Juvederm is a hyaluronic acid filler that is used to fill the nasolabial folds. As a master injector for over a decade, Dr. Iyengar has extensive experience in the use of Juvederm to reduce the hollowness that develops between the nose and lips. This is essentially painless with the topical numbing cream that we use in the office. Dr. Iyengar regularly has training physicians come to observe his injection techniques.
