The purpose of this study was to explore the effects of social media on self-perception and personality development of high school students, with an added focus on the positive correlation between social media usage and self-perception. While there are limitations to the data collection process, the analysis suggests that increased social media use is associated with increased pressure to adhere to appearance standards. High school students' self-evaluation of their own appearance, attention to peers' appearance, and media interactions with peers all contributed to changes in perception and personality. Understanding these dynamics is critical for educators, parents, and researchers when it comes to the impact of social media on adolescent development. Future studies should establish a target number for data collection to ensure more robust findings. This study provides insight into the complex relationship between social media, self-perception, and personality development among high school students.
