Areas wanting treat: Jowls and forehead. It has been suggested to use sculptra with these modalities. I am trying to decide between the two modalities& providers. It was expained to me that sculptra can be infused with the Potenza with an option to have sculptra cannulated and delivered deeper with my third treatment if needed. How important is experience..or is it device dependent? So far, as i have read, Potenza seems to have better ratings for the face. What is your experience?
