Oxidative Stress in Atopic Dermatitis and Possible Biomarkers: Present and Future

Oxidative stress is important in the pathogenesis of atopic dermatitis (AD); it can damage keratinocytes, increase dermal inflammation, and reduce skin barrier function, the hallmarks of atopic dermatitis pathogenesis. Measuring oxidative stress is possible by identifying peripheral markers, which could have a predictive value of disease severity, disease progression and response to therapy, with a potentially significant impact on patient management. Our review explored this fascinating field of research, focusing on old and new possible biomarkers that may represent an effective tool to investigate the inflammatory-oxidative axis in AD, adding clinically important information to patient care.
