ZOOM#29: T-Skin®, an in vitro screening test that highlights the barrier effect of skincare products by Microfactory

All cosmetic products have a barrier effect that is difficult to measure on volunteers. T-Skin® uses microfluidics to mimic the evaporation of water from the skin by combining a synthetic polymer skin and a sensor measuring transepidermal water loss (TEWL). This innovation has been recently validated by the first in vivo/in vitro correlation measurements.

By faithfully reproducing the human TEWL, T-skin® simplifies these measurements, discriminate objectively the formulations with regards to their performances and validates product claims such as protective effect, Film-forming effect of ingredients, Absorbing effect of ingredients and even Anti-perspirant effect.
