What does fat grafting from the buttocks involve?

A fat grafting procedure involves removing fat from one part of the body, such as the buttocks, through liposuction, states the American Society of Plastic Surgeons. The fat is then injected into anther area of the body, such as the face or breasts, according to PlasticSurgery.com

Unlike a liposuction procedure that is intended to remove large amounts of fat, during a fat grafting procedure, only a tiny amount of fat is removed, says the American Academy of Facial and Plastic Reconstructive Surgery, Inc. The fat is injected into the face or breasts in tiny droplets through a cannula. Once injected, the fat droplets provide a permanent volumizing effect.
