Accordingly, various studies have been conducted, but studies analyzing the functions of beauty applications have beeninsufficient. Therefore, this study aims to analyze the functions of beauty applications and help in the development anddevelopment of future beauty applications. The research method analyzed the functions of beauty applications that havebeen downloaded more than 100 million through the Google Play Store, and the search period was from October 11,2020 to November 3, 2020. As a result of the study, it was found that there is a difference in the name of the function,the function being provided, and the application method of the function for each application. As a result of function anal-ysis, a total of 36 functions were classified, and it was analyzed that 30 functions were provided in YCM, 14 functionsin YCP, 21 functions in BP, and 10 functions in SS. Therefore, by analyzing the functions of beauty applications throughthis study, we intend to provide useful data in the future development of beauty applications and help in the developmentof beauty applications.
