As with any cosmetic surgical procedure, Brazilian butt lifts carry certain risks of complications. Compared to more invasive cosmetic procedures like butt implants, the complications associated with Brazilian butt lifts are relatively minimal. This is because the incisions made are extremely small (less than 1 mm) and are generally positioned and directed so that they leave minimal scarring. Also, your surgeon will use a blunt cannula (hollow stainless steel tube) in conjunction with an internal syringe, thus reducing the possible harms that could occur with a sharper instrument such as a needle.
