Fat Injections: A Boon or a Bust?

The popularity of fat injections has risen and fallen, and appears to be on the rise again. The realization that many of the facial changes of aging are due to the loss of volume of both soft tissue and bone, has dramatically increased the use of fillers. Because the commercially available fillers are relatively expensive, fat grafting has been attractive as a relatively inexpensive source of a large volume of filler material, material that is native to the patient and should not cause allergic reactions.
