7 month post op Restylane.
If you are unhappy with the results schedule a follow up with your injector and discuss a hyaluronidase injection to remove the product.
Best of Luck.
If you feel that there is swelling it is possible that there is still product there. I would go to a reputable injector and have then take a look and a feel. If they think that there is scar tissue they might inject steroids but if they think that this is product then they can inject hyaluronidase and dissolve it. It is possible that you had too much product or that it was injected too superficially. I have never seen Restylane scar so have faith. Probably will eventually reverse itself. See someone you trust
