Review of Advances in the Measurement of Skin Hydration Based on Sensing of Optical and Electrical Tissue Properties

Abstract: The presence of water in the skin is crucial for maintaining the properties and functions of the skin, in particular its outermost layer, known as the stratum corneum, which consists of a lipid barrier. External exposures can affect the skin’s hydration levels and in turn, alter its mechanical and physical properties. Monitoring these alterations in the skin’s water content can be applicable in clinical, cosmetic, athletic and personal settings. Many techniques measuring this parameter have been investigated, … Show more

“…External factors can influence cutaneous hydration levels, thereby resulting in changes to mechanical and physiological skin parameters. The analysis of potential alterations in the skin's water content can provide valuable information 65 . Both Skinly and commonly used Corneometer CM 825 showed very similar and statistically significant results regarding the difference in hydration relative to baseline values after treatment.…”

“…However, the transmission depth for both sensors is different; hence the spatial wavelength or the electrodic gap differs. Hydration sensors have a more significant gap since the measurement is deep within the dermis [42]. In the case of sweat sensors, the gap is very small since the measurement is only from the skin surface.…”

“…358,661 Competitors to Epicore for hydration monitoring include Nix Biosensors, FlowBio, and hDrop. 662,663 In contrast to the Gx sweat patch, these devices utilize integrated electrical components. Nix calculates sweat rate, electrolyte loss rate, and sweat composition in the sweat collection channel and transmits this data wirelessly.…”
