Dear Pam Jones:
I personally have seen fillers injected in the tip of the nose last for two years or longer but the duration varies. If injected in an area with low mobility hyaluronic acid fillers last longer. In some patients, I will use Radiesse to increase longevity. You would want to have Juvederm Ultra plus rather than plain Juvederm ultra for a better last.
All the best, Dr. Clark
