So-Young International operates as an online platform connecting consumers and medical service providers in China's medical aesthetics market, offering information, provider directories, service reservations, and user-generated content about aesthetic treatments. The company generates revenue through fees charged to aesthetic practitioners for user referrals and reservations, as well as through direct provision of aesthetic services via branded treatment centers and sales of medical equipment and cosmetic injectables acquired through subsidiary operations. The platform serves both individual consumers seeking aesthetic information and access, and medical aesthetic providers—including practitioners, hospitals, and clinics—seeking market visibility and patient acquisition.
