Redox Stress in Skin Biology and Medicine: Implications for Skin Aging This SI will focus on redox stress as cause and consequence of skin aging. Guest editors: Prof Florian Gruber , Medical University of Vienna, Austria Prof Michail Rallis , Department of Pharmacy, National and Kapodistrian University of Athens, Greece Prof Karin Scharffetter-Kochanek , Department of Dermatology and Allergic Diseases, Ulm University, Ulm, Germany Special issue information: Overview Redox stress is central in aging of skin, which is exposed more than other organs to extrinsic but also intrinsic redox stressors. This SI will focus on redox stress as cause and consequence of skin aging. It will highlight the role of redox stress as messenger of exposure to pollution, radiation and xenobiotics, as causative or secondary agent in age related changes of the skin structure and molecular composition. We cover the dynamics of senescent cells in aging and regeneration, the (dys-) regulation of pigmentation the
