We built a KakaoTalk-native AI beauty shopping assistant over 8 weeks — handling Korean and international beauty consultation, routine building, and conversational commerce. (1) K-beauty routine AI: skin assessment — conversational skin analysis in under 2 minutes covering 피부 타입 (skin type: 지성/건성/복합/민감 — oily/dry/combination/sensitive), 피부 고민 (concerns: 주름/잡티/모공/여드름/건조 — wrinkles/dark spots/pores/acne/dryness), current routine, and ingredient sensitivities. Routine building: personalised Korean skincare routine — 클렌저 (cleanser) → 토너 (toner) → 에센스 (essence) → 세럼 (serum) → 크림 (cream) → 선크림 (sunscreen), with specific product recommendations from 85,000 SKUs optimised for the customer's profile, budget, and brand preferences. Product knowledge: AI trained on full product database including ingredient lists (INCI), product reviews, beauty advisor notes, and brand-specific formulation knowledge — understanding that "이 세럼에 나이아신아마이드가 몇 퍼센트인가요?" (what percentage of niacinamide is in this serum?) requires specific factual answers, not generic responses.
(2) KakaoTalk-native commerce: conversational shopping within KakaoTalk — product browsing through carousel messages, adding to cart through quick reply buttons, and checkout through KakaoPay integration. Routine as cart: when AI builds a skincare routine, all recommended products added to KakaoTalk cart with one tap — "이 루틴 전체 장바구니에 담기" (add entire routine to cart). Rich media: product images, video reviews, and ingredient close-ups shared within KakaoTalk conversation — mobile-optimised visual shopping. Reorder: "지난달에 산 토너 다시 주문해줘" (reorder the toner I bought last month) processed through KakaoTalk with KakaoPay instant payment. (3) Multilingual beauty: Japanese: full Japanese beauty consultation — understanding Japanese skincare vocabulary (美白/bihaku for brightening, 毛穴/keana for pores), Japanese skin concern descriptions, and J-beauty versus K-beauty routine differences. Chinese: Simplified Chinese consultation — understanding Chinese beauty terminology and preferences, addressing the significant Chinese K-beauty market.
English: international English consultation for US, Southeast Asian, and European customers — translating K-beauty concepts and product benefits for Western skincare understanding. Each language with culturally appropriate beauty communication, not just translation. (4) Trend intelligence: real-time trend integration — AI monitoring Korean beauty trends from Hwahae, Naver Beauty, and social media, incorporating trending products and ingredients into recommendations within 24 hours of trending. New product integration: 800+ monthly new product SKUs integrated into AI knowledge base within 48 hours of platform listing — AI always current on latest products. Review synthesis: AI summarising platform reviews by skin type and concern — "이 제품은 지성 피부 리뷰어 중 89%가 모공 축소 효과를 느꼈어요" (89% of oily skin reviewers felt pore-minimising effect from this product).
Trend explanation: when customers ask about trending ingredients or products, AI providing educated context rather than just listing products — explaining why centella asiatica is trending and whether it's suitable for their skin type. (5) PIPA compliance: consent for skin profile — PIPA-compliant consent before storing skin assessment data, with clear purpose limitation (product recommendation only). Photo analysis: any skin photos processed transiently, not stored. Cross-border: international customer data handled per PIPA cross-border transfer requirements. Review data: anonymised review analysis compliant with PIPA personal information principles.
