Tewameter®

The Tewameter® is a measuring device for the assessment of the trans-epidermal water loss (TEWL). This parameter provides information on the integrity of the skin protective barrier functions.

The measurements are performed by the application of a probe to the skin surface for 30 seconds. Upon contact, the water evaporation rate (g/h/m²)is obtained.

High values of TEWL reflect a damaged skin barrier function.
