Can the fat used in BBL's come from your face?

Thank you for your question.Yes, it is possible. To provide a valid medical opinion I will need to see pictures of you body from different angles. I would suggest to be treated by board certified plastic  surgeon with experience in this procedure, to get the best desired results.

Hello,thank you for your question. Yes, this fat can be harvested to used it for your BBL, fat can be harvested from the abdomen, flanks, thighs, arms, back, etc. and transferred to the hips and buttocks. I recommend you to schedule a consultation with a board certified plastic surgeon for proper evaluation. 

Dear searchforcurves,
generally speaking, it is possible to use fat from any body area. However, it is hard to expect that you have enough fat in your face in order to get a bigger increase in size. If you are considering a surgery, I would suggest you to consult a board-certified plastic surgeon. Only after a thorough examination you will get more information and recommendations.

Hello dear!
Thanks for the question and provided information as well.
Fat can be harvested from many areas: arms, chin, abdomen, back, flanks, thighs, etc.
In general, you need to be physically healthy and at a stable weight, have realistic expectations, be a non-smoker and your BMI needs to be 30 or less.
l recommend you to make an appointment with a board certified plastic surgeon to talk about your goals and anything you need to know.
Good luck :)

Patients do not need a lot of fat to have a successful BBL. High defintion VASER liposuction has changed fat transfer and fat grafting. This way patients with smaller builds and less fat can still get amazing BBL results. If you are a good candidate for a Brazilian Butt Lift (BBL), the optimal outcomes are achieved with: 1) use of VASER liposuction to harvest the fat, 2) a closed looped system such as Puregraft to process the fat, and 3) strategic micro-packet transplant technique. These three processes have demonstrated over 95% fat graft take. This means that your results will be stable as long as you maintain your weight. As an official VASER trainer, I am routinely referred unhappy BBL patients. One of the most common reasons for disgruntled BBL patients is that patients are not able to accurately communicate their desired buttocks goals to their surgeons.  A buttocks assessment tool can be an invaluable tool to communicate to your surgeon the exact buttocks size and shape you are desiring. A Skype or FaceTime consultation with a BBL specialist can help you get an accurate recommendation and pricing.

Any fat can be used for a fat transfer. It’s unlikely your face would contribute enough volume to have any substantial impact on a BBL procedure.Facial liposuction is tricky and most providers only do limited liposuction in the face because of the potential risk of injury to the facial nerve and other important structures.Best, Mats Hagstrom MD
