An increased understanding of the volumetric changes that occur with aging and their effect on our perception of beauty has changed the way we use fillers over the last decade. Rather than filling individual wrinkles, modern soft-tissue augmentation focuses on replenishing lost fat pads, providing increased structural support and volume, and constructing facial contours. Injections may be done by bolus to lift or by fanning along vectors. In recent years, the availability of new tools has introduced still more possibilities for variation in the injection procedure. Although manufacturers may claim improved cosmetic results and fewer complications, is it the product being injected, the tool used to inject, the injection technique, the injector or a combination that is responsible? Herein, we describe injection techniques with and without the use of blunt-tipped microcannulas for facial contouring, and we outline when and where their use can provide a less traumatic, reliable, and versatile technical option for the treatment of facial aging.
