Hello and Great Question. I appreciate the time you are spending researching this procedure. My name is Dr. Matthew J. Nykiel. I am a Board Certified Plastic Surgeon, a Fellowship Trained Cosmetic Surgeon, and a Butt Augmentation Specialist. In my practice, a BBL start at $7,900. What does that include? It includes: all pre/post care, preop labs, Surgeon, OR, and Anesthesia Fees! What is specifically performed in my procedure? In my hands, a BBL includes proprietary techniques of: Advanced Liposuction of the Torso (Abdomen, Back, Flanks, Thighs, and Butt) with Fat Separation/Washing/Transfer into the hips and butt. What are the details of the procedure? A Brazilian Butt Lift is achieved first by sculpting the torso: abdomen, flanks, waist, butt and hips with liposuction. In my practice, I have many different forms of liposuction (power, energy (laser), sound (VASER). I typically utilize a combination of the various liposuction techniques to perform LipoSculputre to help create the hour glass. In addition, the advanced technology helps to improve the skin quality (tightens and firms). The most important part of liposuction is the surgeon performing it; and then the next most important feature is the technology behind the liposuction. Lipo is no different than other products, typically Better Tech=Better Results.After liposuction, the fat is then processed and purified. The purification process is extremely important. When fat is harvested there is a bunch of "junk" that comes with it (water, blood, tissue etc); injecting a high concentration of this "non-fat" particles will cause your butt to be swollen initially; but will decrease with time! In fact, I believe this is the reason why some people complain that their Brazilian Butt Lift did not last (after the swelling went down). Why am I discussing this? Because, unfortunately, the fat separation/purification takes time in the operating room; and this is not something that can be "sped-up" and definitely not something you want "short-cutted"; in my opinion this is THE most important portion of the fat transfer and is a major contributor to the fat "take". In my practice, I utilize a proprietary technique to separate, isolate, wash, and clean the fat.Finally, after the fat has been harvested and cleansed it is injected. In my practice, I utilize the fat to first sculpt and create the hour glass in the hips and outer butt. I perform this artistic sculpting by moving you from side to side in order to sculpt in 3 dimensions. Once we have achieved the right frame (hour glass), then I fill and volumize the butt. This creates the bubble or heart shape that is desired. Again, the sculpting and volumizing of the butt if performed in all 3 positions (side, side, back/buttt) to sculpt the butt in 3 dimensions.In regards to your specific questions about your measurements: The Brazilian Butt Lift is going to bring in your waist/torso measurement. This is because we need sculpt your waist/torso into an "Hour-Glass" with liposuction. An interesting optical illusion takes place, as the waist shrinks and gets smaller the eye perceives your hips as getting significantly larger! Then, fat is transferred into your hips in-order to widen the hips. The widening of the hips makes a more noticeable and significant hour glass. Will your hip measurement increase by 6 inches? It really depends on how much your skin will stretch to accommodate the fat transferred and typically that requires either a virtual or in-person consultation. Best of Luck!
