As with other Hyaluronic Acid fillers, Teosyal and Juvederm will be absorbed naturally by the body over time.  Some people will metabolize it faster than others. The duration of the filling effect varies based on the facial areas treated, the thickness of the product used, and other factors such as the structure of the skin, lifestyle and age. We lose Hyaluronic Acid faster if we spend a lot of time in the sun.  The result lasts longer in areas less affected by animation.  When used to plump up a scar the result will last longer than when used around the mouth, for example, where there is much more movement. Timely touch-up and follow-up treatment will add to the duration. Results from fillers generally last from 6 months and for periods up to 2 years in most people.
