Social networks Snapchat and Instagram have a great number of users, and are especially popular among adolescents and young adults. On these social networks, beautifying selfie filters make it possible to beautify the facial appearance. These filters have gained great popularity among women. Therefore, the aim of this research was to examine the effect of time spent on the social networks Snapchat and Instagram and the attitude towards the use of beautifying selfie filters on the attitude towards aesthetic procedures and physical appearance satisfaction. Adolescent girls and young adult women between the ages of 18 and 29 (N = 261) participated in this research. To collect data, the following were used: 1) time spent on Snapchat and Instagram, 2) The Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King and Henderson-King, 2005), 3) Body Appearance (Dis)satisfaction Scale, (BAS-R; Martins, Barra, Silva, Maroco and Campos, 2021) and 4) scale of attitude towards the use of beautifying selfie filters that is created for the purpose of this thesis. Several findings were obtained. First, the results showed that neither physical appearance satisfaction nor attitude towards aesthetic procedures can be predicted based on the time spent on Snapchat and Instagram. Second, the obtained results show that the attitude towards aesthetic procedures can be predicted based on the attitude towards the use of beautifying selfie filters. More precisely, the participants in this research who had a more positive attitude towards the use of beautifying filters were more prone to aesthetic procedures. Third, the attitude towards the use of beautifying selfie filters is a significant predictor of satisfaction with facial appearance, but not in the expected direction. Namely, a more positive attitude towards the use of beautifying filters predicts greater facial appearance satisfaction. Fourth, according to the results obtained in this research, physical appearance satisfaction is not a significant mediator in the relationship between the time spent on Snapchat and Instagram and the attitude towards aesthetic procedures. Fifth, facial appearance satisfaction is a significant mediator in the relationship between the attitude towards the use of beautifying selfie filters and the attitude towards aesthetic procedures, where occured a partial mediation. A more positive attitude towards the use of beautifying filters predicts greater facial appearance satisfaction, which then results in a lower inclination towards aesthetic procedures.
