Adverse effect of soft tissue augmentation with hyaluronic acid

Cutaneous fillers have been employed in the treatment of wrinkles and scars. The high biocompatibility and rare adverse effects described in the literature represent advantages of hyaluronic acid (HA) compared to other fillers. We report the case of a patient submitted to soft tissue augmentation with HA (Restylane) for the treatment of wrinkles on the lower third of the face who presented a foreign-body type granulomatous reaction which revised the literature.
