I have unfortunately had many patients come to me after having their high hopes for buttock/hip augmentation crushed by measly Sculptra results or other "fillers" such as Renuva and Juvederm, etc. Other than the fact that these are not FDA approved for buttock injections, here are some critical points of awareness: 1) they all are temporary, lasting 1.5 - 2 years at very most, 2) if done correctly dermal fillers like Sculptra ir Renuva are cost prohibitive for 99% of potential buttock augmentation patients. In order to create a significant/noticeable result with a dermal filler, at least 200 mls of product must be injected into each buttock cheek for a total of 400 mls. At $1000 per ml, this equates to a minimum price of $400,000.00. Thus if your doctor is recommending to put in ONLY 20 or 40 mls of these fillers you will pay $20,000-$40,000 and get an insignificant miniscule result! (eg. like a “drop in the ocean” effect), 3) Do not let anybody tell you that the product is so special that it's going to magically grow over the following months or years...this just doesnt happen to any noticeable degree!, 4) dermal fillers, when injected in large quantities, have a relatively high infection rate, guaranteed tendency to migrate away from the original area they were injected into, and almost always stimulate a lot of inflammation with a subsequent and disastrous amount of scar tissue/hardening, and 5) the one very serious complication that can rarely happen is "embolism" in which some of the filler gets into the blood stream and travels up into the lungs, heart, and/or brain causing serious problems, including death. As well, fat transfer to the hip dips, especially on lean patients, has a poor survival rate and thus often slighted results. The only relatively safe, reliable, and permanent option for buttock and hip dip augmentation is with implants. Please note, an extremely few number of board-certified plastic surgeons specialize in buttock or hip implants so you may have to travel far and away from home to find this particular surgeon. Glad to be of help.
