Social networks are online platforms that offer users the opportunity to establish new and maintain old interpersonal relationships or contacts. Thus, their use can almost completely change our interpersonal relationships, way of earning, or even our mental health. In my dissertation I present the dangers of social networks and their impact on young people. The aim of the empirical research was to analyze the strategies of self-presentation of Slovenian youth on social networks and then assess the extent to which they are aware of the dangers, such as online harassment, hidden content, negative impact on self-esteem, etc. In the theoretical part, I presented the emergence of the most popular social platforms and their challenges, dangers,
goals and functions. I also devoted myself to comparing the beauty standard on the three most popular networks – TikTok, Instagram and Facebook. I did the empirical part with the help of an anonymous survey, which I shared on my Instagram profile and later analyzed. The questions were mainly related to the way of using social networks and the well-being of the respondents when using them. The results showed that young people are most involved in the Instagram platform, on which beauty standards are given great importance. The results of the survey showed that many of the respondents face a social comparison that can lead to both negative and positive consequences.
