Yes, hyaluronic acid is considered one of the safest filler materials available in aesthetic medicine. The HA used in these procedures is of non-animal origin and is obtained synthetically in the laboratory, making it virtually impossible to generate allergic reactions. It is biodegradable and resorbable, which means that the body naturally eliminates it over time. In addition, in the event of any complication, it can be dissolved with hyaluronidase, a reversibility advantage that does not exist with other types of fillers.
