Fat transfer for aging skin: technique for rhytids.

Dermatologic surgeons are familiar with many surgical and nonsurgical techniques for the reduction of facial rhytids. Injectable collagen, silicone, and fibril are commonly employed as injectable filler materials. Properly done, fat transfer is another valuable tool for use in facial restoration. Fat transfer is an excellent technique for intervention in the aging process, and is easily managed as an office procedure. We will review the near-century-old history of fat grafting and outline the structural dynamics in the process of facial aging. Our experience from the last 50 fat transfer procedures performed will be reviewed with specific attention to patient selection, extraction and injection technique, complications, and overall results.
