My doctor mixes Radiesse with lidocaine so there's virtually no pain involved. I initially got it for increasing lost volume in my face and under eye areas. In my mind, its much better than restylane.
I had little bruising and very little swelling. Its thicker than restylane so its much better for taking on the natural contours of the face without looking lumpy or strange.It also lasts about 9 months.
I'm in my mid-30s and I now look like I'm in my mid-20s again. I can't say how well it works for older patients, but it really is like a mini face-lift.
