Having used Sculptra for 7 years, and seeing wonderful results, I can now counsel my patients that there is always a consistently good result if one is patient. We ask our patients to commit to 3 vials (one vial every 4 weeks) because it will take at least a month after the third injection to start seeing results. After that, the patient decides if she/he wants more. My average amount for each patient is 6 vials (injections), but I have gone up to 12 vials in volume depleted patients. We can't tell how fast or slow one will build collagen in response to Sculptra, but we do know that it lasts over 3 years, the results should always look natural, and the side effects are extremely few if proper injection techniques are used by the doctor. Hang in there, be patient, and 6 weeks after another treatment, compare your pre-treatment pictures. The likelihood is you will have a smile on your face.
