Abstract

The invention relates to a device (1) which is used to measure the physicochemical properties of the skin (8), such as the pH and oxidation state thereof. The inventive device comprises means (9) of generating, regulating and processing electric voltages, which are connected to means (2) of measuring properties of the skin, said measuring means comprising a working electrode (4), a reference electrode (5) and an auxiliary electrode (6). The invention is characterised in that the electrodes (4, 5, 6) can be brought into direct contact with the skin while the measurements are being taken. The invention also relates to methods of producing and using one such device (1).
