Background/aims: Some electrical properties of the skin may be related to the water content of the horny layer, and measurements of impedance and/or capacitance have been used to assess the hydration state of the skin surface. This study was designed to compare three commercially available instruments used in dermato-cosmetic research, namely, the Corneometer CM 825, the Nova DPM 9003 and the Skicon-200. Methods: Comparative measurements were carried out with the three instruments in vivo on the volar part of the forearms of 12 human volunteers. Results: The decrease in hydration induced by an irritant cationic detergent, and the increase of hydration after application of a moisturizer cream under occlusion could be easily measured with the three instruments. High degrees of correlation were obsewed between the three instruments over a broad range of hydration values of the skin. Conclusions: This comparative study performed under controlled environmental conditions reveals that the three instruments give validated coherent information concerning relative changes in hydration of the upper layers of the epidermis. |
