The face, found on the front of the head in humans and many animals, is crucial for housing vital sense organs like the eyes, nose, and mouth, and plays a key role in expressing emotions. In humans, it's fundamental for identity, recognition, and communication, with distinct features such as the forehead, eyes, nose, cheeks, and mouth. The unique shape of each face is influenced by underlying skull bones and soft tissues, while specialized brain regions, like the fusiform face area (FFA), are dedicated to facial recognition. A highly sensitive part of the body, the human face undergoes continuous changes due to age, genetics, and environmental factors. This inherent variability and the desire for youthfulness have led to the establishment of a vast cosmetics industry focused on altering or maintaining facial appearance.
