Estee Lauder Companies presented data from its first-of-a-kind clinical trial held at University Hospitals (UH) Case Medical Center in Cleveland, Ohio, at the International Investigative Dermatology Meeting in Edinburgh, Scotland in May. The study, "Effects of Sleep Quality on Skin Aging and Function," which was commissioned by the company, revealed that poor sleepers had increased signs of skin aging and slower recovery from a variety of environmental stressors, such as disruption of the skin barrier and ultraviolet (UV) radiation. Elma Baron, MD, director of the Skin Study Center at UH Case Medical Center and associate professor of dermatology at Case Western Reserve University School of Medicine, commented, "Our study is the first to conclusively demonstrate that inadequate sleep is correlated with reduced skin health and accelerates skin aging. Sleep-deprived women show signs of premature skin aging and a decrease in their skin's ability to recover after sun exposure.”
