How much are butt injections? How many days do I have to miss work?

Sculptra Instant Butt Lift is a nice alternative for someone looking to add volume to the buttocks but is not interested in surgery.  The procedure can be done in the office with minimal bruising.  You can sit on the area immediately.  You will not need any time off work.  Multiple treatments are often necessary based on desired results and are performed 6 weeks apart.  I recommend visiting with an expert injector in your area to learn more.

Keep in mind, the buttocks need numerous vials of Sculptra over time to build volume, and in some instances the results are subtle and will need to be combined with fat or implants to achieve desired results. Cost will vary due to skills, technique and expertise. There is no downtime with the procedure. I recommend seeing a body shaping expert for a formal evaluation.  Best, Dr. Emer.

the mechanism of action of Sculptra is to encourage collagen formation in a way that allows building volume, allowing us to restore youthful shape to faces. It typically takes 8-12 months to see the final result. 
The buttock, like the breasts, have shape and volume predominantly due to fatty tissue. A better and less expensive option is the Vampire or PRP (platelet rich plasma) procedure. The final result is typically seen 3-4 months after injection. 
The cost for Sculptra is going to be expensive because it takes many vials to make a noticeable improvement in the volume of a buttock. Likely 3-5 vials per buttock, (6-10 vials for both) at a cost of $750-$850 per vial, depending where you go. 
The cost for the Vampire procedure would likely be $1500-$3000 for both buttocks, and likely give you more volume and natural feel than the Sculptra. (And I am telling you this as one of Sculptra’s biggest fans!!!)
I hope that helps.
