Butt implants were once the primary way to augment the buttocks. However, they have largely fallen out of fashion for a variety of reasons. First, they do not look or feel as natural as transferred fat. Secondly, any implant in the body can cause issues. Though, butt implants showed a tendency to create more problems, both over time and during recovery. Finally, butt implants require lifting the muscle of the buttock which involves a much more painful recovery.
There are still a few surgeons who specialize in buttock implant surgery. Additionally, there are still a few rare instances where butt implants may be the preferred augmentation method. However, as buttock enhancement methods advance, this is becoming less true.
