Juvederm is an injectable facial filler that contains hyaluronic acid, a chemical that is found naturally in the skin and helps maintain the skin’s youthfulness.  Juvederm is FDA approved to reduce the appearance of lines around the mouth such as smile lines (the crease that runs from the corner of your nose to the corner of your mouth), marionette lines (the crease of skin that starts at the corner of your mouth down your chin) and for lip augmentation.  The results can be significant and can last up to one year.
