title: [Frontal muscular balance and botulinum toxin].
abstract: A good knowledge of the anatomy of the muscles of upper third of the face and their function, a good understanding of the famous Frontal Muscular Balance, to consider the anatomic and histological modifications induced by ageing in the cutaneous layer and the muscular function of the underlying "peaucier muscles", are essential for a better approach and for an easy and safe use of botulinum toxin, remarkable product, and for avoiding its operator-dependent risks.
