Now, plastic surgeons are experimenting with a first-of-its-kind body filler derived from—guess what—fat. Donated human fat, to be exact, which has been procured from cadavers and meticulously processed into a thick injectable called Alloclae. Donor tissue—which includes everything from skin and cartilage to ligaments and heart valves—is frequently used in all fields of medicine, including aesthetics, but for some patients, the idea of receiving “fat from a dead person is still a little macabre,” says Troy Pittman, MD, a board-certified plastic surgeon with practices in Washington, DC, and New York City. To secure the donor adipose tissue—aka fat—Tiger Aesthetics, the makers of Alloclae, partners with recovery agencies who “work closely with healthcare providers and family members of donors to review the scope of the deceased individual’s donation,” says a representative for Tiger. Some of you may be morally opposed to (or just totally turned by) the idea of using human parts for cosmetic purposes and will choose to avoid Alloclae just as you might forgo Botox (which contains albumin, a protein in human blood) or exosomes (which are commonly sourced from human cells).
