Does Sculptra cause scar tissue? (Photo)

39 F. I'd like to reduce the marionette lines and mental crease, tighten jaw, and add subtle volume to cheeks. I was recommended Sculptra at a consult and was very excited about it until I read claims that it doesn't stimulate healthy collagen, only scar tissue. Could this be true? If so, are there other non surgical options for me? I'm not interested in hyaluronic acid based fillers or thread lifts.
