Deriving User Experience Insights in Digital Healthcare Beauty Tech Services : Focusing on Skin Diagnosis and Management Functions in Beauty Tech Services

This study presents the concept and methodology of service design through a literature review and analyzes the types and functions of existing beauty tech products to establish a foundation for empirical research. The empirical study applies a macro-environmental analysis methodology to examine industry trends, particularly in the IT, cosmetics, and medical fields, providing a basis for in-depth interviews and deriving key insights. Additionally, in-depth interviews were conducted with 20 men and women in their 20s and 30s, followed by a focus group discussion using the Double Diamond model of service design to extract user experience insights. The study identified three key insights—motivation, personalization, and community— which were used to propose additional functions for beauty tech services. By integrating these insights, this research suggests user-centered design strategies that enhance engagement and satisfaction in beauty tech solutions. Ultimately, this study aims to provide a direction for the development of innovative beauty tech products, fostering cross-industry collaboration and contributing to the sustainable advancement of beauty tech services.
