Role of Particulate Matter in Skin Inflammation

Environmental pollution is a major global problem that affects human health. Among different types of environmental pollution, particulate matter (PM) has a key role. As PM spreads in the air so it causes different bronchial and skin inflammatory conditions. PM increases oxidative stress by ROS production and pro-inflammatory cytokines. As a result, matrix metalloproteinase is also produced, such as MMP1, MMP9 and MMP2 that is a known major cause of skin collagen degradation. Recently it has been shown that the PM worsens allergic conditions like dermatitis, psoriasis, and skin cancer. Different extensive efforts have been made across the globe to control this PM.
