When the Dust Settles: Keratinocyte Differentiation is the Anti-pollution Solution


Daily, the human body encounters many stresses to which the skin acts as the first external barrier. Environmental pollution is one stressor and is present in many forms, including volatile organic compounds, cigarette smoke, ozone as well as particulate matter (PM). This persistent presence of urban pollution has become increasingly problematic in large cities worldwide. It affects not only the quality and beauty of skin, but also barrier function; these deleterious effects have been studied and demonstrated.1
