Transepidermal Water Loss (TEWL) via DermaLab Evaporimeter

Transepidermal Water Loss (TEWL) via DermaLab Evaporimeter – Transepidermal Water Loss (TEWL), the low level of moisture that constantly transpires through the skin, is measured with a computerized Evaporimeter using the DermaLab System (cyberDERM, Inc. Cortex Technology, Penn.). A built-in A/D (analog-to-digital) converter streams data for analysis. A reduction in TEWL generally indicates proportionately high film (barrier) integrity and/or wound closure in wound healing studies.
