'Unsubstantiated, sometimes fraudulent claims' for cosmetic procedures using stem cells, says Review in Plastic & Reconstructive Surgery
For Immediate Release: 07/31/2014
"Stem cells offer tremendous potential, but the marketplace is saturated with unsubstantiated and sometimes fraudulent claims that may place patients at risk," write Dr Michael T. Longaker of Stanford University Medical Center and colleagues.
'Worrying advertisements' for cosmetic stem cell procedures
Dr Longaker and coauthors raise concerns about the unregulated use of stem cells for unproven indications—including cosmetic procedures.
While stem cell therapy "remains in its infancy," they write, "there are a growing number of cosmetic practitioners that are advertising minimally invasive, stem cell-based rejuvenation procedures."
The article was prompted by "worrying advertisements" claiming benefits of stem cell procedures for facelifts, breast augmentation—even "stem cell vaginal rejuvenation." These ads claim benefits from procedures that have not undergone rigorous scientific evaluation—including potential risks related to stem cell and tissue processing and the effects of aging on stem cells.
To gain insight into these claims, Dr Longaker and coauthors performed a Google search for cosmetic stem cell treatments, the most common of which was "stem cell facelifts." Most procedures used "stem cells" isolated from fat. However, the websites provided little information on the quality of the stem cells used.
Without advanced cell-sorting procedures, these products used in these procedures likely contain many other types of cells besides fat-derived stem cells. Many clinics also offered plasma-rich platelet protein treatments, which they inaccurately marketed as stem cell therapy.
Despite evidence that is "minimal at best," advertisers are also claiming that their stem cell treatments have "anti-aging effects." The authors note that procedures marketed as "stem cell facelifts" are often just "lipofilling" procedures—an established fat injection technique with no prolonged anti-aging effect.
