Techniques

TEWL

Several techniques are proposed for TEWL on the one hand with a patented technique that overcomes the challenges of closed-chamber measurement through the use of a capacitor that continuously removes water vapor by transforming it into ice.

Raman spectrometry

RAMAN confocal spectroscopy is a technique for recovering the backscattered spectrum at different depths in a material. Applied to the skin, this technique measures the level of hydration in the different layers of the skin or the penetration of an active product into the same layers
