研究概览
简要总结
The objective of this POC clinical study is to investigate the impact of the test product (Developmental Cosmetic Moisturising Cream) on skin barrier function and skin moisturisation on the forearm and face after 4 weeks of twice daily application compared to no treatment in participants with dry sensitive skin.
详细描述
Areas on the volar forearm and each side of the face, will be selected for measurements of transepidermal water loss (TEWL) and corneometry to be conducted . A physical challenge and a regression period of 5 days is also included to evaluate skin barrier function and moisturisation.
A regression period of 5 days (Days 30, 31, 32, 33 and 34) of no study product use following the 4 week treatment phase is also included to evaluate skin barrier function and moisturisation.

结局指标
主要结局
Change From Baseline in Transepidermal Water Loss (TEWL) Measurements on Day 29, Test Product Treated Versus (vs.) Untreated Sites on the Forearm
时间窗: At Baseline and Day 29
TEWL measuring principle is based on water vapour gradient determination between two pairs of sensors placed at different distances perpendicularly to the skin. The probe was held in place on the skin for one measurement, for approximately 40 seconds (sec), to ensure that a stable value has been established. The first part of the measurement belongs to the equilibration phase. The values of the last 10 secs were averaged as the actual measurement values. An increase in TEWL values shows damage to the skin barrier function.
