The skin moisture was determined by means of the Corneometer® CM 825 (Courage & Khazaka, Cologne, Germany) before (initial value) and 0, 1, 2, 3, 4, and 5 h after application of the product. Three independent measurements per test area were performed at each point in time and values were averaged.
All measurements were performed at constant temperature (21 ± 1°C) and humidity (54 ± 4%) after the tissue had acclimatized to the given conditions for 30 min. An untreated area served as control.
