My chin swelled up a few years after getting hyaluronic acid injections

Swelling after injecting hyaluronic acid into the chin for several years may be related to delayed inflammatory response, material displacement, or infection. It is recommended to seek medical attention promptly to investigate the cause and have a doctor evaluate whether intervention is necessary.

Hyaluronic acid, as an absorbable filling material, usually gradually metabolizes within 6-18 months. But in rare cases, swelling may occur several years after injection due to incomplete degradation of the material or local immune reactions. Common manifestations include persistent redness, tenderness, or induration in the injection area, and some may be accompanied by systemic symptoms such as low-grade fever. At this point, ultrasound or magnetic resonance imaging should be used to determine the presence of complications such as granulomas. More rare cases are secondary infections or vascular compression. If the swelling suddenly worsens and is accompanied by severe pain, skin turning purple, or changes in vision, emergency treatment is required. Doctors may choose to inject anti-inflammatory drugs, treat with lytic enzymes, or surgically remove residual materials based on the situation. Avoid rubbing and pressing the injection site in daily life, and promptly follow up with the original injection doctor if any abnormalities occur. Choosing reputable medical institutions and certified hyaluronic acid products can reduce long-term risks. After surgery, it is necessary to follow the doctor's advice for regular check ups and avoid high temperature environments or intense exercise. If accompanied by allergic symptoms such as itching and rash, contact with suspected allergens should be immediately stopped and anti allergic treatment should be received. Keep your face clean and avoid using irritating skincare products.
