Construction, in vitro and in vivo evaluation of an in-house conductance meter for measurement of skin hydration

Analytic parallel‐polarized light imaging technique using various light‐emitting diodes: a comparison with skin conductance values

“…The measurement of skin hydration is important for assessment of the progression of various skin diseases and conditions . A simple and inexpensive skin conductance meter was reported and successfully assessed skin hydration in vivo . In our results, skin conductance values showed significant relationships with glossiness, dryness, and CIELAB coordinates.…”

“…For example, an objective and reliable measurement device is required for the measurement of skin hydration levels. An in‐house conductance meter is a simple and inexpensive set of instruments and accurately measures skin conductance values . The additional purpose of the study was to assemble a reliable skin conductance meter and utilize it on the correlation with several colorimetric values and other properties of skin.…”

Application of Microfluidics in Wearable Devices

“…The water content of the skin, especially the stratum corneum, is responsible for keeping the skin smooth and soft . Improper skin hydration can lead to eczema, atopic dermatitis and accelerates the aging of skin, thus precise and quantitative monitoring of skin hydration is useful in preventing skin‐based pathologies, and regulating external appearance .…”

“…Each device offers a unique possibility of studying a specific phenomenon in intact skin that may correlate to skin hydration level. But the most reliable and established skin hydration measurement is based on impedance monitoring since the skin hydration level is reflected by electronic or thermal parameters, such as thermal conductivity, thermal diffusivity, volumetric heat capacity and electrical impedance (Figure B). The measurement principle is to correlate the electrical or thermal parameters of biological tissues to their water content, and a plenty of devices have already been developed based on this conception .…”

Effect of Plant- Based ParabenFree Venusia Max Cream on Skin Hydration in HealthyIndividuals with Dry Skin

“…SC and its insoluble lipid layer primarily have water retention property and act as a natural moisturizer; and physical barrier against chemical, microbial and mechanical stress [3,4]. When water content of the skin is below 10%, then the visible appearance of dry and flaky skin is observed [5]. Skin dryness primarily increases with age as it alters the SC's keratinization processes and lipid contents [6].…”
