This paper provides an overview of research on social media and body image. Correlational studies consistently show that social media usage (particularly Facebook) is associated with body image concerns among young women and men, and longitudinal studies suggest that this association may strengthen over time. Furthermore, appearance comparisons play a role in the relationship between social media and body image. Experimental studies, however, suggest that brief exposure to one's own Facebook account does not negatively impact young women's appearance concerns. Further longitudinal and experimental research is needed to determine which aspects of social media are most detrimental to people's body image concerns. Research is also needed on more diverse samples as well as other social media platforms (e.g., Instagram).
