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.
