What are the side effects of hyaluronic acid injections?

Common complications of hyaluronic acid injections include swelling and bruising, risk of infection, uneven skin texture, allergic reactions, and vascular embolism.

1. Swelling and Bruising: Tissue damage from the injection often results in localized swelling and bruising after the procedure. Swelling is usually noticeable within hours to days, and bruising generally subsides within approximately one week.

2. Risk of Infection: Improper technique or inadequate post-injection care may lead to infection, causing increased redness, swelling, pain at the injection site, and purulent discharge.

3. Uneven Skin Texture: Inaccurate dosage control or uneven injection depth by the physician may result in an uneven skin surface, affecting facial aesthetics.

4. Allergic Reactions: A small number of individuals may be allergic to impurities or added components in hyaluronic acid, experiencing symptoms such as skin itching, redness, and swelling. Severe allergic reactions can be life-threatening.

5. Vascular Embolism: Injection of hyaluronic acid into a blood vessel can cause vascular embolism, leading to local skin necrosis and tissue loss. If this occurs around the eye area, it may result in blindness.

Prior to the procedure, it is important to consult thoroughly with a physician to determine whether your skin condition is suitable for hyaluronic acid injection. After the procedure, follow medical advice carefully, ensure adequate rest and proper post-injection care, and avoid touching the injection site to prevent infection. If any abnormal symptoms occur, such as persistent redness, swelling, pain, or changes in skin color, seek timely medical attention.
