简要总结
The objective of this exploratory study is to gain an understanding of cutaneous and systemic inflammation and how restoration of the skin barrier through the use of moisturizer may restore the skin barrier function and reduce systemic inflammation in elderly humans compared to the young. The exploratory study will consist of three visits per subject. Subjects will be instructed to apply a moisturizer (Vanicream Moisturizing Skin Cream) over the entire skin surface from the neck down twice daily for up to 30 days.

结局指标
主要结局
Change in skin hydration status in aged and young subjects
时间窗: up to 30 days
Trans-epidermal water loss (TEWL) will be performed on the upper arm and buttocks at Visits 1 and 2. This instrument will measure the amount of water that is lost through the skin. The change in skin hydration status in each subject will be assessed and compared between groups.
