Had Restylane injections and loved it. It lasted about 6 months for me. Decided to try Radiesse. Heard it would last 12-18 months. Had 1 syringe with very bad swelling and bruising. Went back 2 weeks later for another syringe for more volume. Less swelling and bruising with the second syringe. Was happy with the results but it was completely gone by 3 months. Will be going back in 2 weeks for Juvederm. My PS doesn't use Restylane. Hoping for more lasting results. Don't recommend Radiesse.
