Dr A’s Answer:
The longevity of injectable hyaluronic acid fillers (Juvederm, Restylane, Belataro, etc) depends on a number of factors. Juvederm and Restylane both have 3 product lines of 3 different thicknesses with the thickest lasting longest. The location the product is used also has a lot to do with longevity. The lips tend to be one of the fastest areas of absorption. Some people only get 3 months in the lips. Other areas like the lower eyelids can last 2 years. And of course different people absorb at different rates. I tell my lip patients that 6 months is a reasonable expectation for either Juvederm Ultra Plus or Restylane Standard (not Silk or Lyft). Of course it isn’t an all or none phenomenon, the product dissolves a little bit each day and you may choose to “refill” before it has all gone away.
