Hello, the nose will swell within a few hours after it is filled with hyaluronic acid. This is normal and can be avoided. It shows that hyaluronic acid has not been absorbed. When it is absorbed, it will return to nature. If you can't eat it, it will swell up. Considering my physical condition, I am allergic to hyaluronic acid injection. It may also be the reason why hyaluronic acid is true and false.
