The Brazilian butt lift is popular because it improves the buttocks’ shape and size without implants. Since fat is extracted from other parts of the body, such as the belly, hips, and thighs, this cosmetic treatment leads to improved contouring in these areas. Women who are very lean and do not have enough fat stores may need to have buttock implants to achieve their desired size increase. If you are considering buttock implants, be aware of the complications such as capsular contracture and increased risk of infection.
