Fat transfer, also known as fat grafting or fat injection, is a cosmetic procedure that uses your own body fat to enhance and restore facial features. It addresses various age-related concerns. This treatment targets signs of aging by smoothing wrinkles and folds around the eyes and mouth—including nasolabial folds, marionette lines, and the prejowl area—while also enhancing cheekbones and refining the contours of the jawline and chin. It can address under-eye hollows, define the temples, and create a more balanced facial structure.
