A fat transfer is a surgical procedure that removes fat and stem cells from one part of the body to another, recipient site. Also known as fat grafting, the goal is to take unwanted fat from a specific area such as the stomach or thighs and use it to augment the size of another part of the body like the face or breasts. Alternatively, your body’s own stem cells can be harvested from the fat and those stem cells can be utilized to rejuvenate your facial structures, without adding any fat.
