As interest in health and appearance increases in modern society, the importance of skin care rooms that provide skin care services is also increasing, and the job performance capabilities and job satisfaction of workers working here are closely linked to the quality of customer service. This study aims to empirically analyze how the work environment of skin care room workers affects self-efficacy and work commitment. In particular, by examining whether self-efficacy plays a mediating role in the relationship between work environment and work commitment, the psychological motivation mechanism of skin care room workers is to be identified. This study is a study on the mediating effect of self-efficacy in the relationship between the work environment and work commitment of skin care office workers, and the results of a survey of a total of 160 people using mobile devices are as follows. First, a simple regression analysis was conducted to find out the effect of the job environment on self-efficacy, and it was found that it had a significant effect on self-efficacy. Second, as a result of conducting a simple regression analysis to find out the effect of the work environment on work engagement, it was found that the work environment had a statistically significant effect on work engagement. Third, as a result of conducting a simple regression analysis to find out the effect of self-efficacy on work engagement, it was found that selfefficacy had a statistically significant effect on work engagement. Fourth, as a result of analyzing the mediating effect of self-efficacy in the relationship between the job environment and job commitment, the job environment, an independent variable in step 1, was found to have a statistically significant effect on the parameter, self-efficacy, and the parameter conditions were satisfied. In step 2, the independent variable, the job environment, was found to have a statistically significant effect on the dependent variables, job attachment, job satisfaction, and job responsibility, and the parameter, self-efficacy, were both found to have a significant effect on the dependent variables, job attachment, job satisfaction, and job responsibility. As the parameter, self-efficacy, was added, the effect of the job environment on job attachment, job satisfaction, and job responsibility decreased compared to step 2, indicating that self-efficacy partially mediated the relationship between job environment and job attachment, job satisfaction, and job responsibility.
