Buttock volume can be deemed insufficient either naturally (from the end of puberty), after weight loss (generally resulting in sagging skin), or simply over the years.
Buttock implants not only increase the volume of the buttocks, but also lift them to give or restore a satisfactory shape. Prostheses are now preferred to lipofilling (injection of fat into the buttocks, after removal from the abdomen, for example) for safety reasons (increased risk of embolisms).
For more moderate volume gains, stimulation of the gluteal muscles using “B-Tonic” electromagnetic technology can also provide a less invasive solution.
