The notion of “beauty sleep” has been around for a long time, but physician-scientists at University Hospitals (UH) Case Medical Center have confirmed that sleep quality does, in fact, affect skin function and aging.
The recently completed study, commissioned by Estée Lauder, demonstrated 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 or ultraviolet (UV) radiation. Poor sleepers also had worse assessment of their own skin and facial appearance.
The research team led by Elma Baron, MD, presented their data this spring at the International Investigative Dermatology Meeting in Edinburgh, Scotland in an abstract titled “Effects of Sleep Quality on Skin Aging and Function.”

“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,” said Baron, director of the Skin Study Center at UH Case Medical Center and Associate Professor of Dermatology at Case Western Reserve University School of Medicine in a related wrapup article in Science Daily. “Insufficient sleep has become a worldwide epidemic. While chronic sleep deprivation has been linked to medical problems such as obesity, diabetes, cancer and immune deficiency, its effects on skin function have previously been unknown.”
The researchers found statistically significant differences between good and poor quality sleepers. Using the SCINEXA skin aging scoring system, poor quality sleepers showed increased signs of intrinsic skin aging including fine lines, uneven pigmentation and slackening of skin and reduced elasticity.
