Most of the hazards and sequelae of hyaluronic acid injections are vascular embolism, infected necrosis of localized tissues, and allergies.
Hyaluronic acid injection can fill the tissues and make the local area full, which becomes a common way of beauty. But improper injection of hyaluronic acid may also lead to serious consequences.
If there is an injection error when injecting hyaluronic acid, embolism of blood vessels may occur, and local tissue ischemic necrosis may occur if treatment is not carried out in time. Lysosomal enzymes should be injected promptly to improve microcirculation. If too much hyaluronic acid is injected, overfilling may also lead to granuloma, resulting in stiffness of facial muscles.
A small number of people will be allergic to hyaluronic acid, skin itching, fever, red rash symptoms, at this time should be timely stopped injection.
It is recommended to inject hyaluronic acid in a regular institution, and consult a doctor when adverse reactions and complications occur.
