This empirical study examines the impact of digital influencers on the formation of beauty and gender stereotypes, as well as their influence on body satisfaction among social media users. Through an online survey of 628 participants, using validated measurement scales and partial least squares structural equation modeling (PLS-SEM), the research tests multiple hypotheses about the relationships between credibility, trust, identification with influencers, gender stereotype, beauty stereotype, and body satisfaction. The results reveal that influencer credibility is the most robust predictor of trust in the influencer (β = 0.811), establishing a causal sequence where credibility generates trust, which in turn also promotes identification with the influencer. Identification with the influencer significantly influences body satisfaction (β = 0.408) and the formation of beauty (β = 0.293) and gender (β = 0.232) stereotypes. Contrary to expectations, trust in the influencer does not have significant direct effects on stereotypes or body satisfaction but functions as a precursor to identification with the influencer. The study contributes theoretically by clarifying mechanisms of digital influence and alerting to ethical implications related to the perpetuation of unrealistic beauty standards through social media.
