Upper third of the face: boundaries and areas

In the classic facial analysis, the face seen from the front is divided into three horizontal bands. The upper third runs from the hairline (trichion) to the glabella, at the level between the eyebrows. It includes the forehead, the glabella, the eyebrows and, laterally, the temples.

In a face considered proportional, the three thirds have similar heights. Comparing them is one of the first steps of the facial assessment by thirds, but it is a reference and not a rule: ethnicity, sex, age and the hairline (which changes with baldness) all alter the reading.

What is usually treated in the upper third?

The most frequent concerns are the dynamic lines of the forehead and glabella, generally treated with botulinum toxin, and hollowing of the temples, which can be addressed with filler. The position and shape of the eyebrows also enter the assessment, because they are strongly influenced by the muscles of the area.

What precautions apply?

The glabella and the temples are among the areas of highest vascular risk for dermal fillers. With toxin, a poorly adjusted dose or point can cause drooping of the eyebrow or the eyelid. Indication, product and dose are defined by the licensed professional, after assessment.
