UNNI: Plastic Surgery & Beauty positions itself as Korea's leading digital platform for cosmetic procedure discovery and booking. The application serves as a comprehensive marketplace connecting patients with over 7.2 million registered users to verified clinics and surgeons specializing in procedures ranging from double eyelid surgery to laser treatments. Developed by Healingpaper Co., Ltd., the platform emphasizes safety and transparency in an industry where reliable information can be challenging to obtain. The application's core functionality revolves around three primary features: clinic discovery through verified reviews and before/after photos, price comparison tools for various procedures, and integrated booking systems. Users can filter clinics by specialization, location, and patient ratings, while the platform's deal section offers discounted packages for specific treatments. The app maintains a database of practitioner credentials and clinic certifications, addressing safety concerns that frequently accompany medical tourism decisions. User experience presents both strengths and challenges based on linguistic capabilities. The interface follows standard Korean app design conventions with clear categorization of procedures and clinics, though the primary language remains Korean throughout. Navigation proves intuitive for Korean speakers, while non-Korean users report varying success rates despite some clinics offering translation services. The booking flow incorporates consultation scheduling and preliminary questionnaires that help match patients with appropriate practitioners. User feedback trends reveal consistent praise for the platform's clinic discovery capabilities alongside language-related limitations. EM MA (October 2020) noted the app's effectiveness despite language barriers, stating 'I was able to find the best clinic for me.' David Yoo (October 2022) highlighted financial benefits: 'Was able to find an amazing deal on Lasek eye surgery.' More recent reviews like Dawn Lim (May 2024) acknowledge improved foreigner support through online consultations. However, multiple reviews from 2019 indicate persistent confusion among non-Korean speakers regarding navigation and feature discovery. The platform demonstrates clear strengths in clinic verification and price transparency within Korea's competitive aesthetics market. Its primary limitation remains language accessibility, as the interface and clinic communications predominantly operate in Korean without comprehensive multilingual support. UNNI proves most effective for Korean-speaking users or medical tourists working with local translators, providing unprecedented access to verified information in a market where international patients frequently face information asymmetry.
