The appeal of a Brazilian Butt Lift is that it has transformed people figure from a square appearance to more of an hourglass shape.
Butt implants can enhance the overall shape of the buttock but typically on their own do not give patients an hourglass figure. If women have enough fat I will typically do a Brazilian Butt Lift so that I can shape their waist and then use the fat to enhance the hips and butt to give the improved shape.
In women that are very thin or want more augmentation that I can provide with fat alone I will do a combination of butt implants and fat transfer. This will allow me to shape the waist, use the implant to give the buttock an incredible shape and then use the fat to enhance the hip area creating the hourglass shape.
I hope this helps, please consult with your board certified plastic surgeon that has experience in butt augmentation.
