The procedure was mild with very little discomfort. My cheeks have always been flat, so I wanted to accentuate them. I had 3 treatments and I have great cheek contouring now. My eye circles have also diminished. I have not had any problems with bumps; it must be the experience of the injector. I have also noticed this product did more for tightening my skin than 3 fraxel treatments. I have had a great experience and love my new well-placed facial volume. It took some time to see results, but they came!
