Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Outcomes are strength of dermo-epidermal adhesion (the time it takes for the suction blister to form, in minutes), transepidermal water loss (TEWL), skin hydration (SCH), skin pH, surface topography and skin elasticity, epidermal thickness and skin dryness. In addition, the blister fluid and the blister skin will be analyzed in the laboratory for biomarkers of dry skin (interleukins; IL-1a, IL-6, IL-8) by ELISA. | — |
