This study aims to determine the effect of two forms of consumer participation, namely consumer-consumer interaction and consumer-brand interaction on consumer brand engagement (cognitive engagement, emotional engagement, and behavioral engagement). As well as the mediating effect of consumer satisfaction in encouraging the influence of consumer brand engagement on brand loyalty (positive eWOM, ongoing search behavior, and repurchase intention) in the context of Indonesian local beauty brands. This study uses a survey distributed online to 328 respondents aged 18-34 years who had purchased and opened the social media of a local beauty brand. The data collected was then processed using the structural equation modeling (SEM) method. The results of this study indicate that consumer-consumer interactions and consumer-brand interactions have a positive effect on cognitive engagement, emotional engagement, and behavioral engagement. It can be seen that consumer satisfaction mediates the effect of cognitive engagement, emotional engagement, and behavioral engagement on positive eWOM, ongoing search behavior, and repurchase intention. This study also provides meaningful implications for marketers to manage consumer participation on social media.
