It is reported that some domestic beauty medical institutions and beauty salons illegally sell and use sodium hyaluronate for injection from time to time. Some illegal organizations or individuals pull "business" through the Internet and inject sodium hyaluronate into consumers without obtaining the registration certificate of medical devices, thus forming an underground industrial chain for illegal profiteering.

According to the notice, the special action is divided into three stages: centralized rectification, special supervision and summary and consolidation, so as to effectively safeguard the legitimate rights and interests of consumers and ensure the safety of their computers.
