In this video, after identifying the aesthetic facial treatments to be carried out on our patient, we highlight the different arteries that run through the face. The objective is to have a perfect anatomical knowledge of the face in order to inject only in the “safe” areas. We also highlight the “safety triangle” which identifies a non-injection area which, if it were, would have the opposite effect from that sought, namely to raise the cheekbone. Once the arteries and the different areas have been identified, we can safely inject hyaluronic acid into the different entry points of the face: cheekbones, temples, eyebrows, nose, chin.
