Pre-assignment details
The study consist of a screening period up to 15 day prior to randomization, a test period and a follow-up period. The study design is a within subject evaluation of the vasoconstriction properties of MC2-01 cream compared with vehicle cream and 5 other corticosteroids. All subjects received therefore a single treatment with all 7 products.

Comparison of the Vasoconstriction Potential (Skin Blanching Effect) of the MC2-01 Cream With Active Comparators and Vehicle
Blanching of the skin will be assessed individually by two trained observers blinded to treatment. The observers will score the blanching of the skin from 0-4 (0 = No change in color skin; 1 = Slight (barely visible) blanching; 3 = Obvious blanching; 4 = Blanching judged to be maximal). The results is presented as Mean ± SD.
Time frame: Day 2
Population: As the study design is a within subject evaluation of the vasoconstriction properties of MC2-01 cream compared with vehicle cream and 5 other corticosteroids, all 36 enrolled subjects received a single treatment with all 7 products.
