Noninvasive Potentiometric Method of Determination of Skin Oxidant/Antioxidant Activity

A noninvasive potentiometric method of determining skin oxidant/antioxidant activity is proposed that allows to measure, the shift of the potential of the mediator system applied to the skin in a mixture with a conductive gel. Direct correlation between the concentration of oxidants or antioxidants in the skin and related compounds, extracted from the skin to gel is proved mathematically. The possibility of using characteristics of skin OA/AOA as a criterion for assessing human health is discussed.
