EEMCO guideline on skin water measurements

The experts make it clear: the open chamber method of the Tewameter® is the best.

The EEMCO group (European group on efficacy measurement and evaluation of cosmetics and other products) issue their revised guidance on skin water measurements.

The published guideline (Skin Research & Technology, 2018, 24, p. 351-358) considers all existing and new methods for the measurement of the skin barrier.

The experts say: ..."From skin barrier damage experiments, it became clear that the Tewameter with an open-chamber is more sensitive or disiminative and able to detect significantly smaller differences than the VapoMeter.

In addition, the closed chamber device is currently not sensitive enough to measure diurnal rhythm and fluctuations of skin as a function of time. ... Thus, the closed chamber instrument is inferior to the open-chamber measurement of TEWL ...".

The guideline also mentions the Corneometer® and MoistureMap.
