Fat injection, also known as lipofilling or fat grafting, is an aesthetic procedure that involves harvesting fat from one area of the body and injecting it into another area to increase volume and contour. This technique is commonly used for facial rejuvenation, breast augmentation and body contouring. One of the main advantages of fat injection is that it uses the patient’s own tissue, which reduces the risk of allergic reactions and rejection compared to synthetic fillers. The procedure usually begins with liposuction, where fat is removed from areas such as the abdomen or thighs. The harvested fat is then purified and prepared for injection. While the results are natural-looking and long-lasting, they can vary depending on factors such as the technique used and individual healing responses. It is important for people considering fat grafting to consult a qualified plastic surgeon to discuss their goals, possible risks and realistic outcomes.
