title: [Techniques to enhance the accuracy and efficiency of injections of the face in aesthetic medicine].
abstract: The common principle of injections in esthetic medicine is to treat and to prevent the signs of aging with minimal doses and with more precision and efficiency. This relies on functional, histological, ultrasound or electromyographic analysis of the soft tissues and of the mechanisms of facial skin aging (fine lines, wrinkles, hollows). These injections may be done with hyaluronic acid (HA) and botulinum toxin. The aim of this technical note was to present four delivery techniques allowing for more precision and low doses of product. The techniques of "vacuum", "interpores" and "blanching" will be addressed for HA injection and the concept of "Face Recurve" for botulinum toxin injection.
