How many equal sections is the horizontal diameter of the face divided into?

The horizontal diameter of the face is divided into three equal sections, which is crucial for understanding facial proportions in esthetics. This division aids in the analysis and design of facial treatments, ensuring balanced aesthetics and effective techniques. These sections typically encompass the forehead, the middle area of the face (where features like the nose and lips are located), and the lower part of the face, including the chin.

Recognizing these divisions allows estheticians to assess facial symmetry and apply their skills in makeup application, skincare treatments, and assessments more accurately. This knowledge helps in creating visually pleasing results that align with the principles of design in esthetics.
