While BBL and butt implants are both surgeries that augment the buttocks, they do so in different ways. BBL uses your fat cells to add volume to the buttock, whereas butt implants insert medical-grade silicone implants into the glutes. As a result, butt implants give a more prominent enhancement while leaving behind a long scar in the buttock crease.  BBL is the more popular buttock augmentation surgery, primarily as it is a more organic way of achieving an enhanced buttock. However, some patients will benefit most from butt implants, particularly those with less excess body fat.
