Is there a risk of hyaluronic acid?

Hyaluronic acid injection is a common plastic surgery method in clinical practice at present, which can be used to fill human facial muscles, such as nose augmentation, lip enrichment, etc. The substance itself can be absorbed by the human body, so it generally does not cause harm. However, if the hospital is not regular, or the injection process is improperly operated, it may cause skin infection and necrosis of human body.
