general surface-skin charts by deploying an advanced AI camera that maps the unique color matrix of your eyes and irises, outputting a precise pigment report to map your perfect tonal shadow and lip palettes.

Located on the second floor, a dedicated touch-up station where resident professional artists provide instant, 15-minute targeted styling sessions (Base, Eye, or Skincare tracks) using the diagnostic data to lock in the iconic Jung Saem Mool 'born-as-it-is' structural skin look.

The only dedicated flagship where you can explore and experiment with the brand's entire sub-portfolio simultaneously—including the clean vegan line Begins by Jung Saem Mool, the specialized Jung Saem Mool Kids, and elite hair care from Salongzip.

If you want to experience the highly coveted 90-minute K-Beauty Group Class or a full 60-minute 1:1 Private Makeup Consultation, book your slot weeks in advance via global travel portals. These premium packages typically include curated makeup gifts valued up to 70,000–87,000 KRW, making the experience exceptionally cost-effective.

If you have scheduled a premium 1:1 or group beauty lesson, arrive completely bare-faced. If you're coming straight from another itinerary track, arrive 10–15 minutes early to utilize the second floor's professional cleansing zones to clear away oxidized foundations before the session starts.

Don't skip the upper levels. After completing your personal color tracking, take your customized photo booth token to the 3rd floor for a personalized lighting shot, then head to the 4th-floor 'Youtiful Terrace' to relax and enjoy panoramic rooftop views over Seongsu's main fashion artery.
