Doctor's answer (1)
Dr. Han Xuefeng
After hyaluronic acid injections, swelling and firmness may occur postoperatively, which is a normal reaction and can last for several weeks or even months. After six months, the symptoms of swelling and firmness should gradually subside, as hyaluronic acid is metabolized in the body and does not persist indefinitely. However, if the swelling and firmness continue beyond six months, it is best to consult a doctor at a hospital. Based on the patient's specific condition, the doctor can provide an effective treatment plan for these symptoms.
