Is fat transferred to hips during bbl or it is actually a Fat injection to buttock that gives illusion of hips?

During the process of buttock augmentation fat is  also usually injected into the hips because they are usually deficient. This enhances the overall result of the buttock augmentation. You should consult with a Board Certifies Plastic Surgeon with extensive experience performg the BBL. Good luck!

Most of the fat is transferred to the buttocks proper, rather than the actual lateral thigh or hip region.  The lateral buttock is obviously continuous with the hip region so you get improved contour of the lateral thigh.  The lateral thigh or hip can be injected but because the skin is tightly adherent to the muscle you cannot get much augmentation.   Thank you for your question.  Best wishes.
