Makeup primer reputation and influencer endorsement
Multiple reviews mention Korean makeup artists and YouTubers recommending it as a makeup base, and customers discovering it through salon use or online buzz (소문듣고 구매했는데, used in Korean makeup salons). This social proof drives trial conversion.
Repurchase and stockpiling behavior
Customers explicitly state they are on their 3rd-4th+ bottle and purchase in bulk (ストックしてます, 벌써 4병째 구매중). This indicates strong product-market fit and habit formation among core users.
Bundle value proposition (refill included)
Multiple reviews highlight appreciation for receiving a full refill bottle with the main product (리필을 증정해주니 더 좋네요, 두 개 붙어 이 가격). This packaging strategy is a primary purchase driver for cost-conscious consumers.
Visible texture and hydration benefits
Consumers report immediate skin improvements (각질이 오프, 주름 개선) that justify the purchase, especially for those with dry or flaky skin in winter months.
