Abstract

A non-invasive device for the quantitative determination of the level of oxidants and/or antioxidants in the skin of a subject includes a reference electrode and a working electrode which are connected to an electrical voltage measuring device; and a test solution container which is open at a bottom side thereof and which is placed on the skin of the subject and is sealingly but releasably affixed to the skin, is filled with a test solution, and which permits contact between the test solution and the skin. The test solution container further includes a top opening through which the electrodes are immersed in the test solution.
