Hyaluronidase: what is your fear?

Introduction The aesthetic treatment based on fillers with hyaluronic acid presents an increasing demand in the present day because it is considered a safe and minimally invasive procedure. In the management of adverse effects or more severe complications of hyaluronic acid-based fillers, hyaluronidase is the treatment of choice. Objective To demostrate efficacy in reversibility and safety in the treatment of HA complications. Methods It is a retrospective study article that reports the use of hyaluronidase in the main undesirable effects of fillers in 114 patients in a private dermatological clinic from 2015 to 2018. Results The target of the application was 51 cases of overcorrection (45%), 50 cases of Tyndall efect (44%), and 13 late nodules (11%). When we evaluated the areas where HYAL was injected, we found that the area with the most indication of application of the product was the eyelid region (58 injections). Conclusion This study concluded that HYAL is a safe and effective drug in the management of mild adverse events of HA applications with no severe side effects in our protocol of use.
