<p>This study aimed to examine the relationships among individuals’ perceptions of aesthetic procedures on social media, social media addiction, and social desirability, and to investigate how social desirability predicts the other two variables. A cross-sectional study was conducted with 903 participants aged 18–65 living in the city center of Yozgat, Turkey. Data were collected using the Perception of Undergoing Aesthetic Procedures on Social Media Scale, the Social Media Addiction Scale – Adult Form, and the Social Desirability Scale. Descriptive statistics, Pearson correlation, and multiple linear regression analyses were performed. The findings showed that marital status and daily internet usage were significant predictors of social media addiction (<i>p</i> &lt; 0.05). Additionally, internet usage was a significant predictor of social desirability (<i>p</i> = 0.001). Time spent specifically on social media was found to significantly predict perceptions of aesthetic procedures on social media (<i>p</i> = 0.029). The desire to undergo aesthetic procedures was significantly associated with all three measured variables: social media addiction, social desirability, and perceptions of aesthetic procedures. Furthermore, social media addiction and aesthetic perceptions together explained 43.9% of the variance in social desirability. These findings reveal significant relationships between social media use, social desirability tendencies, and perceptions of aesthetic procedures. Future research should consider qualitative and longitudinal approaches to better understand the psychological and social consequences of these interactions.</p>
