Hydrating effects of moisturizer active compounds incorporated into hydrogels: in vivo assessment and comparison between devices.

Background: Water is an important factor on the appearance and function of the skin and, when dehydrated, it becomes rough and flaky. The measurement of stratum corneum hydration is widely employed to verify the moisture effect of topical products.

Aims: This study has evaluated in vivo the stratum corneum hydration, by the electrical measurements of skin, after treatment with different moisturizers presented in gel base.
