<![CDATA[One of the current promotional strategies adopted by many brands in Indonesia is leveraging the K-Wave (Hallyu) phenomenon. A skincare manufacturer aims to capitalize on this opportunity by appointing the popular K-Pop girl group, Twice as their brand ambassador. The significant investment in this collaboration raises high expectations for skincare products, particularly regarding their chosen brand ambassadors' impact on purchasing decisions and brand loyalty. Hence, this research aims to examine the influence of various dimensions (visibility, credibility, attractiveness, and power) of K-Pop artist Twice on skincare product consumers' purchasing decisions and brand loyalty. Furthermore, the study aims to investigate the mediating role of customer satisfaction in the relationship between purchasing decisions and brand loyalty among cosmetics product consumers. This research employs a non-probability purposive sampling technique, with a sample size of 200 respondents aged between 15 and 34 years, encompassing all genders. The respondents must have prior experience using cosmetics products and be aware of Twice as one of the skincare brand ambassadors. The data analysis technique employed is the Structural Equation Modeling (SEM) Partial Least Squares (PLS) method. The findings indicate that the dimensions of "visibility" and "power" have a positive yet insignificant effect on purchasing decisions, while "credibility" and "attractiveness" exhibit a positive and significant impact on purchasing decisions. Additionally, the "visibility" dimension of the brand ambassador demonstrates a positive and significant influence on brand loyalty. However, the dimensions of "credibility," "attractiveness," and "power" of the brand ambassador show a positive but insignificant effect on brand loyalty. Furthermore, the results highlight the positive and significant influence of purchasing decisions on customer satisfaction, and customer satisfaction, in turn, has a positive and significant impact on brand loyalty.]]>
