Book excerpt: With the ever-increasing popularity of injectable toxins and fillers, all clinical practitioners in minimally invasive aesthetic procedures need to be experts in the anatomy of the face. This is a detailed and informative guide from international experts to all aspects of the facial anatomy of the presenting clinical patient - how it changes with age, how it differs in different patients, how it is layered, and what danger zones it may contain. An integral ebook contains videos demonstrating how injection can best be accomplished in each of the anatomical areas considered.
