In this study, core technologies applied to the beauty industry (hair, makeup, skin care, nail) in the era of the 4th industrial revolution and the transition of industrial paradigm of literature review was performed. Based on this, analysis and prediction of future trends were performed through case analysis of ICT convergence applied to the beauty industry. As a result, it could be confirmed that these core technologies are progressing in the direction of improving the value of the services provided in the past through convergence. Therefore, it was possible to confirm through case analysis that the direction of the beauty industry was changing from the existing functionoriented professional service concept to customer-centered personalization, prediction, prevention, and participation. This study expands the scope of research on convergence with core technologies of the 4th industrial revolution at the conventional corporate level and expands it to the beauty industry to analyze the future through convergence with core technologies from the beauty business perspective. There are implications for predicting the direction of In addition, by categorizing the beauty industry into four types (hair, makeup, skin care, and nail), specific future directions for each sub-area are presented, thereby presenting practical implications that can be immediately applied to the workplace.
