Any treatment may have side effects. The most common and slightly self-healing side effects such as injection of hyaluronic acid are cyanosis and mild swelling. If the bruise and swelling are obvious, it will recover in a week or so.

However, if there are complications such as nodules, infections and skin color changes after injection, you should go back to the injection hospital as soon as possible to seek coping strategies. If the above complications occur after injection, timely treatment within 4 hours can minimize the impact. After 12 hours, the interventional treatment has limited effect and may leave injuries.

The possibility of serious complications such as infection and blindness after injection can be minimized by selecting regular medical institutions, regular qualified medical personnel and using injection materials approved by the state.
