A Brazilian Butt Lift (BBL) is a type of plastic surgery that involves removing fat deposits from other parts of the body and injecting them into the buttocks to improve their shape and size. During the procedure, a plastic surgeon removes fat from areas such as the hips, abdomen, lower back, or thighs using liposuction, purifies it, and then injects it into specific points on the buttocks to increase volume and improve shape. The procedure is also known as gluteal fat grafting, buttock augmentation with fat grafting, and safe subcutaneous buttock augmentation (SSBA). It is important to note that a BBL is not a traditional "lift" procedure like a facelift or breast lift despite its name. Instead, it adds volume to and improves the shape of the buttocks.

A good candidate for a BBL should be finished developing, in good physical health, have realistic expectations, and have enough excess fat in other parts of the body to be used for the procedure. However, a BBL is not recommended for individuals with sagging or excess skin in the buttock area.

While a BBL can give a smaller-looking waist if the fat comes from the belly or lower back, it is not an actual "lift" because it doesnt try to raise the buttocks. The procedure is considered semi-permanent, and the results can last for years and even more than a decade. However, maintaining weight can help the results last.

It is important to note that a BBL can be risky and even fatal, but it is considered safer than other procedures to change how the buttocks look. In recent years, surgeons have changed the way they perform the procedure to make it safer. However, it is still important to choose a skilled cosmetic surgeon and be aware of the risks involved.
