title: Botulinum neurotoxins and injectable fillers: minimally invasive management of the aging upper face.
abstract: Attitudes on the use of injectable agents for rejuvenation of the face have changed dramatically over the last decade. This is particularly true for the upper third of the face, where the impact of the use of Botox had its first application. In the author's opinion, no technique, device, or pharmaceutical has had a greater impact on the aesthetic surgery than the now widely used botulinum toxin as an injectable agent.
