Hello,The lure of using Sculptra is great, given it's popularity on social media. However, one thing should be made abundantly clear: it is very expensive. The use of Sculptra for the aging face (for which it is FDA approved) usually requires 4 to 8 vials and lasts around 2 years. Knowing that this many vials is used on the face to subtly change its contours, you can expect you'll need much, much more to 'inflate' the buttocks. In general, people see a modest change (after about 2 months) with 20 to 30 vials. Physician cost per vial is about $350, so the doctors product cost is about $10500 for 30 vials without an injection fee, which can vary from doctor to doctor. This approaches or equals the cost of a surgical fee for liposuction and fat transfer, but it eliminates downtime and pain (mostly). I hope this sheds light on this subject. Best of luck!
