Leading with the chin: facial rejuvenation of the lower third

02 April 2024
Volume 13 · Issue 3

Abstract

The facial lower third and chin contribute significantly to overall facial balance. Beginning with an anatomical exploration, this article defines the chin's unique features and the evolutionary significance of its projection in humans. The often-overlooked senescent changes of the chin are discussed, as well as congenital contour and projection defects. A sequential treatment model is offered to manage these inherent and acquired lower-third deformities.

This article provides an overview of injectable rejuvenation of the facial lower third, specifically the chin. After defining the chin, we will discuss its uniqueness in humans, sexual dimorphism, manifestations of aging, and finally how to stage injectable treatment to optimise aesthetic outcomes.

Facial injectable treatment, like any other endeavor, begins with the end in mind. Unlike purely therapeutic treatments, aesthetic procedures have to satisfy both the practitioner and the patient.

As obvious as these considerations may seem, treatment results that miss the mark are often the consequence of not thinking through the goals of the patient, and the intentions of the practitioner before the first needle is uncapped. This means that success is often doomed from the start.

In all areas of the face, practitioners need to have a clear and uniform vision of what the ‘optimum’ result looks like. It sounds straightforward until you realise that ‘optimum’ is predicated on and modified by age and gender.
