The issue of social networks in the 21st century is one of the new challenges today's society has to face. Their impact has recently been in tensified and it is assumed that their influence will become even more important in the future. Through social networks users are given the opportunity to create a new virtual self that can differ from their identity and appearance in real life. Young women are frequent users of social media and are exposed to cases where many influential women do not present a realistic picture of themselves. The aim of this study was to present how social media content affects the formation of self-confidence, self-image and perception of physical appearance as well as the attitudes young women have towards that. For the purpose of this study three semi-structured in-depth interviews were conducted with the Generation X, Y and Z respondents. The results of this study showed that there is a difference in the perception of the influence of social networks between the Generation X,Y and Z respondents. The results also showed how the influence of social networks can have an effect on the self-confidence of the respondents.
