Identifying the most "toxic" social media platform is subjective, so we don't have a definite answer to this question. Yet, sites like Instagram or TikTok, which focus on pictures and videos, often show unrealistic ideas of beauty. This might cause body dissatisfaction and low self-esteem, while potentially leading to anxiety and depression.  It's important to remember that social media presents polished versions of life, not reality. Nowadays, with the increased use of AI for image edits, distinguishing truth from fiction becomes unclear. Besides that, this new development may also affect how people perceive reality.
