However, I think that the manufacturer does a MUCH better job training physicians in proper injection technique of Sculptra as compared with other agents. They supply the physician with ample printed and video materials and seminar opportunities, also live seminars, hands-on seminars (patient volunteers), and webinars. They will fly in a trained physician for you. They will supply physicians with continuing education opportunities. However, as in all learning situations, a student (in this case, a doctor) may interpret the information differently. Also, there can be differences in results based on dilution(s) of the agent, injection technique, eye-hand coordination, dexterity, knowledge of anatomy, knowledge of the aging face, artistic interpretation, physician-patient dialogue, etc. Continuing medical education (CME) is important with Sculptra, as new techniques are evolving. I recommend that you ask your doctor to show you pictures of some of their patients("before" and "after" photos). Regards.
