Hydrating Efficacy and Tolerance Evaluation of a Face Cream

Study Overview
=================
Brief Summary
-----------------
Aim of the study was to evaluate by non-invasive instrumental evaluations tolerance and hydrating activity of a face topic product, to be applied twice a day, morning and evening, for an uninterrupted period of 8 weeks, by volunteers of both sexes, aged 45-60, who meet the inclusion and exclusion criteria required by the study procedure . It was also aim of this study to evaluate the hydrating activity of a single product application on the skin damaged by repeated stripping corneum (short term evaluation versus untreated control area).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of superficial skin hydration after a single product application | Variation of skin electrical capacitance value measured with Corneometer CM825 (Courage - Khazaka, Köln, Germany) after a single product application on the skin area damaged by corneum stripping | Immediately after stripping (T0i), 1 hour after product application (T1h), 8 hours after product application (T8h), 24 hours after product application (T24h) | 
| Change of transepidermal water loss (TEWL) after a single product application | Variation of transepidermal water loss value measured with Tewameter® TM300 (MPA 5 Courage-Khazaka, Germany) after a single product application on the skin area damaged by corneum stripping | Immediately after stripping (T0i), 1 hour after product application (T1h), 8 hours after product application (T8h), 24 hours after product application (T24h) | 
| Change of superficial skin hydration after repeated product application | Variation of skin electrical capacitance value measured with Corneometer CM825 (Courage - Khazaka, Köln, Germany) after repeated product application on the face | Baseline (T0), 4 weeks (T4), 8 weeks (T8) | 
| Change of deep skin hydration after repeated product application | Variation of tissue dielectric constant value of deep skin layers measured with MoistureMeterD (Delfin Technologies, Kuopio - Finland) after repeated product application on the face | Baseline (T0), 4 weeks (T4), 8 weeks (T8) |
