With the development of technology and social networks, they have become excellent platforms that companies can use to advertise their products. Marketing companies use a sexualized representation of women to attract attention, which often leads to negative consequences, such as sexualization and sexual objectification of the female body. These phenomena have a negative impact on young people, who are the most frequent users of social networks. Therefore, this research wanted to investigate how sociodemographic and psychosocial characteristics, and the use of social networks influence the level of sexualization and the acceptability of ten selected advertisements. Before conducting the central survey, a pilot survey was conducted in which independent evaluators assessed the level of sexualization of ten advertisements, and according to their assessments, the advertisements used in the central survey were categorized. Data were collected using an online questionnaire that was distributed to selected Facebook groups. Based on a sample of 114 participants, of whom 40 male and 74 female participants with an average age of 22.6 years belonged to the age group of 18 to 25 years, we can conclude that, in general, less sexualized advertisements are more acceptable to the participants, and sexual preoccupation stands out as a significant predictor of acceptability of sexualized advertisements. This research can help young people recognize sexualized content on social networks and point out the unacceptability of such content in advertisements.
