themselves: they are the key to a successful treatment with an appealing aesthetic outcome. In the field of relaxation with BoNT A, the individualised, customised approach marks the more common requests of patients, although every treatment should be based on a full knowledge of the facial anatomy and respecting the registration trials for this pharmaceutical. But low-dosing for a natural look and customised treatments are the current trend. For dermal filler injections, refining the injection

malplacement, uneveness or overcorrection, resulting in the most natural reshaping and volumising effect using a dermal filler. Furthermore, the reduction of side-effects related to injection techniques, such as redness, swelling, bruising and pain, offers far more comfort to the patient during treatment. The use of automated injection systems to control the delivery, flow and pressure of the material during injection, also marks a step ahead. The application of flexible, blunt- tip cannulae and the combination of the dermal filler material with local anaesthetic in the correct ratios should be part of the armamentarium of the advanced injector. And finally, treatment should focus on the implementation of modern, advanced injection techniques,
such as the 3D vectoring lift. This technique is particularly suitable for augmentation of the mid-face2
