Sebum and water content in the skin of aged immobilized patients.

In the present study we investigated the sebum content and hydration of the skin in aged immobilized patients. Healthy aged as well as young and aged immobilized patients were evaluated by photometry, using a sebum tester and capacitance meter to detect sebum and hydration, respectively, in various skin areas. Sebum content was significantly higher in the young groups as compared to the aged ones, including those of the immobilized patients. Similar values of water content were observed in the healthy young and aged volunteers. However, surprisingly, a significantly marked decrease was detected in each tested area of the immobilized patients. We may assume that a cascade of events caused by the immobilization status of the patients leads to a significant decrease in water content within the dermis.
