Cutaneous microdialysis: is it worth the sweat?

Microdialysis is a minimally invasive technique for chronological study of metabolic, biochemical, and pharmacological events in living tissue. In the skin, probes are placed in the dermis or subcutis for research in two main areas, percutaneous penetration and various aspects of inflammation. Advances in technique, and the concept of data generation and analysis are leading to new areas of application.
