Injection of hyaluronic acid may lead to skin allergic reaction, which may be due to the allergic reaction of individuals to hyaluronic acid. Mild people may only have red, swollen and itchy skin, and severe people may have symptoms such as difficulty breathing.

In the process of injecting hyaluronic acid, if the local nerve is damaged, it may affect the functional imbalance of movement or sensation, such as unnatural and stiff facial muscle activity.

During the injection of hyaluronic acid, the blood vessels in the face will be damaged and there may be a risk of vascular embolism. If hyaluronic acid is injected into blood vessels, it may lead to vascular embolism, and in severe cases, skin necrosis and visual impairment may occur.

Excessive or improper injection of hyaluronic acid may cause hyaluronic acid to stay in the skin for too long, thus causing skin deformation or other adverse reactions. For example, excessive injection may lead to excessive fullness or induration of the skin.

Injection of hyaluronic acid may also lead to the risk of infection. If an unclean syringe or needle is used during injection, or improper postoperative care may lead to skin infection.

Therefore, when choosing to inject hyaluronic acid, we must choose regular medical institutions and professional doctors for consultation and treatment. Before the injection, the doctor will conduct a skin allergy test to ensure that there is no allergic reaction. At the same time, postoperative care and preventive measures are needed to reduce potential risks and complications.

In a word, although injecting hyaluronic acid is a relatively safe plastic surgery, there are still some potential risks. Choosing regular medical institutions and professional doctors for consultation and treatment, as well as correct postoperative care and precautions are the keys to reduce potential risks.
