Juvederm® helps replace the naturally hydrating substance in your skin that keeps away unwanted wrinkles and those parentheses lines on your face. As you age, time, sunlight and other factors from living can reduce the amount of hyalurnic acid (HA) in your skin. This lack of HA causes your skin to lose volume and structure.  Juvederm® looks to replace the HA your skin has lost, adding volume to smooth away facial wrinkles.
