Lookism is discrimination, prejudice, or stereotyping based upon physical appearance, including skin tone, body modification, and/or clothing. It is the notion of considering one’s physical appearance or adhering to specific beauty standards as superior, which often leads to discrimination and negative attitudes toward those who do not meet these criteria. This prejudice takes various forms, such as body shaming and exclusion based on looks, perpetuating harmful stereotypes and undermining individuals’ self-esteem.
