I had Perlane injections for nasolabial lines performed by a doctor whilst on a cruise.
The injection on one side of my face was exceedingly painful, whilst the other side was just a sting. The doctor told me that it was because he had to inject twice as much Perlane into the painful side. One side ( the less painful ) has been a good result, whilst the other side has not.
The doctor did give me a correctioal injection of a different substance. He didn't tell me what it was when I asked. I still cannot see a difference. He also told me that it would last approximate. 12-18 months. The cost was $900.
