Can I get hip injections and how much would they cost?

Fat transfer to the hips is commonly performed as an adjunct to a gluteal augmentation but may be performed independently. The fat is harvested from areas of relative excess and delivered to areas of relative deficiency.Cost will vary from procedure to procedure, surgeon to surgeon and region to region.
The easiest way to determine a price range is by contacting local providers. RealSelf.com is also a helpful resource for establishing a price range in a given area.
As always, discuss your concerns with a board certified plastic surgeon (ABPS).

The short answer to your question is yes you can. The Brazilian Butt Lift is a procedure in which fat is liposuctioned from different areas of the body, most commonly from the abdomen, waist, love handles, and lower back, and the fat is then transferred to the buttocks. In your particular case, if it is determined that you are a good candidate, you can have fat transferred from the abdomen or thighs and onto your hips.
You should find a plastic surgeon who is board certified and an expert on this procedure. I also encourage patients to review content of the plastic surgeon’s work, and preferably read upon reviews located on reputable sources from patients.

I hope that answers your question on Brazilian butt lift. It's great you're doing your research. I always say that the best patients are informed patients.
Thanks for reading and best of luck on your journey!

Hip augmentation for an hourglass figure can be achieved through the same means as
a Brazilian Butt Lift. Fat removed via liposuction from other areas of the body, including
the abdomen, thighs and arms, can be transferred to the hips to provide curvier
contours.
If you have already received a Brazilian Butt Lift, talk to your doctor about when you
would be ready to undergo another procedure. If you are planning on having a Brazilian
Butt Lift and have yet to undergo the procedure, be sure to discuss adding volume to
your hips during your initial consultation with your doctor.

Hope this helps! If you have any further questions about hip augmentation via fat
transfer, talk to a board-certified doctor. Hope this helps.
