Introduction: Aesthetic medicine represents an emerging field for many specialties. Nowadays, a plethora of approaches are available to rejuvenate the human body and face, the latter being a frequent target for the placement of filling substances to correct wrinkles and volume loss.

Expert opinion: A profound knowledge of the facial anatomy as well as extensive experience with the various filling techniques and suitable materials for the respective areas remains crucial to prevent adverse events associated with filling procedures to the human face. Since side effects such as malar edema and foreign body granuloma do affect patients physically and psychologically to a significant extent and their successful treatment still remains challenging, further in depth studies on the tolerability of many filling materials utilized are required.
