Masao facial makeup, a unique folk cultural form from the Baoji region, carries a rich traditional heritage. However, its inheritance and development have long been hindered by limited dissemination channels and insufficient public attention. This paper proposes an innovative model for deeply integrating Masao facial makeup with computer software, and transforming it into an interactive filter within social media applications. This unique design not only fills the gap in the digital representation of Masao facial makeup but also takes a crucial step in combining folk culture with modern technology. Through a systematic survey, this paper comprehensively collects and precisely analyzes user expectations for functionality and suggestions for improvements regarding the Masao Facial Makeup APP. Based on this, the paper develops a functional system that aligns with user needs. The art essence of Masao facial makeup is then cleverly incorporated into the app's innovative interface design. A group of 50 representative volunteers are selected to undergo a strict feasibility test of the app, and the APP is then compared to two mainstream traditional cultural apps on the market. The results show that the Masao Facial Makeup APP demonstrates significant advantages. This APP far surpasses the control group in core dimensions such as visual effects, functional attributes, interactive experience, and operational experience, with scores of 4.2, 4.9, 4.5, and 4.6, respectively. During the testing process, volunteers highly praise the app's interactive interface design and fully recognize the smoothness and convenience of its operation. The key research contribution lies in successfully establishing a new paradigm for the cultural inheritance of Masao facial makeup. By leveraging digital tools, it significantly enhances its dissemination effectiveness and cultural influence, providing an innovative template and practical path for the protection and inheritance of similar folk cultures. This paper strongly promotes the innovative development and sustainable inheritance of folk culture in the digital age and holds the potential to revitalize more cultural treasures with the support of modern technology. It enriches the cultural inheritance ecosystem, and expands the boundaries and possibilities of cultural transmission.
