Hello cammm, It’s a pleasure to answer your questions! Injectable Silicone, Biogel, Hydrogel, and Biopolymers used for body contouring are not FDA-approved and can cause serious side effects that may be permanent or may even lead to death. Side effects can include ongoing pain and serious injuries, such as scarring, tissue death, and permanent disfigurement. If the silicone migrates beyond the injection site, it could cause an embolism (blockage of a blood vessel), stroke, infections and death. Serious complications may occur right away or could develop weeks, months, or years later. Instead of Biogel injections and other foreign material injectable substances that are deemed medically unsafe, I would recommend you getting a VASER Liposuction with fat transfer to the buttocks (Brazilian Butt Lift (BBL). Many of my patients chose to have excess fat removed from specific areas of the body such as arms, back, abs and flanks with VASER Liposuction and transfer it to the hips and buttocks to get a beautifully contoured figure. Fat cells treated and removed during VASER Liposuction are typically of high quality, and are viable to re-introduce into the body in a fat transfer procedure. Unlike short lasting synthetic fillers, re-injecting your own fat may give you natural looking results that last longer, with no risk of rejection. Consult with an experienced plastic surgeon to assess your candidacy for a Brazilian Butt Lift and discuss your particular needs and cosmetic expectations. Best regards! Dr. De La Cruz.
