Assessment of Skin Tolerance and Efficacy of a Cosmetic Product After 5 Days of Use on Subjects With Atopic Dermatitis

The objective of this exploratory study is to investigate the efficacy and tolerability of a cosmetic product on subjects with atopic dermatitis after 5 days of use in comparison to a benchmark product.

The efficacy will be evaluated via instrumental measurements of skin hydration by Corneometer, transepidermal water loss by Tewameter and erythema by Chromameter as well as by evaluation of itch by using a Numerical Rating Scale (NRS). For efficacy and tolerability evaluation an objective and, in the case of adults, an additional subjective dermatological assessment will be performed.
