But what exactly is a complication? In Aesthetic Medicine we talk about complication when we are faced with an adverse event that is not expected: it is something that happens by virtue of either the biological reaction by the patient or a technical error performed by the operator. The vast majority of complications is always operator-dependent ie is a technical and "choral" error of planning, product choice, depth level, injection zone target, amount of product injected, maneuvers that are taken, Therefore, the focus on this issue aims to emphasize what are the aspects that must always be taken into account in order not to run into possible complications.

Sometimes the "complication n.1" are unrealistic expectations of patients. Therefore, correct doctor-patient communication is essential: the doctor must always be very clear and transparent in communicating both the benefits but also the possible complications according to the patients' wishes. If, in fact, we find this fundamental misunderstanding at the base, we arrive at the consequential distrust that feeds in the patient that towards the professional and in general towards that of aesthetic medicine.
