What is the Upper Third of the Face?
The upper third of the face is an anatomical region that comprises the forehead, eyebrows, eyes and the region around the eyes, known as the periocular region. This region is of extreme aesthetic and functional importance, as it is responsible for transmitting facial expressions, protecting the eyes and housing vital structures, such as the muscles responsible for moving the eyelids and the lacrimal glands.
Anatomy of the Upper Third of the Face
The upper third of the face is made up of several anatomical structures, which perform specific functions and contribute to facial harmony. Among the main structures present in this region, the following stand out:
Forehead
The forehead is the upper portion of the face, located between the eyebrows and the hairline. It is a flat and smooth region, covered by skin and muscles. The forehead is responsible for protecting the brain and houses the frontal muscle, responsible for raising the eyebrows and forming horizontal wrinkles in the region.
Eyebrows
The eyebrows are hairy structures located above the eyes, which have the function of protecting the eyes against sweat, dust and other external agents. Furthermore, eyebrows also play an important role in facial expression, conveying emotions and contributing to the aesthetic harmony of the face.
Eyes
The eyes are sensory organs responsible for vision. They are made up of several structures, such as the cornea, iris, pupil, retina and optic nerve. In addition to their visual function, the eyes also play a fundamental role in facial expression, conveying emotions and communicating with the surrounding environment.
Periocular Region
The periocular region is the area around the eyes, which includes the eyelids, eyebrows, and wrinkles around the eyes. This region is of extreme aesthetic importance, as it contributes to facial expression and the overall appearance of the face. Furthermore, the periocular region also houses vital structures, such as the lacrimal glands, responsible for producing tears.
Functions of the Upper Third of the Face
The upper third of the face performs several functions, which go beyond aesthetics. Among the main functions of this region, the following stand out:
Facial expression
The upper third of the face is responsible for transmitting facial expressions, such as surprise, joy, sadness and anger. These expressions are formed by the movement of the muscles in the forehead, eyebrows and eyelids, which are controlled by the nervous system.
Eye Protection
The upper third of the face plays an important role in protecting the eyes against external agents such as sweat, dust, insects and intense light. Eyebrows and eyelids help prevent these agents from entering the eyes, keeping them clean and healthy.
Facial Aesthetics
The upper third of the face also contributes to facial aesthetics, as it is an area that attracts a lot of attention. Well-defined eyebrows, expressive eyes and a smooth, wrinkle-free forehead are aesthetically desired characteristics, which can be achieved through aesthetic procedures and specific care.
Conclusion
The upper third of the face is an anatomical region of extreme aesthetic and functional importance. Understanding the anatomy and functions of this region is essential for healthcare professionals, such as doctors, plastic surgeons and dermatologists, who work to correct imperfections and facial rejuvenation. Furthermore, knowing the upper third of the face is also relevant for people interested in aesthetic care and maintaining a harmonious and healthy facial appearance.
