1. Introduction

Social media is now an indispensable part of daily life for people across the globe. By 2024, there will be over 4.9 billion social media users worldwide, particularly on Instagram, TikTok, and Snapchat, which have all expanded their reach, particularly with young women aged 16 to 30 years old [1]. Although content on these sites is now some of the most visually-driven in our culture, the saturation of idealized images on social media is an environment that can affect users’ self-concept and body image; this can lead to appearance anxiety—a state of chronic worry or dissatisfaction about the way one looks [2].

Appearance anxiety is related to multiple mental health concerns, including depression, low self-esteem, and eating disorders [3]. It is the culmination of a culturally rich fascination with women's beauty and perfection, a desire influenced by the countless hours young women spend scrolling through social media where visual content is now even quicker and more prevalent to experience and be compared to. This manuscript will investigate how social media exacerbates women's appearance anxiety, focusing on the impact of social media's visual nature, algorithms, and social validation, using literature review and selected case studies to investigate the social and psychological dimensions of appearance anxiety in women's health and provide informed recommendations to lessen its effects. The significance of this research lies in its potential to raise awareness about the mental health challenges associated with social media use, offering valuable insights for policymakers, educators, and future researchers who aim to develop interventions that promote healthier digital environments.

2. Development of modern social media

Modern social media platforms have evolved at a remarkably even faster pace over the past decade. Early platforms like Facebook and Twitter started out as mainly text-based interactions, but mobile smart devices equipped with high-resolution cameras changed where user behavior shifted from sharing text to sharing images and standard videos. Instagram was launched in 2010 with a key aspect being to provide mobile-device users with simple photo filters and a straightforward mobile interface, which took off and became a major visual hub for beauty, fashion, and lifestyle content [4]. TikTok, launched in 2016, was a game-changing platform in how visual content can be shared through short-form videos, capitalizing on creative and viral visual productions surrounding themes of appearances and transformations.

Technological enhancements including augmented reality (AR) filters, beauty apps, and AI-driven image processing allow for even more alterations and possibilities of these idealized versions users present to the world [5]. Algorithms present on these sites provide users a feed of content from individuals who attract engagement - normally conventionally attractive people or visual effects - to subscribers, creating echo chambers of narrow beauty ideals [6]. Additionally, the global reach of social media platforms contributes to a globalization of beauty standards that often privilege Eurocentric and youth-centric content across countless cultural differences [7].

Statistics show, rather unequivocally, that social media platforms have grown in excess of this transformation with Instagram having over +2 billion monthly active users with 70% aged under 35, and TikTok surpassing 1 billion active users globally, primarily Gen Z and Millennials [8]. Having such a large population of young individual users on content dedicated to appearance, predominantly women, means there is a profound role in reinforcing social norms of looks for social media platforms.

3. The impact of social media on women’s appearance anxiety

3.1. Influence of visual content and algorithms on body image insecurity

Social media platforms bombard users with visual content that is clearly unrealistic and idealized in nature. Research studies have consistently demonstrated that when women view such content, body dissatisfaction and appearance anxiety increase [9]. Algorithms react to engagement and prioritize, so if users post something that garners a lot of likes, the algorithm will continuously display similar posts, normalizing certain aesthetic ideals [10]. Users may take for granted the idea that certain things are normal or to be expected, leaving them to a constantly critical evaluation of self.

Neuroscience suggests that viewing idealized visual images similar to what is on social media activates brain regions that are associated with reward and social cognition, reinforcing desires toward conformity and validation [11]. With a social premise and algorithm, a heightened sense of pressure surrounds conforming to societal expectations, ultimately increasing self-consciousness and contributing to maladaptive behaviours like excessive dieting or modifying the self with cosmetic surgery or alteration [12].

3.2. Case studies illustrating the effects of social media on appearance anxiety

A salient example is the "Instagram Face" phenomenon, a term adopted by cosmetic surgeons to define a homogeneous facial presentation promoted by influencers characterized by smooth and contoured skin, large eyes, high cheekbones, and plump or full lips [13]. Patients often come in with digitally manipulated selfies presented as templates from which they want their surgery to be based, reflecting the strong propensity for visual images seen online to compel body modification trends [14].

TikTok’s “Glow Up” challenges provide another example of producing videos with visual change, where users signal the beginning with an extreme “before” and the extreme transformation glance. While these videos can provide confidence improvement for individuals who feel extreme change is possible, they also perpetuate the notion that our natural looks are not enough, thus perpetuating appearance dissatisfaction [15]. Several users note they felt pressured into unhealthy behaviors to produce these changes, illustrating the conflicted impact of social media trends on body image [15].

4. Factors contributing to intensification of appearance anxiety

4.1. Increased exposure to idealized images

Unlike traditional media, which typically dictates a structured release of content (e.g., set hours of entertainment), social media provides a continuous and personalized feed of images and videos. This continuous exposure to an unrealistically curated form of beauty provides negligible opportunity for critical reflection and allows for a more implicit acceptance of unrealistic forms of beauty [16]. Psychological theories on the way individuals evaluate themselves based on others' appearances include social comparison theory, which entails how often individuals evaluate themselves by comparing themselves to others, resulting in feelings of societal inadequacy when making those comparisons to idealized or curated images [17]. Additionally, cognitive biases such as confirmation bias (a tendency to search for, interpret, favor, and recall information in a way that confirms one's prior beliefs or hypotheses) and attentional bias (the tendency to focus one's attention too much on style and appearance related content) continue identify and reinforce focusing on appearance-related content; increasing involvement and continuation of engagement with unrealistic standards of beauty [18]. Similarly, research indicates that social media can foster increased body surveillance and increased internalization of both the idealized beautification of peers and other social media influences. Both body surveillance and internalization of beauty ideals were some of the most significant indicators of later appearance anxiety [19].

4.2. Peer comparison and validation culture

Social media relies heavily on measurable results—likes, comments, shares—that creates a culture for society that measures validation externally. Women often compare themselves not just to celebrities but to their peers belonging to the same age or social group, which can make these comparisons more personally salient [20]. This peer comparison can exacerbate feelings of not being good enough, especially when users feel that their content is less liked or attractive compared to those they are using as a reference.

The need for validation can create a cycle of self-objectification, where women see themselves first and foremost as an object for others’ appraisal, which can lead to increased body shame and anxiety [21]. Furthermore, studies suggest that social media increases intrasexual competition among women, resulting in increased threat related to appearance as users compete for social recognition and desirability [22].

5. Coping mechanisms and potential solutions

5.1. Media literacy and digital self-awareness

Enhancing media literacy is a valuable way to combat the negative influence of social media on appearance-related anxiety. Programs that educate social media users to critically engage with images online, identify digital manipulations, and situate content in algorithmic biases have been shown to mitigate the impact of unrealistic beauty ideals on participants' lives [23]. Encouraging individuals to foster a digital self-awareness fosters healthy judgments about social media content and a level of critical engagement that fosters resilience to negative social comparisons.

Media literacy programming is becoming a part of school and community organization curricula, with an emphasis on highlighting diverse and inclusive representations of beauty that support a positive body image [24].

5.2. Policy and platform regulation

Countries around the world have started to implement policy interventions to tackle the concerns presented by social media. Some jurisdictions have required influencers to disclose if they have used beauty filters or digital alterations in their sponsored posts to increase transparency [25]. Platforms themselves have also taken actions, such as restricting the use of beauty filters or instead curating content that promotes body diversity and mental health awareness [26].

Further regulatory measures could mandate algorithmic transparency and the promotion of diverse body types, ethnicities, and age groups to counterbalance homogenized beauty norms [27]. Collaborative efforts between policymakers, platforms, and advocacy groups are essential to create safer and more inclusive digital environments.

6. Conclusion

This paper has examined how modern social media influences women’s appearance anxiety, highlighting the roles of visual content, algorithmic reinforcement, and social validation cultures. The continuous exposure to idealized beauty standards on platforms like Instagram and TikTok fosters increased self-consciousness and body dissatisfaction, contributing to significant psychological distress. While social media offers unique opportunities for connection and self-expression, its current design often prioritizes narrow aesthetic ideals that can harm users’ mental health. Limitations of this study include its reliance on secondary literature and case examples without primary quantitative data. Future research should focus on longitudinal and cross-cultural studies to better understand the evolving impacts of social media on diverse populations.
