Personally, I can not say for sure if it was worth it or not. My injections were done back in October 2009.
After reading all the postings on this site, not sure I would use Sculptra again. I have not had any side effects yet, however I used a homedics massager on my face 2-5 xs a day for weeks. $800 for 1 vial is expensive. I would probably use another product if I had to do over again. I do notice less hollowness in cheek area, but that is about it.
