Skin conductance; validation of Skicon‐200EX^® compared to the original model, Skicon‐100^®

Abstract

The two Skicon instruments evaluated in this study correlated well, however, they displayed different levels depending on instrument main body and probes. Overall, the Skicon-200EX gave 1.6-fold higher value, and this instrument might be more sensitive than the original device, Skicon-100. In scientific reports, the type of instrument main body as well as probe shall be clearly specified.

Anatomical site variation of water content in human skin measured by the Epsilon: A pilot study

“…This pilot study is the first to measure water content of the SC in different body sites with the Epsilon. Our findings showed significant differences among the body sites, in correspondence with previous studies that also showed this trend . Many factors could influence these regional differences, for example, variations in the presence of sebaceous glands and lipids, natural moisturizing factor (NMF), size of corneocytes, exogenous compounds on skin surface and occlusion .…”

“…Our findings showed significant differences among the body sites, in correspondence with previous studies that also showed this trend. [5][6][7]12,13 Many factors could influence these regional differences, for example, variations in the presence of sebaceous glands and lipids, natural moisturizing factor (NMF), size of corneocytes, exogenous compounds on skin surface and occlusion. 4,12,14 Also, SC thickness variation could play a role; the smallest SC cell number is found in genital skin, followed by the face, neck, scalp, trunk, extremities and palmoplantar region.…”

“…A corneometer measures the water content by measuring electrical capacitance of the skin surface. Until today, single sensor corneometers are used, showing significant differences in water content between various skin locations . Recently, the Epsilon, a multi‐sensor corneometer with 76 800 sensors at one probe was introduced .…”

“…corneometers are used, showing significant differences in water content between various skin locations. [5][6][7] Recently, the Epsilon, a multi-sensor corneometer with 76 800 sensors at one probe was introduced. 8 Due to this increase in sensors, multiple measurements take place at once.…”

Influence of probe application pressure on in vitro and in vivo capacitance (Corneometer CM 825®) and conductance (Skicon 200 EX®) measurements

“…Technical descriptions of the conductance measuring system have been published by Tagami (17–19). The Skicon 200 EX ® is a more recent version of the Skicon 200, which has been described by O'Goshi and Serup (20). The instrument measures the conductance (readings in μS units) of a single high‐frequency current at 3.5 MHz.…”
