What are the symptoms of hyaluronic acid embolism?

Hyaluronic acid embolism may result in swelling or pain, and bruising may also occur. It is primarily caused by improper technique, such as accidentally injecting hyaluronic acid into a blood vessel. This can lead to localized severe pain, swelling, and bruising. In more serious cases, it may even cause tissue necrosis or ulceration at the injection site. Hyaluronic acid embolism can be treated by injecting hyaluronidase, an enzyme that dissolves hyaluronic acid and promotes recovery. Local heat application may also help.
