Seoul Sister

Seoul Sister is an AI-powered K-beauty advisor built around Yuri, a virtual skincare consultant that lives in your browser. You can talk to her for free without signing up — she'll ask about your skin type, budget, and concerns, then recommend real products with specific prices. Point your camera at a Korean label and she translates it, scores the ingredients, and checks if it's fake. She also tracks your progress over time with a Glass Skin Score based on photos you snap.

The system runs on six specialist AI agents working under Yuri: an ingredient analyst that decodes INCI lists, a routine architect that spots conflicts between products, an authenticity investigator that checks batch codes and packaging, a trend scout pulling live Olive Young bestseller data from Korea, a budget optimizer that finds ingredient-matched dupes, and a sensitivity guardian that flags potential irritants. Yuri remembers everything across sessions, so recommendations get sharper as she learns your skin history and preferences.

This tool is for anyone who wants real Korean skincare intelligence without the hype. Beginners get a simple starting routine without the 10-step pressure. Ingredient nerds can search 5,900+ products by specific ingredients or filters like fragrance-free. The counterfeit detection and price comparison across US and Korean retailers make it practical for shoppers. It's a guide that actually knows your skin, not a generic quiz.
