I had ArteFill in Canada rather than getting another restylane injection, which I used a few times, but it didn't last as long as expected.
The one thing I found different from restylane is that the dr. went really slowly with the treatment. It took about 20 minutes to complete the treatment.
He gave me numerous tiny injections into my face. The doctor told me that he goes slow in order to avoid overfilling and giving a lumpy look. After the injections he smoothed out my skin tissue to get better distribution of the artefill material.
4 months later I'm really satisfied. Very natural looking and I swear the men are giving me more attention ;)
