Using a quantitative approach with Structural Equation Modeling–Partial Least Squares (SEM-PLS), data were collected from 250 respondents through an online survey. The results show that influencer trustworthiness and expertise significantly influence brand image and purchase intention, whereas attractiveness affects purchase intention only through brand image. Informative and interactive social media content positively impacts brand image and purchase intention, whereas entertainment-oriented content does not show a significant effect.

These findings highlight the importance of credibility-driven influencers and informative, interactive content strategies in enhancing consumer purchase intention in the cosmetic industry.]]>
