I am a 64 year old male who underwent Artefill injections one year ago.
The doctor injected two syringes, 0.8cc each. Discomfort was minor with little or no swelling or bruising. The improvement was less than I had hoped for. It reduced the depth of the folds about 50%.
In hindsight, I probably needed at least twice as much filler, but the cost would have been prohibitive.
