Abstract:Transepidermal water loss (TEWL) and surface capacitance measure skin barrier permeability and skin hydration, respectively, and are frequently utilized in atopic dermatitis clinical trials. Conventional devices used to measure TEWL and hydration are often costly, bulky, and technically challenging, limiting their use to tertiary care facilities and research centers. GPSkin, a novel commercially-available device measures TEWL and skin hydration utilizing a compact, low-cost probe designed for patient operation… Show more
