I am not sure what you are asking here. Basically if you stop using a filler then over several months to a year as the filler is metabolized the fullness will go away. All fillers stimulate collagen to a varying extent, so there is a possibility that the wrinkles will not be as bad as before you started using the filler. Good luck.
the material slowly disappears while most of the benefits gradually fade...there's a tiny amount of collagen growth that appears to accompany treatment, this stays but it's probably not clinically apparent when you look at your skin...overall...your skin goes back to what it looked like before you had your injections...no better but certainly no worse...
