Introduction: In the last decade, the use of hyaluronic acid fillers for facial enhancement has increased in Latin America. Hyaluronic acid fillers are considered relatively safe with a low incidence of adverse events. Because adverse events are not seen frequently in clinical practice or have been potentially underreported, there is a need for more guidance on the diagnosis and treatment of Hyaluronic acid-related adverse events. Objective: To provide an enhanced understanding of hyaluronic acid-related adverse events and to propose recommendations for their diagnosis and treatment. Methods: A 25-member multi-disciplinary expert panel meeting of Latin-American physicians was convened in Sao Paulo, Brazil to discuss what is known about hyaluronic acid-related adverse events and to provide insights based on clinical experience. Recommendations and algorithms were developed through a consensus process. Results: The panel categorized hyaluronic acid-related adverse events based on 3 time frames of onset (immediate, early and Late) and proposed a new term for adverse events that display persistent, intermittent, delayed Swelling (PIDS). Algorithms were created for diagnosis and treatment for each time frame. Conclusions: The new consensus algorithms for time-related diagnosis and treatment of hyaluronic acid-related adverse events will provide guidance for best practices in the clinical use of hyaluronic acid fillers.
