With the growing trend to have more balanced, full buttocks, butt implant procedures are one of the fastest growing cosmetic procedures today. Butt implants, also known as butt augmentation, is the enhancement of the buttocks through either invasive or non-invasive options. Implants are inserted with a soft but strong implant called elastomer. Unlike with breast implants, elastomer doesn't leak. Also available, fat grafting procedures. Fat is taken from other parts of the body (abdomen, flanks, hips, lower back or thighs), purified and preserved, then injected into the buttocks. Although less permanent, fat grafting is growing in popularity.
