Measuring transepidermal water loss: a comparativein vivostudy of condenser-chamber, unventilated-chamber and open-chamber systems

Background/aims: Two main systems have been utilized for measuring transepidermal water loss (TEWL): open chamber and closed chamber. Yet, further validation and standardization studies may be necessary to reveal the sensitivity, precision, and robustness of these instruments. Methods: Three instruments are compared for their applicability to assess TEWL: unventilated chamber, open chamber and condenser chamber. The comparative study was...
