There are many intricate anatomical differences between men and women. These changes are seen in both skeletal and muscular aspects and are translated clinically in the areas of focus during augmentation. A man’s skeleton is larger, its surfaces rougher, and the edges are more angular in nature. A woman’s skeleton has a more pronounced zygoma and zygomatic arch . A man’s muscles are also thicker compared to a woman’s, which accounts for the skeleton’s rougher surface. If the face is divided into thirds, an upper, middle, and third, these will be highlighted accordingly.

The upper third consists of the forehead , which includes the glabellar complex and eyebrows as well as the temples . Though augmentation is not commonly performed in the forehead of men, fillers are more readily injected in women owing to the apparent decrease in volume in that gender. For the eyebrows care should be taken as augmentation in women is made by injecting the area above the eyebrow . This causes a lift of the eyebrows that is considered attractive. For men, that look may be feminizing and thus injection should be performed lower on the eyebrow to enhance the skeletal prominence. The glabella and the temples for both sexes are injected in the same fashion.
