I have a small area on my face with contour issues (bumps and valleys). The restylane improved it. I also had my lips plumped a little. I love the improvement. Definitely noticeable and makes a nice difference.
It was painful even with dental block and numbing cream. Maybe my dr. is a little rough. I had injections once with less pain but it was a different filler so I don't know if it was the injector or the filler.
Things I do to prevent bruising: eat fresh pineapple, no alcohol for a few days before, take Arnica Montana and eat lots of dark green veggies. I bruised a little on one of the 3 sessions.
At first I purchased just a 1/2 syringe. Then when I went back to finish the syringe I needed to buy a second 1/2 syringe (would have been $575 if I had bought a full syringe the first time -- Restylane is manufactured in 1/2 syringes and full).
Unfortunately, I have a few acne scars and the plastic surgeon said they were not deep enough or large enough to fill with Restylane so for now I'm stuck with those.
