TEWL measurements
The TEWL measurements were carried out with
the Tewameter TM 210 (Courage + Khazaka
electronic GmbH, Cologne, Germany) on each
skin area before and 30 min after application,
respectively. Each set of measurements was
comprised of three individual measurements.
From these measurements, the mean value was
calculated. Our own experiences demonstrated
that a difference in TEWL values before and
after treatment of 8% could be neglected.
