Longevity with fillers is variable, not only do different people respond differently, but different areas on the same patient can have different results. Although Restylane persists for about a year, I think the visible effects last 4 to 6 months and then gradually begin to dissipate. Some people metabolize it more slowly than others, which means they have longer lasting results. Also, in areas that have a lot of movement (the lips), fillers tend to disappear more quickly. As Dr. Schreiber mentions, there is evidence that multiple treatments over the course of a few months leads to longer lasting results.

Restlyane results depend on patient
Restylane lasts about 12 months
Restylane may last up to 12 months! Everyone is different, and I've seen it last longer and go away faster. For optimal results with Restylane, you may need 2-3 treatments space out by 3 months. This way, the Restylane can build on itself to give a great result that is long-lasting.
