How long will this Restylane in my forehead last?

I have seen your posted picture of this service and I think it is remarkable it did not blind you.  This is not a good place for filler.  Do not patiently wait for this overfill to go away on its own.  It needs enzyme to break it up.  Best.

Rest assured, the filler will dissolve on its own, but Restylane may last anywhere from six to eighteen months, depending on the formula and the area of the face. Fillers in more mobile areas like the lips have a thin, flexible texture and do not last as long as more dense fillers such as cheek and wrinkle fillers. Best, Dr. Emer.

Fillers will typically last 6-12 months. In areas with less movement like the forehead, it may be closer to 12 months. Besides waiting for it to dissolve, you can try to massage it down by simply pushing on it and spreading out the filler. Alternatively you can have it injected with a compound to dissolve the filler. it depends on how much it bothers you. 



Good luck!
