研究概览
简要总结
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).
