I have used fillers several times- mostly Restylane- in the lines/folds on the sides of my nose. I always like the results but it is expensive. I saw Hydrelle on The Doctors and thought I would try it since it was touted as more "filling" than other products.
I only had to use 1 syringe- I usually had 2- and it barely hurt. I would give it a 3 in pain/discomfort. I was a little more swollen but not much and my doctor said that he was more conservative because it can cause more swelling. It has been 6 months and I still have my results.
