B2C Case Study
Premium Skincare Buyers (Japan & South Korea)

What the client needed
Two hundred women (25–49) in Japan and South Korea who buy premium skincare: routines, ingredient awareness, and reaction to new concepts.
Why it was hard
Two of the world's most demanding beauty markets, distinct beauty cultures, local-language surveys, concept-test cells — in 10 field days.
How we ran it
- Locally built questionnaires: Separate Japanese and Korean instruments with in-market beauty researchers.
- Spend-based screening: Premium defined by actual spend, keeping aspirational buyers out of the base.
- Monadic concept cells: Clean launch-readiness reads per concept.
- Tighter QC: Speeder and straight-lining thresholds set for detail-oriented respondents.
