It’s been almost a month since the LA Times ran the article by Chris Woolston entitled The Healthy Skeptic: Stem cell face-lifts on unproven ground. It’s well written and presents a fairly balanced view. While I am a fan of stem cell research, I think the “claims” are often put ahead of the science. This is one of those times. I can’t find any decent articles to support the claims of the plastic surgeons doing “stem cell face-lifts.”
My view is echoed in the article (bold emphasis is mine):
Rubin says he’s excited about the potential of stem cells in the cosmetic field and beyond. Still, he adds, there are many unanswered questions about the cosmetic use of stem cells, and anyone who claims to have already mastered the technique is jumping the gun. As Rubin puts it, “Claims are being made that are not supported by the evidence.”
While researchers in Asia, Italy, Israel and elsewhere are reporting decent cosmetic results with injections of stem cell-enriched fat, Rubin says that nobody really knows how the stem cells themselves are behaving. He points out that fat injections alone can improve a person’s appearance, no stem cells needed.
Rubin believes it’s possible that injected stem cells could create new collagen and blood vessels — as they have been shown to do in animals studies — but such results have never been proved in humans. And, he adds, the long-term effects of the procedures are an open question.
Stem cell face-lifts could someday offer real advances, says Dr. Michael McGuire, president of the American Society of Plastic Surgeons and a clinical associate professor of surgery at UCLA. But he believes that scientists are still at least 10 years away from reliably harnessing stem cells to create new collagen and younger-looking skin. Until then, promises of a quick stem cell face-lift are a “scam,” he says.
