“…After the participant had rested in supine position and their arms in supination for 10 min, 15 the probe was placed in contact with the skin at the marked point and held in position for 10 sec using gentle pressure, at which time an audible signal indicated the measurement was complete. 14 Measurements were obtained twice at the same point on the arm with each of the three different sized probes.…”

“…14 The volume of tissue and depth of penetration is determined by the surface of the probe in contact with the skin providing a focal measurement of tissue water. 15 Conventional tetrapolar bioimpedance analysis is sensitive in detecting increased extracellular fluid characteristic of early lymphedema. 16 As lymphedema progresses, it is characterized by changes in soft tissue composition such as increased skin thickness and adipose and fibrotic tissue.…”

“…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 .…”

BackgroundThis pilot study aimed to investigate the anatomical site variation of water content of the stratum corneum (SC) on the body by measuring skin capacitance with the Epsilon, a new generation corneometer with multiple sensors. Secondly, values of the Epsilon were compared to values measured by conventional single sensor corneometers.MethodsThe hydration status of SC was measured in 15 healthy Caucasian volunteers with the Epsilon at five body sites (cheek, lower forearm, mid‐calf, lower back and abdomen). Transepidermal water loss (TEWL) was measured with the Aquaflux to get more insight into the condition of the skin barrier. A literature search was performed to compare Epsilon values with conventional corneometers.ResultsThe tested anatomical locations showed significant differences in water content (P < 0.001) with large interindividual variations; highest values were found in the cheek (11.64ε) and lowest values in the mid‐calf (4.43ε). No correlation between water content and TEWL was found. In general, Epsilon values were lower compared to values of conventional corneometers, with a similar trend.ConclusionThis pilot study showed significant variations in water content at different skin locations measured by the Epsilon. Moreover, the Epsilon measured consistent lower values compared to single sensor corneometers. Further validation of the device is recommended.

“…Because of large intraindividual differences in skin barrier function across the human body [6,7,8,9,10], it is important to measure standardized and comparable skin areas to reliably quantify morphological or functional skin changes over time within the same or between different groups of individuals. There is strong evidence that, for instance, the TEWL varies widely even in small skin areas like the volar forearm.…”

Background: Biophysical skin measurement techniques are widely used to quantify the skin barrier function. In clinical research usually several parameters are subsequently measured in the same skin areas. In this study, possible interfering effects of subsequent measurement procedures on transepidermal water loss (TEWL), stratum corneum hydration (SCH) and skin surface pH were investigated. Methods: An exploratory study was conducted. Twelve young (mean age 32.9 ± 7.2 years) and 12 elderly (mean age 68.3 ± 2.5 years) subjects without any skin diseases were enrolled. The parameters TEWL, skin surface pH, SCH, sebum content, and surface evaluation of living skin were obtained successively in pairs from 4 contralateral volar forearm skin areas. Results: SCH and skin surface pH seemed to be unaffected by previous measurement procedures. TEWL was systematically increased after pH and systematically decreased after stratum corneum measurements. Conclusions: Measurements per se might interact with the skin, thus changing its characteristics. If several skin barrier function parameters need to be assessed subsequently in the same skin areas, we recommend that TEWL should be measured first followed by all others.
