Sabrina Fabi, MD, and Hema Sundaram, MD, two well-known dermatologists, assessed the potential of topical and injectable growth factors and cytokines for facial rejuvenation in an April 2014 article for Facial Plastic Surgery. And three other dermatologists, Flor Mayoral, MD, Julie Kenner, MD, and Zoe Draelos, MD, put peptides and growth factors at the top of their “skin health and beauty pyramid,” a clinically based guide designed to help physicians select and recommend topical skincare products (J Drugs Dermatol, April 2014).

“Lifeline Skin Care has had its products tested in several independent clinical trials that have shown amazing results, including improvement in wrinkle depth and skin firmness from 55% to 80%,” says Craw. “Summaries of the studies are available by request.”

CeLuvia also offers in-house studies. “Our products go through clinical testing under the supervision of expert dermatologists to examine efficacy and safety. This is an extremely important part of our process,” says Bacus.

“U Autologous skincare’s eye cream by Personal Cell Sciences was tested in an independent, eight-week clinical study by Dr. Fredric Stern of Bellevue, Washington. The study showed promising results using the individual’s own stem-cell-based conditioned medium,” says Ensley.

“When evaluating clinical studies, the user should be made aware of who performed them and how,” he says. “Ideal studies are performed by disinterested outside experts and involve control groups and blinded evaluators, but all types of studies can help users understand how the product may work best for their purposes.”
