I Had Restylane injected into my nasal folds in 2007. The results lasted for about 1 year. I was very satisfied. The injections were uncomfortable but I have a high pain tolerance. I bruised from the injections that lasted about 3 weeks.
Then I decided to try Radiesse. I wasn't satisfied at all. I couldn't tell I had anything done. I had knots under my skin and bruises that lasted for about 1 month.
I wouldn't recommend Radiesse at all, isn't worth what it costs. 500 for Restylane versus 800 for Radiesse.
