Transepidermal water loss (TEWL)
Water evaporates from the surface of the skin all the time, which states part of the human body’s metabolism. The evaporation rate of water from the skin surface is expressed in g/h/m^2. The Tewameter TM Hex probe, a direct successor to the well-known Tewameter TM 300 probe, is used to accurately measure water loss through the skin surface.
