Beauty standards refer to the societal norms and ideals that define what is considered attractive or beautiful in a particular culture or time period. These standards can vary widely across different cultures and can change over time, influenced by factors such as media, fashion, and historical events. Often, beauty standards emphasize certain physical traits, such as body shape, skin tone, and facial features. For example, in some cultures, slimness is prized, while in others, curviness may be celebrated. These standards can impact individuals' self-esteem and body image, leading to both positive and negative effects on mental health.
