Facial features refer to the distinct characteristics of a person's face, including the eyes, nose, mouth, and ears. These features contribute to an individual's unique appearance and can vary widely among different people. For example, the shape of the nose can be straight, curved, or flat, while eyes can differ in color, size, and shape. Facial features also play a significant role in non-verbal communication. Expressions formed by the mouth and eyes can convey emotions such as happiness, sadness, or surprise. Additionally, the arrangement and prominence of these features can influence perceptions of attractiveness and identity in various cultures.
