Because the main components of hyaluronic acid are very close to their own tissues and will be absorbed by the human body, there is basically no harm and few side effects.

But it may also cause some sequelae due to their own physical reasons or improper operation by doctors:

1, redness, swelling and itching: After hyaluronic acid facial filling, it may cause temporary slight redness, swelling and itching, which can generally be relieved in a short time.

2. Congestion: For people with sensitive skin or fragile blood vessels, congestion may occur after injection of hyaluronic acid, but it will be absorbed soon.

3. Particles: After hyaluronic acid is filled in the face, the skin may have a granular touch and generally disappear in a short time.

4. Overinjection: Overinjection of hyaluronic acid is mainly caused by improper operation by doctors. The removal or dissolution of hyaluronic acid is serious, so you must find an experienced doctor when injecting hyaluronic acid.

5. Pigmentation: Pigmentation will occur if hyaluronic acid is injected too shallowly or if you don't pay attention to sun protection.

6. Infection: Hyaluronic acid facial filling is an invasive operation. Improper operation or postoperative care may lead to infection. In case of infection, patients need to seek medical attention in time.
