  • Publication number: 20250046462
    Abstract: An information processing system provides information regarding a product for skin and can include a control unit or controller. The control unit analyzes biological information regarding skin of multiple users and generates multiple skin classifications for classifying the skin of the users based on analysis. The control unit stores user identification information for identifying a user of a source of the biological information in association with one of the generated skin classifications and stores product information regarding multiple products relating to skin in association with the corresponding skin classification. The control unit receives, from a terminal of a user corresponding to the user identification information, a search request for product information using the skin classification as a search criterion.
