Impacts of facial filters on Instagram: self-image, digital vulnerability, and aesthetic standards in Brazil
摘要
This study investigated the associations between Instagram facial filter usage, visual self-presentation behaviors, and body image perception among Brazilian users. Drawing on a sociotechnical approach, digital vulnerability is defined here as both a relational and measurable construct, reflecting individuals’ susceptibility to internalizing aesthetic ideals promoted and amplified by platform-specific features. Four cross-sectional studies were conducted with a sample of 409 participants (aged 18–65), using psychometric instruments to assess digital behaviors, self-image, and acceptance of aesthetic procedures. In Study 1, appearance-based comparisons were positively correlated with body dissatisfaction (ρ = 0.742, p < .001 for men; ρ = 0.726, p = .001 for women), as well as with filter use (ρ = 0.282, p < .01). In Study 2, gender-differentiated correlations emerged between filter use and intention to undergo aesthetic procedures (ρ = −0.262, p = .011 for men; ρ = 0.246, p < .001 for women), and between selfie-sharing frequency and surgical intent (ρ = 0.209, p < .001). In Study 3, time spent on Instagram was positively associated with acceptance of aesthetic procedures (ρ = 0.270, p = .008 for men; ρ = 0.306, p < .001 for women), and a Mann-Whitney U test indicated greater predisposition among men (U = 11164.000, p < .001). In Study 4, a structural path model using PLS-SEM was tested, revealing that time spend on Instagram, filter use, and appearance comparisons significantly predicted surgical intention (R² = 0.17). The correlations identified support the conceptualization of digital vulnerability as a construct shaped by visual engagement practices and normative aesthetic exposure on Instagram.
