How long does it take to get an injection of hyaluronic acid to reduce swelling?
Hyaluronic acid generally swells for 3-5 days before it fades. Don't touch the injection site with your hands during swelling, and don't squeeze your face at ordinary times to avoid hyaluronic acid displacement and strenuous exercise. Pay attention to clean the injection site to prevent infection. What may be painful after injection will disappear automatically after a period of time.
