Is science catching up with the hype about anti-aging skin creams and the claims of restorative benefits? “Maybe,” says Valerie Goldburt, MD, PhD, of Advanced Dermatology PC, who indicates that recent research has moved scientists closer to understanding mechanisms of aging, including aging of skin, and the impact different substances have on cells and cellular processes.
However, Dr. Goldburt, a board-certified dermatologist, warns that more clinical, evidence-based studies of active ingredients in ointments and lotions are needed before physicians can declare what truly works in healing – and possibly reversing – skin damage caused by aging and sunlight.
Authors of a May 2017 article in the journal, Cosmetics, report that topical application of creams containing peptides appears to reduce wrinkles, improve skin volume and density, and increase overall skin tone. Peptides play key roles in natural processes like protein regulation, cell communication, blood-vessel development and immunity. They are advertised ingredients in some skin-care products.
In the same article, however, these researchers admit “a lot of additional work” is still required to understand the benefits and mode of action of the various peptides in commercial “anti-aging” formulations.
“There’s no guarantee that over-the-counter cosmetic creams and lotions will repair skin and offer the long-term restorative effects that a patient seeks,” Dr. Goldburt says. “Many commercial products fail to penetrate the top layer of skin. …
