Fat grafting treatment is typically performed under a light anesthetic. Initially, an appropriate amount of fat is harvested from another part of your body, typically the abdomen, thighs, flanks,  or buttocks. Because your own tissue is used for fat grafting, there is no need for allergy testing. The harvested fat is processed and purified. Fat cells can then be injected into the face through a fine needle, precisely enhancing volume in the desired area.

Fat transfer surgery can take anywhere from an hour to more than four hours. Timing depends on your specific case. For example, lip fat transfer takes about an hour. Breast fat transfer can take between three and four hours.

During fat transfer surgery, your plastic surgeon:

• Uses liposuction to remove excess fat from one area of your body.
• Purifies the fat.
• Injects the fat in tiny droplets into the desired area.
