I want to get hyaluronidase to dissolve juvederm voluma from an overfilled side of my cheek in a small area close to the nose on one side of my face, but am worried about adverse reaction. Could taking prednisone before injection help in preventing allergic reaction and/or swelling? I really want to match the overfilled side of my face with the more natural looking side rather than add filler to balance out the difference. Thanks.
