INTRODUCTION
Botulinum toxin (BoNT) injections are commonly used to improve facial aesthetics by smoothing hyperdynamic rhytides of the face and neck. In recent years, the use of BoNT has evolved to reflect a more three-dimensional approach to facial rejuvenation, often in combination with soft-tissue augmentation or other restorative procedures. Moreover, a better understanding of its mechanism of action has led to innovative indications across a number of therapeutic fields.
