TEWL - Trans epidermal water loss
The skin as the largest organ of the human body has many functions. A key one is the barrier function to the outside world. Its purpose is to prevent excessive loss of moisture and intake of harmful microorganisms and toxic substances. A recognized clinical parameter to measure the condition of the skin barrier is the Trans epidermal Water Loss (TEWL) metric. Even if no dysfunctions are visible, increased TEWL values can already indicate barrier damage to the skin. The diseases characteristically damage the ceramides / cells of the skin, which can be used as a basis for the diseases as a diagnosis of the TEWL value as well as the severity of the disease.
Schematic figure of the human skin, consisting of skin cells and lipids, which form the human skin barrier. The measuring head of dermaMeter® is placed on the skin and draws water vapour into the sensor in the measuring chamber.
Measuring principle
As a result of diffusion of the body’s water, a pressure builds up, which can be measured as TEWL (in g/hm²). The system measures the water vapour flow density: JV= g/(m² x h) (mass of water vapour (in g) per area (in m2) and time (in h)). The technology of dermaMeter® is based on the principle of gas tomography. A measurement chamber is open on one side, measuring the gas concentration of water vapor that comes through a specific hygiene cap. The disposable hygiene cap only lets through water vapor to be measured. This results not only in reproducible and reliable results, but also assures absolutely hygienic measurement standard.
