What are the hazards of blunt needle injection of hyaluronic acid

The common hazards of injecting hyaluronic acid are as follows:

1. Hazards during injection: If you do not pay attention to aseptic operation during injection, it will cause infection, bleeding, and hematoma and mass will be formed;

2. Serious complications: If hyaluronic acid is injected into a blood vessel, it will cause blood vessel embolism, and the blood vessels will dominate the surrounding skin. If the soft tissue is embolized, necrosis will occur, resulting in necrosis of facial skin and soft tissue, and obvious scarring will be formed. If the thrombus enters the blood vessels of the fundus with the blood, it will cause blindness, and if it enters the blood vessels of the brain, it will cause cerebral infarction, hemiplegia, and aphasia;

3. Rejection and inflammatory reaction: If the injection of drugs is not regular, there will be rejection and inflammatory reactions, such as redness, swelling and swelling.
