A review of complications of polyacrylamide hydrogel injection
Abstract
Once a popular injectable filler, polyacrylamide hydrogel (PAAG) has been banned in China since 2006 due to its unclear safety and long-term complications. However, it is still being used worldwide because of its huge commercial profit, leading to emerging complications and an urgent need for standardized clinical management. This review aimed to assess the properties, safety, and complications of PAAG and treatment strategies for its removal.
